Subject: mlxsw: spectrum_switchdev: Remove mrouter flood in mdb flush
Patch-mainline: v4.15-rc1
Git-commit: 0166277706e57779f06b741d25a9e86d99726e2a
References: bsc#1112374

In mdb flush the port is being removed from all the mids it is registered
to. But if the port is mrouter, all the mids floods to it.
This patch remove mrouter ports from mids it is not registered to in the
mdb flush.
