From 0775437293a6963cb21244dfae6978cbf67c6bfe Mon Sep 17 00:00:00 2001 From: Ben Warren Date: Wed, 21 Oct 2009 21:53:39 -0700 Subject: [PATCH] Fix DM9000 MAC address handling Proper behavior is to pull MAC address from NVRAM in the initialization() an stuff it in dev->address, then program the device from dev->address in the init() function.
