From: Kalesh AP <kalesh-anakkur.pura...@broadcom.com>
VFs and multifunction PFs do not have the privilege to change
link configuration. We force the physical link down as a part
of device stop only for single physical function(SPF).
This change also helps in eliminating the logs when a VF port
is stopped:
"Port 0: link state change event"
"bnxt_print_link_info(): Port 0 Link Up - speed 25000 Mbps - full-duplex"
