Title:
  VLANs no longer work with bridges in natty

Status in linux package in Ubuntu:
  Expired

Bug description:
  I'm not sure which package to put this against - it could be bridge-
  utils, vlan, linux-image-2.6.35-28-generic or possibly ifupdown. This
  problem appeared with Ubuntu 11.04 - the same configuration works
  perfectly with 10.10.

  If I use the following /etc/network/interfaces sections:
  auto br0
  iface br0 inet static
  	bridge_ports eth0
  	bridge_stp off
  	bridge_fd 0
  	bridge_maxwait 0
  	address 10.58.32.6
  	netmask 255.255.248.0
  	post-up route add -net 10.58.0.0/16 gw 10.58.32.1

  auto vlan100
  iface vlan100 inet static
  	vlan-raw-device eth0
  	address x.y.z.11
  	netmask 255.255.255.224
  	gateway x.y.z.1

  Both interfaces appear to come up, but the vlan interface cannot
  communicate - it can't even ping the gateway on its network. Changing
  the vlan-raw-device to br0 yields the same result. If I remove the br0
  section and configure eth0 directly everything works as expected.
