With this patch the following two patches are backported: * bridge: fix parsing of MLDv2 reports * bridge: allow setting hash_max + multicast_router if interface is down The former one is an important fix which got just applied to the net-tree and is queued for stable. The latter is a patch which is needed to make the hash_max and multicast_router attributes configurable through netifd. Signed-off-by: Linus Lüssing <linus.luessing@c0d3.blue> SVN-Revision: 45783

Subject: [PATCH] bridge: allow setting hash_max + multicast_router if
|
|
interface is down

Network managers like netifd (used in OpenWRT for instance) try to
|
|
configure interface options after creation but before setting the
|
|
interface up.
|
|
|
|
Unfortunately the sysfs / bridge currently only allows to configure the
|
|
hash_max and multicast_router options when the bridge interface is up.
|
|
But since br_multicast_init() doesn't start any timers and only sets
|
|
default values and initializes timers it should be save to reconfigure
|
|
the default values after that, before things actually get active after
|
|
the bridge is set up.
