From bb900b27a2f49b37bc38c08e656ea13048fee13b Mon Sep 17 00:00:00 2001 From: stephen hemminger Date: Mon, 4 Apr 2011 14:03:32 +0000 Subject: bridge: allow creating bridge devices with netlink Add netlink device ops to allow creating bridge device via netlink. This works in a manner similar to vlan, macvlan and bonding. Example: # ip link add link dev br0 type bridge # ip link del dev br0 The change required rearranging initializtion code to deal with being called by create link. Most of the initialization happens in br_dev_setup, but allocation of stats is done in ndo_init callback to deal with allocation failure. Sysfs setup has to wait until after the network device kobject is registered. Signed-off-by: Stephen Hemminger Signed-off-by: David S.
