From 0d8e14392f7697e5ee241d49fce3355f22406d3e Mon Sep 17 00:00:00 2001 From: Anjali Singhai Jain Date: Fri, 5 Jun 2015 12:20:32 -0400 Subject: [PATCH] i40e: Add IWARP support for X722 X722 supports IWARP, this patch handles checking for PE critical errors. Since the driver doesn't support the IWARP interface for now, this patch just does bare minimum to log a message oif a PE critical error happens.
