[Intel-wired-lan] [next PATCH S51-V2 0/8] i40e/i40evf updates

[Bimmy Pujari]

Alexander Duyck adds code to be much more verbose about what we can and 
cannot offload.

Jacob Keller removes unnecessary label from
i40e_vc_config_promiscuous_mode_msg, removes second check of VLAN_N_VID
in i40e_vlan_rx_add_vid, adds code to avoid duplicate private flags
definitions & fixes trivial typo in naming of i40e_sync_filters_subtask.

Michal Kosiarz adds code for Clause22 implementation.

Piotr Raczynski adds code to add protocols over MCTP to 
i40e_aq_discover_capabilities.

[Intel-wired-lan] [next PATCH S51-V2 1/8] i40e: Be much more verbose about what we can and cannot offload

[Bimmy Pujari]

From: Alexander Duyck <alexander.h.duyck@intel.com>

This change makes it so that we are much more robust about defining what we
can and cannot offload.  Previously we were just checking for the L4 tunnel
header length, however there are other fields we should be verifying as
there are multiple scenarios in which we cannot perform hardware offloads.

In addition the device only supports GSO as long as the MSS is 64 or
greater.  We were not checking this so an MSS less than that was resulting
in Tx hangs.

Testing Hints:
        This is half of the fix needed to address MSS less than 64.  This
        is the fix for upstream and kernels after 3.18.4, but we will need
        to come up with a separate fix for out-of-tree that can be stripped
        on kernels prior to 3.18.4.

        An easy test for this patch is to just set the MTU for an interface
        to a value 102.  Without this patch we should see Tx hangs with
        netperf and with we should be able to pass traffic without
        triggering Tx hangs.

From: Alexander Duyck <alexander.h.duyck@intel.com>

This change makes it so that we are much more robust about defining what we

should bring us up to parity with the i40e PF driver.

In addition the device only supports GSO as long as the MSS is 64 or

in Tx hangs.

[Intel-wired-lan] [next PATCH S51-V2 3/8] i40e: remove error_param_int label from i40e_vc_config_promiscuous_mode_msg

[Bimmy Pujari]

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

This label is unnecessary, as are jumping to a block that checks aq_ret
and then immediately skipping it and returning. So just jump straight to
the error_param and remove this unnecessary label.

Also use goto error_param even in the last check for style consistency.

[Intel-wired-lan] [next PATCH S51-V2 5/8] i40e: avoid duplicate private flags definitions

[Bimmy Pujari]

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

Separate the global private flags and the regular private flags per
interface into two arrays. Future additions of private flags will not
need to be duplicated which may lead to buggy code. Also rename
"i40e_priv_flags_strings_gl" to "i40e_gl_priv_flags_strings" for
clarity, as it reads more naturally.
