Description

pfSense Advanced options :
  • Disable hardware checksum offload
  • Disable hardware TCP segmentation offload
  • Disable hardware large receive offload

Ifconfig provide the following
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=4209b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_MAGIC,VLAN_HWTSO>
em1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=4009b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,VLAN_HWTSO>
em2: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=4209b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_MAGIC,VLAN_HWTSO>

Hardware checksum offload seem to be working, but lro and tso are not activated.

Interfaces are the following :
  • em0-1: Intel PRO/1000 PT Dual-Port
  • em2: Intel PRO/1000

All 2 cards supports LRO and TSO, so the options should be activate ?
