From 9c010ee0ea5f87438fe77132130dba0fa29e3b5d Mon Sep 17 00:00:00 2001 From: Anjali Singhai Jain Date: Thu, 28 Nov 2013 06:39:20 +0000 Subject: [PATCH] i40e: Suppress HMC error to Interrupt message level The HMC error interrupt would generate an un-necessary message "unhandled interrupt", causing extra log spam, in addition to causing a reset that was not necessary. Prevent this issue by handling the HMC error case explicitly, and only reset if the interrupt was from some of the other causes.
