From: Maher Sanalla <msanalla@nvidia.com>

NDR(106.25 Gbps) support exposed new data rates:
800 Gbps - NDR 8x.
1200 Gbps - NDR 12x.

The NDR support bit from PortInfo.CapabilityMask2 was added to libibmad
as well as the new link speeds mentioned above.

validate_extended_speed() function in infiniband-diags was adjusted to
validate NDR speed.

Reference: IB Spec Release 1.5
