Add BPF extension SKF_AD_PKTTYPE to ppc JIT to load
skb->pkt_type field.

Before:
[   88.262622] test_bpf: #11 LD_IND_NET 86 97 99 PASS
[   88.265740] test_bpf: #12 LD_PKTTYPE 109 107 PASS

After:
[   80.605964] test_bpf: #11 LD_IND_NET 44 40 39 PASS
[   80.607370] test_bpf: #12 LD_PKTTYPE 9 9 PASS

v2: Added test rusults

So, can I apply this now?

I think this question is more towards ppc folks,
since both Daniel and myself said before that it looks ok.

Yeah sorry, as I said I don't really know enough about BPF to ack it.

Philippe just tested the previous version of this patch on ppc64le...
I'm guessing that Matt (original author of bpf jit for ppc) is not replying,
because he has no objections.

Actually that might be because he works at ARM now :)

If you can CC Philippe on future BPF patches for powerpc that would probably
help.

cheers
