AFAIUI readrq size is independent and not greater than the max_payload size.
Payload size is what max a device can handle and readrq is what a device can
ask.
SIL24 does support 4096 and hence can set readrq to that limit, but if the
payload capacity of the RC is less than 4096, I am not sure if it is supposed to
work.
