From eb0eecc136c917053c2e1b7eac8b8e8e2ebb3e6c Mon Sep 17 00:00:00 2001 From: Somnath Kotur Date: Wed, 12 Feb 2014 16:07:54 +0530 Subject: [PATCH] be2net: Log a kernel message when UE is detected in BE & Skyhawk This patch logs a kernel message when a HW error(SLIPORT_ERROR in Lancer and UE in BEx/Skyhawk) is detected. The log message for BE3 was missing earlier. This patch also refactors the code by segregating error-detection and reporting code for Lancer and BEx/SH.
