[dpdk-dev] [PATCH] net/i40e: enable dst MAC address as FDIR input set

FVL enable Destination MAC address as FDIR's input set for
ipv4-other. When OVS-DPDK is working as a pure L2 switch,
destination MAC match offload with Mark+RSS action would help
the performance speed up. And FVL FDir supports to change input
set to be destination MAC.
