From 0b85c0ebde63a41d57b6214977ac2752bf5a086f Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Wed, 23 Nov 2005 12:49:47 +0100 Subject: [PATCH] [PATCH] pm3386: add hook for setting MAC address When we reset the pm3386, it loses its internally stored MAC addresses that were programmed into it by the bootloader (and are used by the hardware for the generation of PAUSE frames.) Add a hook to allow setting these addresses so that we can program them back by hand.
