This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enig53B232959B3629782EC19C8E Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable I have the following situation: bce0: flags=3D8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=3D1bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSU= M,TSO4> ether 00:14:5e:6d:2d:74 media: Ethernet autoselect (1000baseSX <full-duplex>) status: active vlan0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu = 1500 options=3D3<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). --------------enig53B232959B3629782EC19C8E Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFI82iMldnAQVacBcgRAoL6AKCOKwwVot9/3t9kK9kQ/brkRGW1XwCfcmUx W41cE83f9iyD9cHLLHg+rAk= =+gVa -----END PGP SIGNATURE----- --------------enig53B232959B3629782EC19C8E--
