====================
net/mlx4_en: Hardware accelerated 802.1ad

This patchset by Hadar introduces support in Hardware accelerated 802.1ad, for
ConnectX-3pro NIC's.  In order to support existing deployment, and due to some
hardware limitations, the feature is disabled by default, and needed to be
enabled using a private flag in ethtool. Ofcourse user can enable the private
flag only if hardware has support.
After being enabled, the standard ethtool -k/-K can be used.

Patchset was applied and tested over commit 71790a27 ("hv_netvsc: Add structs
and handlers for VF messages")
