>Description:

Adding an physical network interface to a created bridge prevents outgoing
trafic on that interface. Bridging between the interfaces added to the bridge
still works.

Confirmed to still work correctly on 4.99.72 with the vr0 interface.

 Found cure and most likely the cause. The bridge starts working if i disable
 the interface's hardware acceleration.
