[-- Attachment #1 --] I have the following situation: bce0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=1bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4> ether 00:14:5e:6d:2d:74 media: Ethernet autoselect (1000baseSX <full-duplex>) status: active vlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=3<RXCSUM,TXCSUM> ether 00:14:5e:b3:2a:38 inet xx.xx.xx.xx netmask 0xffffff00 broadcast xx.xx.xx.255 media: Ethernet autoselect (1000baseSX <full-duplex>) status: active vlan: 250 parent interface: bce1 e.g. the network card is directly on a trunked network, and I have the vlan interface with actual IP address. My question is: since this setup mixes various network&protocol layers, are the TSO capabilities of the card used? I guess not and that only RXCSUM & TXCSUM are used (for IP-level packets).
