In order to support build_skb with jumbo frames it will be necessary to use
3K buffers for the Rx path with 8K pages backing them.  This is needed on
architectures that implement 4K pages because we can't support 2K buffers
plus padding in a 4K page.

In the case of systems that support page sizes larger than 4K the 3K
attribute will only be applied to FCoE as we can fall back to using just 2K
buffers and adding the padding.

Batch the page count updates instead of doing them one at a time.  By doing
this we can improve the overall performance as the atomic increment
operations can be expensive due to the fact that on x86 they are locked
operations which can cause stalls.  By doing bulk updates we can
consolidate the stall which should help to improve the overall receive
performance.

one due to the fact that page mapping and unmapping only has to sync what

2. Create a link to the leaf hash table from the base hash table with

3. Add filter in leaf hash table with match on next header fields and

This field is used to record the RX queue index for a redirect action

For ex: after adding a filter rule to redirect to a VF using ethtool
  # echo 4 > /sys/class/net/p4p1/device/sriov_numvfs
  # ethtool -N p4p1 flow-type ip4 src-ip 192.168.0.1 action 0x100000000

querying for the rule shows the Action as 'Direct to queue 0'

  # ethtool -n p4p1
  4 RX rings available
  Total 1 rules

  Filter: 2045
 	Rule Type: Raw IPv4
	Src IP addr: 192.168.0.1 mask: 0.0.0.0
	Dest IP addr: 0.0.0.0 mask: 255.255.255.255

	VLAN EtherType: 0x0 mask: 0xffff
	VLAN: 0x0 mask: 0xffff
	User-defined: 0x0 mask: 0xffffffffffffffff
	Action: Direct to queue 0

With this fix, ethtool will report the right queue index even for VFs.
	Action: Direct to queue 4294967296

Here 4294967296 corresponds to 0x100000000.
We need to update 'ethtool' to report the queue index as a Hex value so
that it is more  user friendly and matches with the 'action' value that
is passed when adding the rule.

Previously the PF driver would only set VLAN spoof checking if
the VF had created VLANs. This was done by setting and checking
a counter (vlan_count) whenever a VLAN was created by the VF.
However it is possible for the vlan_count to be !=0 while there are
no VLANs assigned to the VF due to the count incrementing every
time a VLAN 0 is added on ifdown/up, which resulted in VLAN spoofing
always being set for those VFs.

This patch cleans up the logic by unconditionally setting VLAN based on
how the VF is configured (via ip link set ethX vf Y spoofchk on/off).
This change also resolves an issue where the VLAN spoofing can remain
set even after being disabled by the user due to the driver enabling
VLAN spoof checking every time a VLAN is added to the VF, but would
only allow changes in the setting if vlan_count != 0.

Also default_vf_vlan_id and vlans_enabled were removed from the

The VXLAN port number should be stored in network order instead of in host
order as it is accessed from the hot-path in ATR.  This way we can avoid
having to do any byte swaps in order to validate the port number.

I moved the vxlan_port value into a hole in the read-mostly region of the
adapter struct.  This way it should be in a warm cache-line instead of in
some isolated region in memory when it needs to be accessed.

In addition I went through and stripped a bunch of unneeded ifdef flags
since having an extra variable present doesn't really hurt anything and
makes the code easier to read.  I also went through and dropped the

This adds initial support for offloading the u32 tc classifier. This
initial implementation only implements a few base matches and actions
to illustrate the use of the infrastructure patches.

However it is an interesting subset because it handles the u32 next
hdr logic to correctly map tcp packets from ip headers using the ihl

Also only the drop action is supported initially.

This patch adds support for VLAN promiscuous with SR-IOV enabled.

The code prior to this patch was only adding the PF to VLANs that the VF
had added.  As such enabling promiscuous mode would actually not add any
additional VLAN filters so visibility was limited.  This lead to a number
of issues as the bridge and OVS would expect us to accept all VLAN tagged
packets when promiscuous mode was enabled, and instead we would filter out
most if not all depending on the configuration of the PF.

With this patch what we do is set all the bits in the VFTA and all of the
VLVF bits associated with the pool belonging to the PF.  By doing this the
PF is guaranteed to receive all VLAN tagged traffic associated with the RAR
filters assigned to the PF.  In addition we will clean up those same bits
in the event of promiscuous mode being disabled.

In the process of tracking down a memory leak when adding/removing FDB
entries I had to go through the MAC address configuration code for ixgbe.
In the process of doing so I found a number of issues that impacted
readability and performance.  This change updates the code in general to
clean it up so it becomes clear what each step is doing.  From what I can
tell there a couple of bugs cleaned up in this code.

First is the fact that the MAC addresses were being double counted for the
PF.  As a result once entries up to 63 had been used you could no longer
add additional filters.

A simple test case for this:
  for i in `seq 0 96`
  do
    ip link add link ens8 name mv$i type macvlan
    ip link set dev mv$i up
  done

Test script:
  ethregs -s 0:8.0 | grep -e "RAH" | grep 8000....$

When things are working correctly RAL/H registers 1 - 97 will be consumed.
In the failing case it will stop at 63 and prevent any further filters from
being added.

The limitation of the number of multicast address for VF is not enough
for the large scale server with SR-IOV feature. IPv6 requires the multicast
MAC address for each IP address to handle the Neighbor Solicitation
message. We couldn't assign over 30 IPv6 addresses to a single VF.

This patch introduces the new mailbox API, IXGBE_VF_UPDATE_XCAST_MODE,
to update multicast mode of VF. This adds 3 modes;
  - NONE     only L2 exact match addresses or Flow Director enabled
  - MULTI    BAM and ROMPE set
  - ALLMULTI BAM, ROMPE and MPE set

If a guest VF user wants over 30 MAC multicast addresses, set IFF_ALLMULTI
to request PF to update xcast mode to enable VF multicast promiscuous mode.

On the other hand, enabling VF multicast promiscuous mode may affect
security and performance in the network of the NIC. Only trusted VF can
enable multicast promiscuous mode. The behavior of untrusted VF is the
same as previous version.

This patch updates the lowest limit for adaptive interrupt interrupt
moderation to roughly 12K interrupts per second.

The way I came about reaching 12K as the desired interrupt rate is by
testing with UDP flows.  Specifically I had a simple test that ran a
netperf UDP_STREAM test at varying sizes.  What I found was as the packet
sizes increased the performance fell steadily behind until we were only
able to receive at ~4Gb/s with a message size of 65507.  A bit of digging
found that we were dropping packets for the socket in the network stack,
and looking at things further what I found was I could solve it by increasing
the interrupt rate, or increasing the rmem_default/rmem_max.  What I found was
that when the interrupt coalescing resulted in more data being processed
per interrupt than could be stored in the socket buffer we started losing
packets and the performance dropped.  So I reached 12K based on the
following math.

rmem_default = 212992
skb->truesize = 2994
212992 / 2994 = 71.14 packets to fill the buffer

packet rate at 1514 packet size is 812744pps
71.14 / 812744 = 87.9us to fill socket buffer

From there it was just a matter of choosing the interrupt rate and
providing a bit of wiggle room which is why I decided to go with 12K
interrupts per second as that uses a value of 84us.

The data below is based on VM to VM over a direct assigned ixgbe interface.
The test run was:

Implements the new netdev op to allow user to enable/disable the ability
of a specific VF to query its RSS Indirection Table and an RSS Hash Key.

Support for other devices will be added later.
