Add InfiniBand NDR 400 Gbps port type

Proposed functionality

ur QM9700 1U NDR 400Gbps InfiniBand Switch System (https://docs.nvidia.com/networking/display/qm97x0pub/introduction) has 64 ports with NDR 400Gbps, so we would like to have added the options "NDR (400 Gbps)" to the choice list for the Interface Type. Something like

TYPE_INFINIBAND_NDR = 'infiniband-ndr-400' (TYPE_INFINIBAND_NDR, 'NDR (400 Gbps)'),

in the https://github.com/netbox-community/netbox/blob/main/netbox/dcim/choices.py

I am not sure, if these settings is enough or there are anywhere else, which will need to get a change for it to work.

Use case

For now we have only the options to select "NDR (100 Gbps)" , which is not ideal as the port on the Nvidia switch is "NDR (400 Gbps)", so we would like to have this option added to the Netbox, so we have a clear picture of our servers and swithces.

If implementing needs to double-check the spec and do some research, confirm that this is for multi-channel implementation of NDR (4 x 100 Gig) and not GDR.

Hi Arthur

I had a little vacation and just saw this email now. I can confirm, that it is a multi-channel implementation of NDR (4 x 100 Gig).

Bets regards, Jørn Jensen UCPH
