Re: [PATCH 24/27] qtnfmac: configure and start AP interface with a single command

This separation would not allow to do a proper device configuration as
first stage needs to use information from IEs that are processed on
a second stage. Which means first and second stages have to be meged.
In that case there is no point anymore to keep third stage either, so
merge all three into a single command.

typo in commit message: 'meged'

Initial len value is sizeof(struct qlink_cmd_start_ap), qlink_cmd is a part
of qlink_cmd_start_ap. So this check has to be fixed. It looks like the
simplest option is only to check payload: set initial len value to 0
and drop sizeof in comparison.
