Patch adding vlan support to network-bridge-bonding

Description of problem:

when bonding + 802.1q vlans are configured, network-bridge-bonding won't be able to get vlan interfaces up properly because script does ifdown to vlan interfaces.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. configure bonding over ethernet interfaces
2. configure 802.1q over bonding
3. make wrapper script to get several network bridges with network-bridge-bonding
Actual results:
Only bond0 bridge comes up. bond0.5 and other vlan over bond devices vanish because network-bridge-bonding run ifdown against them which removes vlan device.

Expected results:

pbond0.5 device and bond0.5 bridge.

Additional info:

Wrapper script used:

# /etc/xen/scripts/network-script-local, wrapper for multiple bridges
dir=$(dirname $0)
$dir/network-bridge-bonding $@ netdev=bond0 bridge=bond0
$dir/network-bridge-bonding $@ netdev=bond0.5 bridge=bond0.5
Comment 3 Tuomo Soini 2009-04-27 02:38:24 EDT
There is needinfo requested. Is there any additional info needed?
Comment 4 Bryan Mason 2009-04-27 14:53:51 EDT
The needinfo request was actually intended for some of the Red Hat developers.
