[PATCH net] atl1c: fix tx timeout after link flap on Mikrotik 10/25G NIC

From: Gatis Peisenieks
Date: Thu Feb 10 2022 - 03:47:43 EST


If NIC had packets in tx queue at the moment link down event
happened, it could result in tx timeout when link got back up.

Since device has more than one tx queue we need to reset them
accordingly.
