Subject[PATCH 5.0 019/115] mlxsw: spectrum_router: Do not check VRF MAC address
Date
From: Ido Schimmel <idosch@mellanox.com>

[ Upstream commit 972fae683cbad5cf348268e76abc6d55cfb3ba87 ]

Commit 74bc99397438 ("mlxsw: spectrum_router: Veto unsupported RIF MAC
addresses") enabled the driver to veto router interface (RIF) MAC
addresses that it cannot support.

This check should only be performed for interfaces for which the driver
actually configures a RIF. A VRF upper is not one of them, so ignore it.

Without this patch it is not possible to set an IP address on the VRF
device and use it as a loopback.

Fixes: 74bc99397438 ("mlxsw: spectrum_router: Veto unsupported RIF MAC addresses")
