From c6e429bdd6f0142558896e29c21a526c1ffdd1f3 Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Wed, 23 Nov 2005 12:49:55 +0100 Subject: [PATCH] [PATCH] pm3386: implement reset Implement pm3386 reset. A reset zeroes out the internally stored MAC addresses, so we need to save and reload them by hand.
