From 692783980ad6163e8586baa36c066cd0d22fc7ce Mon Sep 17 00:00:00 2001 From: Shannon Nelson Date: Thu, 10 Mar 2016 14:59:43 -0800 Subject: [PATCH] i40e: Remove MSIx only if created When cleaning up the interrupt handling, clean up the IRQs only if we actually got them set up. There are a couple of error recovery paths that were violating this and causing the kernel a bit of indigestion.
