From 2b7beb9c0950ff032ab504a3adcabddae7bb9a01 Mon Sep 17 00:00:00 2001 From: Robert Marko Date: Thu, 24 Mar 2022 10:57:37 +0100 Subject: [PATCH] net: mvneta: add SFP TX disable handling MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Add support for handling SFP TX disable for MVNETA in the same fashion as to what MVPP2 is doing in order to enable using SFP-s. This allows using ethernet on SFP only boards.
