The max_vfs parameter has a limit of 63 and silently fails (adding 0 vfs) when
it is out of range. This patch adds a warning so that the user knows something
went wrong. Also, this patch moves the warning in ixgbe_enable_sriov() to where
max_vfs is checked, so that even an out of range value will show the deprecated
warning. Previously, an out of range parameter didn't even warn the user to use
the new sysfs interface instead.

This patch fixes multiple problems in the link modes display in ethtool.
Newer parts have more complicated methods to determine actual link
capabilities.  Older parts cannot communicate with their SFP modules.
Finally, all the available defines are not displayed by ethtool.  This
updates the link modes to be as accurate as possible depending on what data

Pushing original fragments through causes several problems. For example
for matching, frags may not be matched correctly. Take following
example:

<example>
On HOSTA do:
ip6tables -I INPUT -p icmpv6 -j DROP
ip6tables -I INPUT -p icmpv6 -m icmp6 --icmpv6-type 128 -j ACCEPT

and on HOSTB you do:
ping6 HOSTA -s2000    (MTU is 1500)

Incoming echo requests will be filtered out on HOSTA. This issue does
not occur with smaller packets than MTU (where fragmentation does not happen)
</example>

As was discussed previously, the only correct solution seems to be to use
reassembled skb instead of separete frags. Doing this has positive side
effects in reducing sk_buff by one pointer (nfct_reasm) and also the reams
dances in ipvs and conntrack can be removed.

Future plan is to remove net/ipv6/netfilter/nf_conntrack_reasm.c
entirely and use code in net/ipv6/reassembly.c instead.

If reassembled packet would fit into outdev MTU, it is not fragmented
according the original frag size and it is send as single big packet.

The second case is if skb is gso. In that case fragmentation does not happen
according to the original frag size.

The number of stations in use is kept in the num_rx_pools counter
in the ixgbe_adapter structure. This is in turn used by the queue
allocation scheme to determine how many queues are needed to support
the number of pools in use with the current feature set.

This works as long as the pools are added and destroyed in order
because (num_rx_pools * queues_per_pool) is equal to the last
queue in use by a pool. But as soon as you delete a pool out of
order this is no longer the case. So the above multiplication
allocates to few queues and a pool may reference a ring that has
not been allocated/initialized.

To resolve use the bit mask of in use pools to determine the final
pool being used and allocate enough queues so that we don't
inadvertently remove its queues.

In the recent support for layer 2 hardware acceleration, I added a
few references to real_num_rx_queues and num_rx_queues which are
only available with CONFIG_RPS.

The fix is first to remove unnecessary references to num_rx_queues.
Because the hardware offload case is limited to cases where RX queues
and TX queues are equal we only need a single check. Then wrap the
single case in an ifdef.

As the rfc 4191 said, the Router Preference and Lifetime values in a
::/0 Route Information Option should override the preference and lifetime
values in the Router Advertisement header. But when the kernel deals with
a ::/0 Route Information Option, the rt6_get_route_info() always return
NULL, that means that overriding will not happen, because those default
routers were added without flag RTF_ROUTEINFO in rt6_add_dflt_router().

In order to deal with that condition, we should call rt6_get_dflt_router
when the prefix length is 0.

When trying to delete a table >= 256 using iproute2 the local table
will be deleted.
The table id is specified as a netlink attribute when it needs more then
8 bits and iproute2 then sets the table field to RT_TABLE_UNSPEC (0).
Preconditions to matching the table id in the rule delete code
doesn't seem to take the "table id in netlink attribute" into condition
so the frh_get_table helper function never gets to do its job when
matching against current rule.
Use the helper function twice instead of peaking at the table value directly.

And...

"In this round for mac80211-next I have:

 * a CCM rewrite, using potential hardware offloads
 * SMPS for AP mode
 * RF-kill GPIO driver updates to make it usable as an ACPI driver
 * regulatory improvements
 * documentation fixes
 * DFS for IBSS mode
 * and a few small other fixes/improvements"

For the TI driver bits, Luca says:

"Some patches intended for 3.13.  Eliad continues upstreaming pending
patches from the internal tree."

For the iwlwifi bits, Emmanuel says:

"There are a few fixes from Johannes mostly clean up patches. We have
also a few other fixes that are relevant for the new firmware that has
not been released yet."

