be2net: patch set

Hi Dave, the following patch set includes three feature additions relating
to SR-IOV to be2net.

Patch 1 avoid creating a non-RSS default RXQ when FW allows it.
This prevents wasting one RXQ for each VF.

Patch 2 adds support for evenly distributing all queue & filter resources
across VFs. The FW informs the driver as to which resources are distributable.

Patch 3 implements the sriov_configure PCI method to allow runtime
enablement of VFs via sysfs.

Pls consider applying this patch-set to the net-next tree. Thanks!

The statistics registers have write-clear behaviour, which means we
will lose any increment between the read and write.  Mitigate this by
only clearing when we read a non-zero value, so we will never falsely
report a total of zero.  This also saves time as we only handle
error statistics here and they won't often be incremented.

There are many different sets of registers implemented by the

get more complicated in future.  Limit how much ethtool needs to know
by including an explicit bitmap of which registers are included in the

As I don't have datasheets for all of these, I've only included
registers that are:

- defined in all 5 register type arrays, or
- used by the driver, or
- documented in the datasheet I have

Add one new capability flag so we can tell whether the RTRATE

Basic MPLS support take 2

On top of my two pending neighbour table prep patches here is the mpls
support refactored to use them, and edited to not drop routes when
an interface goes down.  Additionally the addition of RTA_LLGATEWAY
has been replaced with the addtion of RTA_VIA.  RTA_VIA being an
attribute that includes the address family as well as the address
of the next hop.

MPLS is at it's heart simple and I have endeavoured to maintain that
simplicity in my implemenation.

This is an implementation of a RFC3032 forwarding engine, and basic MPLS
egress logic.  Which should make linux sufficient to be a mpls
forwarding node or to be a LSA (Label Switched Router) as it says in all
of the MPLS documents.  The ingress support will follow but it deserves
it's own discussion so I am pushing it separately.

Unlike IPv4 this code notifies on all cases where mpls routes
are added or removed and it never automatically removes routes.

This change adds two new netlink routing attributes:
RTA_VIA and RTA_NEWDST.

RTA_VIA specifies the specifies the next machine to send a packet to
like RTA_GATEWAY.  RTA_VIA differs from RTA_GATEWAY in that it
includes the address family of the address of the next machine to send
a packet to.  Currently the MPLS code supports addresses in AF_INET,
AF_INET6 and AF_PACKET.  For AF_INET and AF_INET6 the destination mac
address is acquired from the neighbour table.  For AF_PACKET the
destination mac_address is specified in the netlink configuration.

I think raw destination mac address support with the family AF_PACKET
will prove useful.  There is MPLS-TP which is defined to operate
on machines that do not support internet packets of any flavor.  Further
seem to be corner cases where it can be useful.  At this point
I don't care much either way.

RTA_NEWDST specifies the destination address to forward the packet
with.  MPLS typically changes it's destination address at every hop.
For a swap operation RTA_NEWDST is specified with a length of one label.
For a push operation RTA_NEWDST is specified with two or more labels.
For a pop operation RTA_NEWDST is not specified or equivalently an emtpy
RTAN_NEWDST is specified.

Those new netlink attributes are used to implement handling of rt-netlink
RTM_NEWROUTE, RTM_DELROUTE, and RTM_GETROUTE messages, to maintain the
MPLS label table.

rtm_to_route_config parses a netlink RTM_NEWROUTE or RTM_DELROUTE message,
verify no unhandled attributes or unhandled values are present and sets
up the data structures for mpls_route_add and mpls_route_del.

I did my best to match up with the existing conventions with the caveats
that MPLS addresses are all destination-specific-addresses, and so
don't properly have a scope.

Reading and writing addresses in network byte order in netlink is
traditional and I see no reason to change that.  MPLS is interesting
as effectively it has variabely length addresses (the MPLS label
stack).  To represent these variable length addresses in netlink
I use a valid MPLS label stack (complete with stop bit).

This achieves two things: a well defined existing format is used,
and the data can be interpreted without looking at it's length.

Not needed to look at the length to decode the variable length
network representation allows existing userspace functions
such as inet_ntop to be used without needed to change their
prototype.

mpls_route_add and mpls_route_del implement the basic logic for adding
and removing Next Hop Label Forwarding Entries from the MPLS input
label map.  The addition and subtraction is done in a way that is
consistent with how the existing routing table in Linux are
maintained.  Thus all of the work to deal with NLM_F_APPEND,
NLM_F_EXCL, NLM_F_REPLACE, and NLM_F_CREATE.

Cases that are not clearly defined such as changing the interpretation
of the mpls reserved labels is not allowed.

Because it seems like the right thing to do adding an MPLS route without
specifying an input label and allowing the kernel to pick a free label
table entry is supported.   The implementation is currently less than optimal
but that can be changed.

As I don't have anything else to test with only ethernet and the loopback
device are the only two device types currently supported for forwarding
MPLS over.

This sysctl gives two benefits.  By defaulting the table size to 0
mpls even when compiled in and enabled defaults to not forwarding
any packets.  This prevents unpleasant surprises for users.

The other benefit is that as mpls labels are allocated locally a dense
table a small dense label table may be used which saves memory and
is extremely simple and efficient to implement.

This sysctl allows userspace to choose the restrictions on the label
table size userspace applications need to cope with.

This change adds a new Kconfig option MPLS_ROUTING.

The core of this change is the code to look at an mpls packet received
from another machine.  Look that packet up in a routing table and
forward the packet on.

Support of MPLS over ATM is not considered or attempted here.  This
implemntation follows RFC3032 and implements the MPLS shim header that
can pass over essentially any network.

