Subject: [PATCH net] net: mvneta: fix txq_map in case of txq_number==1
Date: Wed, 5 Jul 2023 07:37:12 +0200 [thread overview]
Message-ID: <20230705053712.3914-1-klaus.kudielka@gmail.com> (raw)
If we boot with mvneta.txq_number=1, the txq_map is set incorrectly:
MVNETA_CPU_TXQ_ACCESS(1) refers to TX queue 1, but only TX queue 0 is
initialized. Fix this.
Fixes: 50bf8cb6fc9c ("net: mvneta: Configure XPS support")
