From 722eef28616798dd10f9a2e4254163a5bcd54eea Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Wed, 1 Feb 2017 22:02:02 +0100 Subject: [PATCH] net: stmmac: add separate warning for PTP not being supported by HW Chips like Amlogic S905GXBB are supported by this driver but don't have support for PTP. Add a separate warning for missing HW support to differentiate it from other actual failures. Signed-off-by: Heiner Kallweit Signed-off-by: David S.
