From 00eb2243b933a496958f4ce1bcf59840fea8be16 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Wed, 12 Sep 2018 01:53:12 +0200 Subject: [PATCH] net: bcmgenet: Fix speed selection for reverse MII The phy supported speed is being used to determine if the MAC should be configured to 100 or 1G. The masking logic is broken. Instead, look at 1G supported speeds to enable 1G MAC support. Signed-off-by: Andrew Lunn Acked-by: Florian Fainelli Signed-off-by: David S.
