Just as a follow-up to let future readers know what I did.

No problem, that was provided more for context of what I am doing.
Which I already had the radiotap portion written.

So looking that the set_txpower for each type of eeprom, they
apparently do basically the same thing except for the 9003_eeprom.
Just before writing the rate power array, it iterates over the array
doing a -= {factor} * 2 where factor is either a define with a value
of -5 or the value in EEP_PWR_TABLE_OFFSET. For the 9285 I deal with
that has an 4k eeprom (which uses a define for the factor),
EEP_PWR_TABLE_OFFSET also has a value of -5. So I just went with using
EEP_PWR_TABLE_OFFSET * 2 for my offset, but will have to do something
more complicated when I have to start dealing with cards using the
9003_eeprom.
