From 5055d2f236e1495d68c468eeb684fd5789673f1d Mon Sep 17 00:00:00 2001 From: Danny Kukawka Date: Thu, 16 Feb 2012 07:09:31 +0000 Subject: [PATCH] adi: adapt to eth_hw_addr_random() and changes in arch/blackfin Adapt adi ethernet driver to changes in bfin_get_ether_addr() from arch/blackfin. bfin_get_ether_addr() returns now a state. Set a random mac address via new eth_hw_addr_random() in case the return value is not 0. Reset the state to NET_ADDR_PERM as soon as the MAC get changed via .ndo_set_mac_address. v2: change the logic to reduce unneeded checks Signed-off-by: Danny Kukawka Signed-off-by: David S.
