From 6b10bfc51c494e0a2b2c0871797a1d825da9997c Mon Sep 17 00:00:00 2001 From: Antoine Tenart Date: Fri, 1 Mar 2019 11:52:11 +0100 Subject: [PATCH] net: mvpp2: always disable both MACs when disabling a port This patch modifies the port_disable() helper to always disable both the GMAC and the XLG MAC when called. At boot time we do not know of a port was enabled in the firmware/bootloader, and if so what mode was used (hence which of the two MACs was used). This also help in implementing a logic where all blocks are disabled when not used, and only enabled regarding the current mode used on a given port.
