- ssb: sprom: add dev_id field for value overriding standard ID
-
- Some devices may have different features despite sharing the same ID
- (e.g. PCI ID). For example 14e4:4331 is usually a dual band, but this
- can be "limited". Device with "pci/x/y/devid=0x4332" supports 2.4 GHz
- only. Similarly 0x4333 will mean support for 5 GHz only.
- Add entry in SPROM so info described above can be extracted and stored.
