Subject[ 040/187] bridge: Assign rtnl_link_ops to bridge devices created via ioctl (v2)
Date
From: Greg KH <gregkh@linuxfoundation.org>

3.4-stable review patch. If anyone has any objections, please let me know.

------------------


From: stephen hemminger <shemminger@vyatta.com>

[ Upstream commit 149ddd83a92b02c658d6c61f3276eb6500d585e8 ]

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.
