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,
