Not beyond the defaults as far as I know.  Here's the ethtool -k output:

  Offload parameters for p10p1:
  rx-checksumming: on
  tx-checksumming: off
  scatter-gather: off
  tcp-segmentation-offload: off
  udp-fragmentation-offload: off
  generic-segmentation-offload: off
  generic-receive-offload: on
  large-receive-offload: off
  rx-vlan-offload: on
  tx-vlan-offload: on
  ntuple-filters: off
  receive-hashing: off
