Firmware releases follow a "Core N" pattern, but due to some historical accidents, the API number for a Core N has always been N+3. That's confusing for everyone. For future firmware releases the firmware will make new file names that, instead of being named with the API number, will be named with the core number. For example, for the next one for bz/fm it'd be "iwlwifi-bz-b0-fm-c0-c99.ucode" instead of the now expected "iwlwifi-bz-b0-fm-c0-102.ucode". In the driver, represent that as an offset of 1000, and then request the "c<core>" format instead of just "<api>". When looking for older versions, skip from 1099 to 101 (which is core 98.)
