From 1451ae6ef8bff77007338b2870bb3de2658afff8 Mon Sep 17 00:00:00 2001 From: Ajit Khaparde Date: Mon, 8 Oct 2012 18:18:21 +0000 Subject: [PATCH] be2net: Remove code that stops further access to BE NIC based on UE bits On certain platforms, BE hardware could falsely indicate UE. For BE family of NICs, do not set hw_error based on the UE bits. If there was a real fatal error, the corresponding h/w block will automatically go offline and stop traffic.
