From 28f4d16570dcf440e54a4d72666d5be452f27d0e Mon Sep 17 00:00:00 2001 From: Thomas Falcon <tlfalcon@linux.vnet.ibm.com> Date: Wed, 15 Feb 2017 10:32:11 -0600 Subject: [PATCH] ibmvnic: Fix endian error when requesting device capabilities When a vNIC client driver requests a faulty device setting, the server returns an acceptable value for the client to request. This 64 bit value was incorrectly being swapped as a 32 bit value, resulting in loss of data. This patch corrects that by using the 64 bit swap function.
