Merge branch 'bpf-xdp-remove-xdp-flush'
Jesper Dangaard Brouer says:
====================
This patchset removes the net_device operation ndo_xdp_flush() call.
This is a follow merge commit ea9916ea3ed9 ("Merge branch
'ndo_xdp_xmit-cleanup'"). As after commit c1ece6b245bd ("bpf/xdp:
devmap can avoid calling ndo_xdp_flush") no callers of ndo_xdp_flush
are left in bpf-next tree.
