Subject: [PATCH] net: bridge: locally receive all multicast packets if
|
|
IFF_ALLMULTI is set
|
|
|
|
If multicast snooping is enabled, multicast packets may not always end up on
|
|
the local bridge interface, if the host is not a member of the multicast
|
|
group. Similar to how IFF_PROMISC allows all packets to be received locally,
|
|
let IFF_ALLMULTI allow all multicast packets to be received.
