From c8e1e82b6a97ad44517517aa58b7b794ead0bf33 Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Sat, 29 Apr 2006 18:55:17 -0700 Subject: [TG3]: Call netif_carrier_off() during phy reset Add netif_carrier_off() call during tg3_phy_reset(). This is needed to properly track the netif_carrier state in cases where we do a PHY reset with interrupts disabled. The SerDes code will not run properly if the netif_carrier state is wrong.
