Hi Florian,
I've been assigned this new bug which is a clone of Bug 1058544. I'm updating the Performance Tuning Guide, and was wondering if the patch you created needs documenting, or whether it's more of a background thing that the user doesn't really need to know about? Thanks in advance.

Chalie Boyle.

Its pure bug fix, user should not need to care about it.
If you created VLAN device on a bridge, then vlan disabled a lot of features because bridge device did not expose them. So depending on the netdevice features that are available on the bridge, the vlan device may have more of the existing features available/enabled now and thus allows for higher throughput/less cpu
cycles.
