ice: optimize for XDP_REDIRECT in xsk path
stable inclusion from stable-5.10.43 commit 9e1eb428849fab331c73876be4a52bbcf884dbb0 bugzilla: 109284 CVE: NA -------------------------------- [ Upstream commit bb520736 ] 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.
