From 1f69afce382f2858c825f027ed5afa97ec532f3e Mon Sep 17 00:00:00 2001 From: Antoine Tenart Date: Fri, 1 Mar 2019 11:52:17 +0100 Subject: net: mvpp2: set the GMAC, XLG MAC, XPCS and MPCS in reset when a port is down This patch adds calls in the stop() helper to ensure both MACs and both PCS blocks are set in reset when the user manually sets a port down. This is done so that we have the exact same block reset states at boot time and when a port is set down. Signed-off-by: Antoine Tenart Signed-off-by: David S.
