Sathya Perla posted a patch trying to address following problem :
<quote>
The vxlan driver sets itself as the socket owner for all the TX flows
it encapsulates (using vxlan_set_owner()) and assigns it's own skb
destructor. This causes all tunneled traffic to land up on only one TXQ
as all encapsulated skbs refer to the vxlan socket and not the original
socket. Also, the vxlan skb destructor breaks some functionality for
tunneled traffic like wmem accounting and as TCP small queues and
FQ/pacing packet scheduler.
</quote>
I reworked Sathya patch and added some explanations.
vxlan_xmit() can avoid one skb_clone()/dev_kfree_skb() pair
and gain better drop monitor accuracy, by calling kfree_skb() when
appropriate.
The UDP socket used by vxlan to perform encapsulation of xmit packets
do not need to be alive while packets leave vxlan code. Its better
to keep original socket ownership to get proper feedback from qdisc and
NIC layers.
We use skb->sk to
A) control amount of bytes/packets queued on behalf of a socket, but
prior vxlan code did the skb->sk transfert without any limit/control
on vxlan socket sk_sndbuf.
B) security purposes (as selinux) or netfilter uses, and I do not think
anything is prepared to handle vxlan stacked case in this area.
By not changing ownership, vxlan tunnels behave like other tunnels.
As Stephen mentioned, we might do the same change in L2TP.

When communicating with VF devices over the AQ, the FW refers to the
VF by its global VF ID, not local the VF ID with reference to its
parent PF. Since the global and local VF IDs are identical for PF 0,
the code worked correctly on PF 0.
However, we cannot just use global IDs throughout the code as most of
the other references to the VF (VSI setup, register offsets, etc.)
require the local VF ID. Instead, we just add or subtract our base VF
ID when sending and receiving AQ messages.

Enabling the default port on the VEB causes all outgoing traffic from
virtual functions to be copied to the physical function. The default
port is only supposed to be used if you wish to bridge the physical
function to a SW switch such as Open vSwitch or the Linux bridge. That
allows the SW switch to route traffic to VMs that are not using a
virtual function.
Eventually we'll want to implement the ndo_fdb_add, ndo_fdb_del, and
ndo_fdb_dump functions. The ndo_fdb_add function would set the
default port on the VEB in those cases where the MAC/VLAN address
filters have overflowed. Normally we would not want to use it.

The allocation and clearing of rings for a VSI should be
using the alloc_queue_pairs and not num_queue_pairs.
The alloc_queue_pairs per VSI is a pre-allocated number
of queues assigned to a VSI; based on number of TCs enabled
only certain number of queues may be used from that. This
is mainly valid only for the LAN VSI case as that is the
only VSI that may be enabled with multiple traffic classes.
In the future the number of TCs may change based on DCBX
configuration.
The actual number of queues that are enabled/configured is
based on the number of TCs enabled for a given VSI and that
is stored in num_queue_pairs.
With this change num_[tr]x_queues is unused so remove them.

When disabling and enabling VFs on a live system with the VF driver
loaded, it's possible to receive an admin queue message from the VF
driver at an inconvenient time, e.g. when the associated data structures
aren't present or configured. This causes a rather inconvenient panic.
To guard against this, we change the order of when we set num_alloc_vfs
when turning off SR-IOV, and then gate processing of any VF messages
based upon that value. Likewise, when enabling VFs, we shut off the
relevant interrupt until configuration is complete.

Intel Wired LAN Driver Updates
This series contains updates to i40e and pci_regs.h.
Anjali provides a patch to prevent messages from stray HMC events, except
at interrupt message level, and refactors the HMC error handling.
Catherine adds routines in probe to populate/check PCI bus speed and width,
then verify we are in a 8GT/s x8 PCIe slot and warn when we are not.
Shannon adds Wake-on-LAN support for i40e, fixes curly brace use as well as
return type for i40e_vsi_clear_rings().
Joseph implements receive offload for VXLAN for i40e, where the hardware
supports checksum offload/verification of the inner/outer header.
Mitch provides the bulk of the changes, where he refactors the VF reset
code so that it works on real hardware. Then does code cleanup by
calling existing functions to enable and disable queues for VFs and
remove unused functions. Removes a unnecessary log messages that are
seen at every VF reset, for example complaining about disabling queues
that are already disabled. Fixes an error return when the VF asks to
add an invalid MAC address and if the VF sends a bad message, make it
more informative about what is actually going on.
Jesse refactors the LED function to flash LED lights correctly.
v2:
- removed patch 5 "i40e: add set settings and pauseparam" based on
feedback from Ben Hutchings, will re-work that patch for later
submission
- Added patch "i40e: Implementation of vxlan ndo's" from Joseph to
address Or Gerlitz's questions and concerns. This patch adds the
implementation for the VXLAN ndo's and allows the hardware to do
receive checksum offload for inner packets on the UDP ports that
VXLAN notifies us about.
- Added patch "i40e: using for_each_set_bit to simplify the code"
from Wei Yongjun. This patch uses for_each_set_bit() to simply
the code.
v3:
- fixed indentation issue in patch 11 based on feedback from
Sergei Shtylyov.
Sorry for the delayed release of v4, it was delayed to the holidays.
v4:
- Addressed Or Gerlitz's concerns about trying to get a hold of a mutex
while holding a spin lock in patch 6 by executing the AQ commands from
a subtask.
- Addressed David Miller's Kconfig concerns by creating a Kconfig VXLAN
option for i40e and wrapped appropriate code with the config option in
patch 6.
- Updated patch 7 based on the changes made in patch 6 in the above two
bullets.
v5:
- Added the patch to pci_regs.h based on David Miller's feedback to add
PCI defines for speed and width
- Updated patch 3 description to better explain the changes based on
feedback from David Miller
- Updated patch 4 to use the newly added defines to pci_regs.h instead
of local defines
- Updated patch 7 to use <net/vxlan.h> in the #include based on feedback

- convert assignments to initializers;
- kill useless assignments before *return*.

A number of functions (especially in phy.c) has local variables that were hardly
needed in the first place -- remove them.

The recent patch from Florian Fainelli fixed all 'checkpatch.pl' errors but left
some warnings like:
- including <asm/io.h> instead of <linux/io.h>;
- including <asm/uaccess.h> instead of <linux/uaccess.h>;
- block comments using empty /* line;
- 'struct dev_pm_ops' variable not being *const*.
While fixing these, also fix the following style issues (some of which were
found running 'checkpatch.pl --strict'):
- alignment not matching open paren;
- file name in the heading comment.
