From 3f007891da0ad3d9192e9aa13ce4e3aaf20c33fa Mon Sep 17 00:00:00 2001 From: Matt Carlson Date: Mon, 3 Nov 2008 16:51:36 -0800 Subject: [PATCH] tg3: Preserve LAA when device control is released This patch moves the __tg3_set_mac_addr() function earlier in the file listing, to avoid a function prototype, and calls the function to restore the LAA after a driver unload chip reset. With this code in place, the administrator can wake the machine using the LAA. Signed-off-by: Matt Carlson Signed-off-by: Michael Chan Signed-off-by: David S.
