Subject: [patch net-next v3 12/12] rocker: Register FIB notifier before creating ports

From: Ido Schimmel <idosch@...lanox.com>

Unlike mlxsw, rocker only supports the reflection of routes pointing to
its own netdevs. Therefore, instead of requesting a FIB dump during
init, simply register the FIB notifier before creating the ports.
