Yep Full-Duplex on both and these are what the offload parameters look
like
Offload parameters for eth2:
rx-checksumming: on
tx-checksumming: on
scatter-gather: on
tcp segmentation offload: on
udp fragmentation offload: off
generic segmentation offload: off
Since it's lot of little packets I left udp frag seg off because I
didn't think it would be of much use.
