H A Dfw.h0d49eaf4 Thu Dec 14 23:29:18 CST 2017 Jakub Kicinski <jakub.kicinski@netronome.com> nfp: bpf: add basic support for adjust head call

Support bpf_xdp_adjust_head(). We need to check whether the
packet offset after adjustment is within datapath's limits.
We also check if the frame is at least ETH_HLEN long (similar
to the kernel implementation).
