From: Ido Schimmel <ido...@mellanox.com>
The driver doesn't support events from address families other than IPv4
and IPv6, so ignore them. Otherwise, we risk queueing a work item before
it's initialized.
This can happen in case a VRF is configured when MROUTE_MULTIPLE_TABLES
is enabled, as the VRF driver will try to add an l3mdev rule for the
IPMR family.
Fixes: 65e65ec137f4 ("mlxsw: spectrum_router: Don't ignore IPv6 notifications")
