Thanks.  For reference:

 commit 149ddd83a92b
 Author: stephen hemminger <shemminger@vyatta.com>
 Date:   Tue Jun 26 05:48:45 2012 +0000

     bridge: Assign rtnl_link_ops to bridge devices created via ioctl (v2)

     This ensures that bridges created with brctl(8) or ioctl(2) directly
     also carry IFLA_LINKINFO when dumped over netlink. This also allows
     to create a bridge with ioctl(2) and delete it with RTM_DELLINK.

This is in the netdev stable queue[1] so it should be part of upstream
stable kernels soonish.

Can you say a little more about the background?  Is this a regression?
What kernel versions are affected?  Is this going to create trouble
during squeeze → wheezy upgrades for people upgrading userspace before
the kernel or vice versa?

Hope that helps,
