In MegaRaid we have below enum -        VENTURA_SERIES and AERO_SERIES
supports NVME

enum MR_ADAPTER_TYPE {
        MFI_SERIES = 1,
        THUNDERBOLT_SERIES = 2,
        INVADER_SERIES = 3,
        VENTURA_SERIES = 4,
        AERO_SERIES = 5,
};

In mpt3sas driver we have below method - If IOC FACT reports NVME Device
support in Protocol Flags, we can consider it as HBA with NVME drive
support.

ioc->facts.ProtocolFlags & MPI2_IOCFACTS_PROTOCOL_NVME_DEVICES
