atl1c: fix tx timeout after link flap on Mikrotik 10/25G NIC

Gatis Peisenieks · kuba-moo · commit bf8e59fd315f · 2022-02-11T14:41:02.000-08:00
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.
