EM driver options not working
0%
Description
- 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 ?

My bad I've explained the problem not correctly :
This are unchecked, the options should be activated on interface (LRO, TSO, ...), but are not :- Disable hardware checksum offload (unchecked)
- Disable hardware TCP segmentation offload (unchecked)
- Disable hardware large receive offload (unchecked)
Could you reopen, thanks.
