From cf987afc7eb182d04071bed5e2aaea8eb7d17052 Mon Sep 17 00:00:00 2001 From: Pavaluca Matei-B46610 Date: Mon, 27 Oct 2014 10:42:42 +0200 Subject: [PATCH] Add flow control support flags to gianfar's capabilities The phy device supports 802.3x flow control, but the specific flags are not set in the phy initialisation code. Flow control flags need to be added to the supported capabilities of the phydev by the driver. This is needed in order for ethtool to work ('ethtool -A' code checks for these flags) Signed-off-by: Pavaluca Matei Signed-off-by: David S.
