From 39830689ef0a935a4a2ac35c51568f483e1c5f7f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Antoine=20T=C3=A9nart?= Date: Tue, 30 Sep 2014 16:28:11 +0200 Subject: [PATCH] net: pxa168_eth: set the mac address on the Ethernet controller When changing the MAC address, in addition to updating the dev_addr in the net_device structure, this patch also update the MAC address registers (high and low) of the Ethernet controller with the new MAC. The address stored in these registers is used for IEEE 802.3x Ethernet flow control, which is already enabled. Signed-off-by: Antoine Tenart Acked-by: Arnd Bergmann Signed-off-by: David S.
