The white lists control the issuing/checking of several Mellanox vendor
specific MADs such as SM class MLNX ExtendedPortInfo (MEPI) which
handles FDR10 and vendor class 0x0A GeneralInfo interpretation as to
whether extended version fields are supported.

It will affect FDR10 reporting or version reporting done via Mellanox
vendor specific MADs.

Do you see any that you think are missing ?

To know whether MEPI can be issued or not without timeout and to
properly interpret the version fields in the GeneralInfo response.
