Hi all,

After merging the bpf-next tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

ERROR: ".xsk_reuseq_swap" [drivers/net/ethernet/intel/i40e/i40e.ko] undefined!

Caused by commit

  9654bd10da60 ("i40e: clean zero-copy XDP Rx ring on shutdown/reset")

CONFIG_XDP_SOCKETS is not set for this build.

I have used the version of the bfp-next tree from next-20180906 for today.

merge conflict and build error...
Bjorn, I'm thinking to toss the patches out of bpf-next and reapply
cleaned up version of the patches...
what do you think?