For the Bluetooth bits, Gustavo says:

"A last fix to the 3.12. I ended forgetting to send it before, I hope we can
still make the way to 3.12. It is a revert and it fixes an issue with bluetooth
suspend/hibernate that had many bug reports. Please pull or let me know of any
problems. Thanks!"  (Obviously, that one didn't make 3.12...)

Also...

"One more big pull request for 3.13. These are the patches we queued during
last week. Here you will find a lot of improvements to the HCI and L2CAP and
MGMT layers with the main ones being a better debugfs support and end of work
of splitting L2CAP into Core and Socket parts."

Additionally, there is one ath9k patch to enable DFS in IBSS mode for
that driver.

I appreciate your consideration for taking this extra pull request

Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next into for-davem

While testing virtio_net and skb_segment() changes, Hannes reported
that UFO was sending wrong frames.

It appears this was introduced by a recent commit :
8c3a897b ("inet: restore gso for vxlan")

The old condition to perform IP frag was :

tunnel = !!skb->encapsulation;
...
        if (!tunnel && proto == IPPROTO_UDP) {

So the new one should be :

udpfrag = !skb->encapsulation && proto == IPPROTO_UDP;
...
        if (udpfrag) {

Initialization of udpfrag must be done before call
to ops->callbacks.gso_segment(skb, features), as
skb_udp_tunnel_segment() clears skb->encapsulation

(We want udpfrag to be true for UFO, false for VXLAN)

Changing MTU size of an xgmac network interface while it is active can
cause a panic like

  skbuff: skb_over_panic: text:c03bc62c len:1090 put:1090 head:edfb6900 data:edfb6942 tail:0xedfb6d84 end:0xedfb6bc0 dev:eth0

  PC is at skb_panic+0x64/0x70
  LR is at wake_up_klogd+0x5c/0x68

This happens because xgmac_change_mtu modifies dev->mtu before the
network interface is quiesced. And thus there still might be buffers
in use which have a buffer size based on the old MTU.

To fix this I moved the change of dev->mtu after the call to
xgmac_stop.

Another modification is required (in xgmac_stop) to ensure that
xgmac_xmit is really not called anymore (xgmac_tx_complete might wake
up the queue again).

I've tested the fix by switching MTU size every second between 600 and
1500 while network traffic was going on. The test box survived a test
of several hours (until I've stopped it) whereas w/o this fix above
panic occurs after several minutes (at most).

Change since v1:
- remove call to netif_stop_queue at beginning of xgmac_stop
- use netif_tx_disable instead of locking+netif_stop_queue

l2 hardware accelerated macvlans

This patch adds support to offload macvlan net_devices to the
hardware. With these patches packets are pushed to the macvlan
net_device directly and do not pass through the lower dev.

The patches here have made it through multiple iterations
each with a slightly different focus. First I tried to
push these as a new link type called "VMDQ". The patches
shown here,

http://comments.gmane.org/gmane.linux.network/237617

Following this implementation I renamed the link type
"VSI" and addressed various comments. Finally Neil
Horman picked up the patches and integrated the offload
into the macvlan code. Here,

http://permalink.gmane.org/gmane.linux.network/285658

The attached series is clean-up of his patches, with a
few fixes.

If folks find this series acceptable there are a few
items we can work on next. First broadcast and multicast
will use the hardware even for local traffic with this
series. It would be best (I think) to use the software
path for macvlan to macvlan traffic and save the PCIe
bus. This depends on how much you value CPU time vs
PCIE bandwidth. This will need another patch series
to flush out.

Also this series only allows for layer 2 mac forwarding
where some hardware supports more interesting forwarding
capabilities. Integrating with OVS may be useful here.

As always any comments/feedback welcome.

My basic I/O test is here but I've also done some link
testing, SRIOV/DCB with macvlans and others,

Changelog:
v2: two fixes to ixgbe when all features DCB, FCoE, SR-IOV
    are enabled with macvlans. A VMDQ_P() reference
    should have been accel->pool and do not set the offset
    of the ring index from dfwd add call. The offset is used
    by SR-IOV so clearing it can cause SR-IOV quue index's
    to go sideways. With these fixes testing macvlan's with
    SRIOV enabled was successful.
