From c922d1241ff37ab2db0f1a29e4b043fe1d8a8e8c Mon Sep 17 00:00:00 2001 From: Mark Einon Date: Tue, 23 Aug 2011 23:40:38 +0100 Subject: [PATCH] staging: et131x: Fix link detection signalling Remove redundant code around netif_carrier_XXX calls, and associated adapter->media_state, which prevented the link from being reported as off. Tested on an ET-1310 device.
