      inet: move ipv6only in sock_common · 9fe516ba
      Eric Dumazet authored 
      When an UDP application switches from AF_INET to AF_INET6 sockets, we
have a small performance degradation for IPv4 communications because of
extra cache line misses to access ipv6only information.

This can also be noticed for TCP listeners, as ipv6_only_sock() is also
used from __inet_lookup_listener()->compute_score()

This is magnified when SO_REUSEPORT is used.

Move ipv6only into struct sock_common so that it is available at
no extra cost in lookups.

====================
Intel Wired LAN Driver Updates 2014-07-01

This series contains updates to i40e, i40evf, igb and ixgbe.

Shannon adds the Base Address High and Low to the admin queue structure
to simplify the logic in the configuration routines.  Also adds code to
clear all queues and interrupts to help clean up after a PXE or other
early boot activity.

Kevin fixes mask assignment value since -1 cannot be used for unsigned
integer types.

Mitch fixes an issue where in some circumstances the reply from the PF
would come back before we were able to properly modify the admin queue
pending and required flags.  This would mess up the flags and put the
driver in an indeterminate state, so fix this by simply setting the flags
before sending the request to the admin queue.  Also changes the branding
string for i40evf to reduce confusion and to match up with our other
marketing materials.

Kamil adds a new variable defining admin send queue (ASQ) command write
back timeout to allow for dynamic modification of this timeout.

Anjali fix a bug in the flow director filter replay logic, so that we
call a replay after a sideband reset correctly.

Jesse adds code to initialize all members of the context descriptor to
prevent possible stale data.

Christopher fixes i40e to prevent writing to reserved bits, since the
queue index is only 0-127.

Jacob removes the unneeded header export.h from the i40e PTP code.
Fixes ixgbe PTP code where the PPS signal was not correct, as it
generates a one half HZ clock signal, it only generates one level
change per second.  To generate a full clock, we need two level changes
per second.

Todd provides a fix for igb to bring up link when the PHY has powered
up, which was reported by Jeff Westfahl.

      This limitation maybe had some reason in the past, but now there is not
one -> removing this.

====================
cxgb4: Fix for PCI passthrough and some Misc. fixes

This patch series fixes probe failure in VM when PF is exposed through PCI
Passthrough. Adds support to use firmware interface to get BAR0 value.
Replace the backdoor mechanism to access the HW memory with PCIe Window method
which fixes memory I/O. Also adds device ID of few more adapters for cxgb4 and
cxgb4vf driver.

The patches series is created against 'net-next' tree.
And includes patches on cxgb4, cxgb4vf and iw_cxgb4 driver.

Since this patch-series contains mainly cxgb4 related changes, we would like to
request this patch series to get merged via David Miller's 'net-next' tree.

We have included all the maintainers of respective drivers. Kindly review the
change and let us know in case of any review comments.

      cxgb4: Replaced the backdoor mechanism to access the HW memory with PCIe Window method · fc5ab020
      Hariprasad Shenai authored 
      Rip out a bunch of redundant PCI-E Memory Window Read/Write routines,
collapse the more general purpose routines into a single routine
thereby eliminating the need for a large stack frame (and extra data
copying) in the outer routine, change everything to use the improved
routine t4_memory_rw.

      cxgb4: Use FW interface to get BAR0 value · 0abfd152
      Hariprasad Shenai authored 
      Use the firmware interface to get the BAR0 value since we really don't want
to use the PCI-E Configuration Space Backdoor access which is owned by the
firmware.

Set up PCI-E Memory Window registers using the true values programmed into
BAR registers.  When the PF4 "Master Function" is exported to a Virtual
Machine, the values returned by pci_resource_start() will be for the
synthetic PCI-E Configuration Space and not the real addresses. But we need
to program the PCI-E Memory Window address decoders with the real addresses
that we're going to be using in order to have accesses through the Memory
Windows work.
