This duplicates the driver version, rather than being used for its
intended purpose, firmware version.
If firmware (or if no firmware on card, silicon) version is not
available, just use the string "n/a"

Highly likely that this needs __iomem marking, and potentially
additional attention.

Seems like you could eliminate the branches with power-of-2 + masks.

Problems:
1) bitfields are not endian-clean
2) it's silly to use bitfields of sizes 8, 16, and 32. This generates
grossly sub-optimal code compared to use of u8, u16, u32 C types.
3) Most likely you should be using __le32, etc.

why do you need these defines at all? Device IDs used on only one place
can normally just be directly coded as a numeric hexidecimal constant.

overall, enums are preferred over #define. It provides type info to the
compiler, provides symbol info to debuggers and similar tools, and other
benefits.
e.g.
enum {
NETXEN_HW_RPMX9_CRB_AGT_ADR = 0x12,
NETXEN_HW_SMB_CRB_AGT_ADR = 0x18,
};

1) two functions for such a simple task is overkill
2) just create separate hooks for GBE and XGBE, and eliminate these
wrapper functions that do nothing but "switch (adapter->ahw.board_type)"
before calling board-specific functions.