What RFC3021 refers to as the as the Incoming Label Map (ILM) I call
net->mpls.platform_label[].  What RFC3031 refers to as the Next Label
Hop Forwarding Entry (NHLFE) I call mpls_route.  Though calling it the
label fordwarding information base (lfib) might also be valid.

Further the implemntation forwards packets as described in RFC3032.
There is no need and given the original motivation for MPLS a strong
discincentive to have a flexible label forwarding path.  In essence
the logic is the topmost label is read, looked up, removed, and
replaced by 0 or more new lables and the sent out the specified
interface to it's next hop.

Quite a few optional features are not implemented here.  Among them
are generation of ICMP errors when the TTL is exceeded or the packet
is larger than the next hop MTU (those conditions are detected and the
packets are dropped instead of generating an icmp error).  The traffic
class field is always set to 0.  The implementation focuses on IP over
MPLS and does not handle egress of other kinds of protocols.

Instead of implementing coordination with the neighbour table and
sorting out how to input next hops in a different address family (for
which there is value).  I was lazy and implemented a next hop mac
address instead.  The code is simpler and there are flavor of MPLS
such as MPLS-TP where neither an IPv4 nor an IPv6 next hop is
appropriate so a next hop by mac address would need to be implemented
at some point.

Two new definitions AF_MPLS and PF_MPLS are exposed to userspace.

Decoding the mpls header must be done by first byeswapping a 32bit bit
endian word into the local cpu endian and then bit shifting to extract
the pieces.  There is no C bit-field that can represent a wire format
mpls header on a little endian machine as the low bits of the 20bit
label wind up in the wrong half of third byte.  Therefore internally
everything is deal with in cpu native byte order except when writing
to and reading from a packet.

For management simplicity if a label is configured to forward out
an interface that is down the packet is dropped early.  Similarly
if an network interface is removed rt_dev is updated to NULL
(so no reference is preserved) and any packets for that label
are dropped.  Keeping the label entries in the kernel allows
the kernel label table to function as the definitive source
of which labels are allocated and which are not.

Neighbour table prep for MPLS

In preparation for using the IPv4 and IPv6 neighbour tables in my mpls
code this patchset factors out ___neigh_lookup_noref from
__ipv4_neigh_lookup_noref, __ipv6_lookup_noref and neigh_lookup.
Allowing the lookup logic to be shared between the different
implementations.  At what appears to be no cost. (Aka the same assembly
is generated for ip6_finish_output2 and ip_finish_output2).

After that I add a simple function that takes an address family and an
address consults the neighbour table and sends the packet to the
appropriate location.  The address family argument decoupls callers
of neigh_xmit from the addresses families the packets are sent over.
(Aka The ipv6 module can be loaded after mpls and a previously
configured ipv6 next hop will start working).

The refactoring in ___neigh_lookup_noref may be a bit overkill but it
feels like the right thing to do.  Especially since the same code is
generated.

For MPLS I am building the code so that either the neighbour mac
address can be specified or we can have a next hop in ipv4 or ipv6.

The kind of next hop we have is indicated by the neighbour table
pointer.  A neighbour table pointer of NULL is a link layer address.
A non-NULL neighbour table pointer indicates which neighbour table and
thus which address family the next hop address is in that we need to
look up.

The code either sends a packet directly or looks up the appropriate
neighbour table entry and sends the packet.

While looking at the mpls code I found myself writing yet another

So to make my work a little easier and to make it a smidge easier to
verify/maintain the mpls code in the future I stopped and wrote
___neigh_lookup_noref.  Then I rewote __ipv4_lookup_noref and
__ipv6_lookup_noref in terms of this new function.  I tested my new
version by verifying that the same code is generated in
ip_finish_output2 and ip6_finish_output2 where these functions are
inlined.

To get to ___neigh_lookup_noref I added a new neighbour cache table
function key_eq.  So that the static size of the key would be
available.

I also added __neigh_lookup_noref for people who want to to lookup
a neighbour table entry quickly but don't know which neibhgour table

Intel Wired LAN Driver Updates 2015-03-03

This series contains updates to fm10k, i40e and i40evf.

Matthew updates the fm10k driver by cleaning up code comments and whitespace
issues.  Also modifies the tunnel length header check, to make it more robust
by calculating the inner L4 header length based on whether it is TCP or UDP.
Implemented ndo_features_check() that allows drivers to report their offload
capabilities per-skb.

Neerav updates the i40e driver to skip over priority tagging if DCB is not
enabled.  Fixes an issue where the driver is not flushing out the
DCBNL app table for applications that are not present in the local DCBX
application configuration TLVs.  Fixed i40e where, in the case of MFP
mode, the driver was returning the incorrect number of traffic classes
for partitions that are not enabled for iSCSI.  Even though the driver
was not configuring these traffic classes in the transmit scheduler for
the NIC partitions, it does use this map to setup the queue mappings.

Shannon updates i40e/i40evf to include the firmware build number in the
formatted firmware version string.

Akeem adds a safety net (by adding a 'default' case) for the possible
unmatched switch calls.

Mitch updates i40e to not automatically disable PF loopback at runtime,
now that we have the functionality to enable and disable PF loopback.  This
fix cleans up a bogus error message when removing the PF module with VFs
enabled.  Adds a extra check to make sure that the indirection table
pointer is valid before dereferencing it.

Anjali enables i40e to enable more than the max RSS qps when running in a
single TC mode for the main VSI.  It is possible to enable as many as
num_online_cpus().  Adds a firmware check to ensure that DCB is disabled for
firmware versions older than 4.33.  Updates i40e/i40evf to add missing
packet types for VXLAN offload.  Updated i40e to be able to handle varying
RSS table size for each VSI, since all VSI's do not have the same RSS table
size.
