Date: Tue, 22 Feb 2011 00:29:02 +0100 From: Jan Niehusmann <jan@...dor.com> To: linux-kernel@...r.kernel.org Cc: netdev@...r.kernel.org Subject: TX VLAN acceleration on bridges broken in 2.6.37? With the following configuration, sending vlan tagged traffic from a bridged interface doesn't work in 2.6.37. The same configuration does work with 2.6.36: - bridge br0 with physical interface eth0 - eth0 being an e1000e device (don't know if that's important) - vlan interface br0.10 - (on 2.6.37) tx vlan acceleration active on br0 (default) Networking on br0.10 doesn't work, and tcpdump on eth0 shows packets sent on br0.10 as untagged, instead of vlan 10 tagged. After turning vlan tx offloading off with 'ethtool -K br0 txvlan off', everything works as expected, again. The workaround is made permanent by reverting "bridge: Add support for TX vlan offload.", 361ff8a6cf90d62c0071b7e532e37369bfd3ae77, turning of the feature on bridges completely.
