> Using pktgen 3.6.1, I'm getting a seg fault when enabling GRE. In app/pktgen.c, on line 556 l3_hdr is set to NULL, and then on line 567 it is send to a function that calls memset on it, triggering the seg fault I'm seeing. I suppose that l3_hdr argument (and the last argument on line 569 too) should be "eth" instead?
