patch to fix pkt-gen

From: John-Mark Gurney <>

pkt-gen by default compiles against headers that it ships with.  This is
likely to deal w/ Linux, but now that FreeBSD has rev'd the API a few
times, it fails to work on FreeBSD, instead, giving you this:
360.000574 [ 376] netmap_ioctl_legacy       Minimum supported API is 14 (requested 11)

This drops the inclusion of the header files when building pkt-gen,
so that it uses the correct FreeBSD kernel headers.

I have done basic testing, and pkt-gen is working.

Note, that this does not update pkt-gen to the latest in github, and it is
almost 4 years out of date.

I can commit it (I think, I haven't used a ports bit in years) if
someone wants to approve it, or someone else can commit it for me.

I have included it both inline and attached, in case there are problems
w/ either.
