Request for assistance in modifying mfi to support LSI MegaRAID SAS 9266

[Michael Sierchio]

LSI MegaRAID SAS 9266 is not supported, the newest mentioned in the
hardware notes is the 9260.


A helpful pointer in the right direction would be welcome.  Even if no
code changes are required to support the device, I'm currently stuck
on not recognizing the device when probed.

pciconf yields

rev=0x03 hdr=0x00

    vendor     = 'LSI Logic (Was: Symbios Logic, NCR)'
    class      = mass storage
    subclass   = RAID


I am uncertain how these values map to the definitions in mfi_pci.c

struct mfi_ident {
        uint16_t        vendor;
        uint16_t        device;
        uint16_t        subvendor;
        uint16_t        subdevice;
        int             flags;
        const char      *desc;
} mfi_identifiers[] = {
        {0x1000, 0x0060, 0x1028, 0xffff, MFI_FLAGS_1078,  "Dell PERC 6"},
