Subject: [PATCH net-next 0/5]  qed/qede: Tunnel hardware GRO support

Hi David,

This series adds driver support for the processing of tunnel
[specifically vxlan/geneve/gre tunnels] packets which are
aggregated [GROed] by the hardware before driver passes
such packets upto the stack.

Patch 1 - General infrastructure change

Exported UDP and GRE gro_complete APIs to be revealed by driver
to complete/process hardware assisted GRO for encapsulated packets,
as gro_complete() APIs are partially exposed.
[sufficient for TCP, but not enough for udp/gre tunnels].

Patch 2/3/4 -

These patches add support for handling tunnel packets
[which are GROed by the adapter] in the driver receive data path.

Patch 5 -

This actually enables GRO functionality for tunnel packets on the adapter.

Please consider applying this series to "net-next"

Thanks,
Manish
