Sathya Perla says:

====================
be2net: add vxlan offload support

The first patch adds the FW cmds needed to configure the Skyhawk-R
chip for supporting VxLAN offloads. The second patch implements the
ndo_add/del_vxlan_port() methods and the plumbing for supporting
RX/TX csum, TSO and RSS steering offloads for VxLAN traffic.

v2 changes:
NETIF_F_SG need not be set for hw_enc_features by the driver as it is
done by the stack.

v3 changes:
* Defer FW cmds needed for VxLAN offloads to a workqueue
* Reset FW to VxLAN offloads disabled state in the unload path

v4 changes:
* Revert the usage of workqueue (introduced in v3) to implement
ndo_add/del_vxlan_port() as it is currently not needed (none of the
FW cmd calls sleep.) Suggested by David M.
