Yes.  I was testing the attached patch, and when I enabled the rx-fcs, it crashed
shortly after.  So, my changes must be bad somehow...

Probably something to do with pkt_size being 4 bytes larger when
rx-fcs is enabled (I was hoping that would grab the FCS, as similar
logic seems to work fine in 8139too...)

Thanks,
Ben
