Subject: [PATCH net v3] net: mvpp2: Fix GoP port 3 Networking Complex Control configurations
Date: Thu, 17 Dec 2020 14:37:28 +0200 [thread overview]
Message-ID: <1608208648-13710-1-git-send-email-stefanc@marvell.com> (raw)
From: Stefan Chulski <stefanc@marvell.com>
During GoP port 2 Networking Complex Control mode of operation configurations,
