Subject: [PATCH net-next v2 04/16] mlxsw: spectrum_router: Ignore IPv6 multipath notifications
Date: Tue, 18 Jun 2019 18:12:46 +0300
Message-ID: <20190618151258.23023-5-idosch@idosch.org> (raw)
In-Reply-To: <20190618151258.23023-1-idosch@idosch.org>

From: Ido Schimmel <idosch@mellanox.com>

IPv6 multipath notifications are about to be sent, but mlxsw is not
ready to process them, so ignore them.

The limitation will be lifted by a subsequent patch which will also stop
the kernel from sending a notification for each nexthop.
