From 5575cf133cf7f564da991595c6bc9344afa7d89a Mon Sep 17 00:00:00 2001 From: Daniel Romell Date: Fri, 19 Aug 2016 14:12:01 +0200 Subject: [PATCH] net: xilinx: emaclite: Fallback to random MAC address. If the address configured in the device tree is invalid, the driver will fallback to using a random address from the locally administered range. Signed-off-by: Daniel Romell Signed-off-by: David S.
