Subject: [PATCH 1/6] ibmvfc: byte swap login_buf.resp values in attribute show functions

From: Tyrel Datwyler <[email-masked]>
Date: Wed, 11 Nov 2020 19:04:37 -0600

Both ibmvfc_show_host_(capabilities|npiv_version) functions retrieve
values from vhost->login_buf.resp buffer. This is the MAD response
buffer from the VIOS and as such any multi-byte non-string values are in
big endian format.

Byte swap these values to host cpu endian format for better human
readability.
