From 21327f81db6337c8843ce755b01523c7d3df715b Mon Sep 17 00:00:00 2001 From: Klaus Kudielka Date: Wed, 5 Jul 2023 07:37:12 +0200 Subject: [PATCH] net: mvneta: fix txq_map in case of txq_number==1 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.
