From 6819563e646a7f3692836daefd12cd86c697759f Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Fri, 19 Sep 2014 13:07:54 -0700 Subject: [PATCH] net: dsa: allow switch drivers to specify phy_device::dev_flags Some switch drivers (e.g: bcm_sf2) may have to communicate specific workarounds or flags towards the PHY device driver. Allow switches driver to be delegated that task by introducing a get_phy_flags() callback which will do just that. Signed-off-by: Florian Fainelli Signed-off-by: David S.
