Add BPF extension SKF_AD_PKTTYPE to ppc JIT to load

if you'd only quoted #12, it would all make sense ;)
but #11 test is not using PKTTYPE. So your patch shouldn't
make a difference. Are these numbers with JIT on and off?
Right.
Ok.
Please mention this in future log messages, as it was not quite
clear that "before" was actually with JIT off, and "after" was
with JIT on.
One could have read it that actually both cases were with JIT on,
and thus the inconsistent result for LD_IND_NET is a bit confusing
since you've quoted it here as well.
