Subject: [PATCH net] atl1c: fix tx timeout after link flap on Mikrotik 10/25G NIC
Date: Fri, 11 Feb 2022 08:51:23 +0200 [thread overview]
Message-ID: <20220211065123.4187615-1-gatis@mikrotik.com> (raw)
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.
Fixes: 057f4af2b171 ("atl1c: add 4 RX/TX queue support for Mikrotik 10/25G NIC")
