Just curious if anyone out there is currently using the "nic" gres type and
how do you deal with the fact that the Files= entry in gres.conf has to refer
to an existing device when network devices generally don't appear under /dev?
Do you just hack with with "touch" or "mkdev" ?
The bug that introduced the code was:
and the example given was:
Name=nic File=/dev/mlx4_0 CPUs=0-1
Name=nic File=/dev/mlx4_1 CPUs=2-3
but nothing like those names will exist with Mellanox OFED.

mlx5_1 port 1 ==> p1p2 (Up)
mlx5_2 port 1 ==> p2p1 (Down)
mlx5_3 port 1 ==> p2p2 (Down)
