From 5434e8faf05a3a9514b0a3698245764780be41e0 Mon Sep 17 00:00:00 2001 From: Antoine Tenart Date: Fri, 1 Mar 2019 11:52:15 +0100 Subject: net: mvpp2: reset the MACs when reconfiguring a port This patch makes sure both PPv2 MACs (GMAC + XLG MAC) are set in reset while a port is reconfigured. This is done so that we make sure a MAC is in a reset state when not used, as only one of the two will be set out of reset after the port is configured properly.
