ice: optimize for XDP_REDIRECT in xsk path

Browse source

[ Upstream commit bb52073645 ]

Optimize ice_run_xdp_zc() for the XDP program verdict being
XDP_REDIRECT in the xsk zero-copy path. This path is only used when
having AF_XDP zero-copy on and in that case most packets will be
directed to user space. This provides a little over 100k extra packets
in throughput on my server when running l2fwd in xdpsock.
