From 09c72ec8ed8f7499d115309a6e19cd5e66808d88 Mon Sep 17 00:00:00 2001 From: Ruben Vandeginste <snowbender@gmail.com> Date: Mon, 26 Mar 2007 14:43:49 -0700 Subject: [SUNGEM]: Fix MAC address setting when interface is up. This patch implements set_mac_address for the sungem driver. This allows changing the mac address of the interface, even when the interface is up.
