Subject: [PATCH net-2.6] bnx2: Always set ETH_FLAG_TXVLAN
Date: Mon, 24 Jan 2011 14:59:02 -0800 [thread overview]
Message-ID: <1295909942-758-1-git-send-email-mchan@broadcom.com> (raw)
TSO does not work if the VLAN tag is in the packet (non-accelerated).
We may be able to remove this restriction in future firmware.
