[net-next 00/15][pull request] 40GbE Intel Wired LAN Driver Updates 2016-05-01

[Jeff Kirsher]

This series contains updates to i40e and i40evf.

The theme of this series is code reduction, with several code cleanups in
this series.  Starting with Neerav's removal of the code that implemented
the HMC AQ APIs and calls, since they are now obsolete and not supported
by firmware.

Anjali changes the default of VFs to make sure they are not trusted or
privileged until its explicitly set for trust through the new NDO op
interface.  Also limited the number of MAC and VLAN addresses a VF can
add if it is untrusted/privileged.

Carolyn syncs the VF code for the changes made to the PF for the RSS
hash tuple settings, which ends up cleaning up much of the existing code.

Jesse cleans up compiler warnings which were found with gcc's W=2 option.
Then removed duplicate code, especially since only one copy was actually
being used.

Jacob addresses an issue which was found when testing GCC 6's which
happens to produce new warnings when you left shift a signed value
beyond the storage sizeof the type.  The converts i40e & i40evf to use
the BIT() macro more consistently.

Alex actually bucks the trend of code removal by adding support for
both drivers to use GSO_PARTIAL so that segmentation of frames with
checksums enabled in outer headers is supported.  Fortunately it does
not take much to add this support!

The following are changes since commit 3cfef195212976032ce7bcd6b4d0b9f1e4741725:

[net-next 02/15] i40e: Limit the number of MAC and VLAN addresses that can be added for VFs

[Jeff Kirsher]

From: Anjali Singhai Jain <anjali.singhai@intel.com>

If the VF is privileged/trusted it can do as it may please including
but not limited to hogging resources and playing unfair.
But if the VF is not privileged/trusted it still can add some number
(8) of MAC and VLAN addresses.
Other restrictions with respect to Port VLAN and normal VLAN still apply
to not privileged/trusted VF.

[net-next 03/15] i40e: Prevent falling to promiscuous if the VF is not trusted

[Jeff Kirsher]

From: Anjali Singhai Jain <anjali.singhai@intel.com>

With this change a non trusted VF can never fall to promiscuous
mode when there is no room for a MAC/VLAN filter.

[net-next 05/15] i40evf: RSS Hash Option parameters

[Jeff Kirsher]

From: Carolyn Wyborny <carolyn.wyborny@intel.com>

This patch syncs the VF code for the changes made to the PF for the RSS
hash tuple settings.  Since the VF still cannot change the RSS hash
settings, change the code to make this clear to the user.  Previously,
the default settings were returned in this function. However, the
default can be changed by the PF so this does not make sense anymore.

[net-next 06/15] i40e: Fix uninitialized variable

[Jeff Kirsher]

From: Catherine Sullivan <catherine.sullivan@intel.com>

We have an uninitialized variable warning for valid_len for one case in
validate_vf_mesg. To fix this, just initialize it to 0 at the top of the
function and remove all of the now redundant assignments to 0 in the
individual cases.

[net-next 07/15] i40e: PTP - avoid aggregate return warnings

[Jeff Kirsher]

From: Jesse Brandeburg <jesse.brandeburg@intel.com>

Aggregate return warnings are when struct types are returned
and must be copied to the lvalue with a struct copy by the compiler.

This fixes warnings of type aggregate-return from gcc with W=2.

[net-next 12/15] i40e/i40evf: fix I40E_MASK signed shift overflow warnings

[Jeff Kirsher]

From: Jacob Keller <jacob.e.keller@intel.com>

GCC 6 has a new warning which will display when you attempt to left
shift a signed value beyond the storage size of the type. I40E_MASK
generates a mask value for 32bit registers. Properly typecast the mask
value and place the values in parenthesis to prevent macro expansion
issues.

[net-next 15/15] i40e/i40evf: Add support for GSO partial with UDP_TUNNEL_CSUM and GRE_CSUM

[Jeff Kirsher]

From: Alexander Duyck <aduyck@mirantis.com>

This patch makes it so that i40e and i40evf can use GSO_PARTIAL to support
segmentation for frames with checksums enabled in outer headers.  As a
result we can now send data over these types of tunnels at over 20Gb/s
versus the 12Gb/s that was previously possible on my system.

The advantage with the i40e parts is that this offload is mostly
transparent as the hardware still deals with the inner and/or outer IPv4
headers so the IP ID is still incrementing for both when this offload is
performed.
