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
