Re: [patch net-next 10/10] mlxsw: spectrum_router: Don't abort on l3mdev rules

From: Ido Schimmel <redacted>

Now that port netdevs can be enslaved to a VRF master we need to make
sure the device's routing tables won't be flushed upon the insertion of
a l3mdev rule.

Note that we assume the notified l3mdev rule is a simple rule as used by
the VRF master. We don't check for the presence of other selectors such
as 'iif' and 'oif'.
