Err, that is not right. I was looking at pkts originating on the interface, not the ones being received. So, while rx-all works fine, packets with good or bad fcs still do not have the FCS bytes properly appended. I'm going to go poke at the e1000 VLAN thing now, but let me know if you see problems with my igb patch or have other suggestions..it should be quick for me to do some testing.
