All errors (new ones prefixed by >>):

    In file included from <command-line>:
    net/core/filter.c: In function '____bpf_xdp_redirect_xsk':
net/core/filter.c:4165:35: error: 'struct netdev_rx_queue' has no member named 'xsk'

This rev is missing proper CONFIG_XDP_SOCKET ifdefs. I'll fix this in
the next spin, but I'll wait a bit for more comments.
