From fcf99ac631b61e6937ed10cd1b53a5b3dab29052 Mon Sep 17 00:00:00 2001 From: Jussi Kivilinna Date: Tue, 10 Jan 2012 06:40:23 +0000 Subject: [PATCH] asix: fix setting custom MAC address on Asix 88178 devices commit 71bc5d94061516c4e70303570128797bcf768b10 upstream. In kernel v3.2 initialization sequence for Asix 88178 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 ax88178_reset causes reload of MAC address from EEPROM. This patch fixes the issue by rewriting MAC address at end of ax88178_reset.
