Sriharsha Basavapatna 627c89d00f bnxt_en: flow_offload: offload tunnel decap rules via indirect callbacks
The decap (VXLAN tunnel) flow rules are not getting offloaded with
upstream kernel. This is because TC block callback infrastructure has
been updated to use indirect callbacks to get offloaded rules from
other higher level devices (such as tunnels), instead of ndo_setup_tc().
Since the decap rules are applied to the tunnel devices (e.g, vxlan_sys),
the driver should register for indirect TC callback with tunnel devices
to get the rules for offloading. This patch updates the driver to
register and process indirect TC block callbacks from VXLAN tunnels.
