The solution in this case turned out to be super simple... I was
just using the wrong file. :D
It should have been /etc/sysctl.conf for the settings. Adding this
in there worked for the initial port mode setup:
# Ensure the IB card is in IB mode
sys.device.mlx4_core0.mlx4_port1="ib"
sys.device.mlx4_core0.mlx4_port2="ib"
Apologies for the noise. ;)
Regards and best wishes,
