From 993a82b0ff03b356c0001561ca7035b02c5e7bae Mon Sep 17 00:00:00 2001 From: Murilo Fossa Vicentini Date: Wed, 19 Apr 2017 13:44:35 -0400 Subject: ibmvnic: Fix ibmvnic_change_mac_addr struct format The ibmvnic_change_mac_addr struct alignment was not matching the defined format in PAPR+, it had the reserved and return code fields swapped. As a consequence, the CHANGE_MAC_ADDR_RSP commands were being improperly handled and executed even when the operation wasn't successfully completed by the system firmware. Also changing the endianness of the debug message to make it easier to parse the CRQ content. Signed-off-by: Murilo Fossa Vicentini Signed-off-by: Nathan Fontenot Signed-off-by: David S.
