From 197d67f1225e31f8a3572aef93613c0702ee61a7 Mon Sep 17 00:00:00 2001 From: Jussi Kivilinna Date: Tue, 10 Jan 2012 06:40:17 +0000 Subject: [PATCH] asix: fix setting custom MAC address on Asix 88772 devices commit 8ef66bdc4bda6aac2dae73b84d79dc8c2db33637 upstream. In kernel v3.2 initialization sequence for Asix 88772 devices was changed so that hardware is reseted on every time interface is brought up (ifconfig up), instead just at USB probe time. This causes problem with setting custom MAC address to device as ax88772_reset causes reload of MAC address from EEPROM. This patch fixes the issue by rewriting MAC address at end of ax88772_reset.
