As Sylvain explained on irc having modulo and frame number bigger than 256 might be
useful for experimentation with packets which are spread across several frames - to
represent them as huge 'fake' multiframe.
At least that's how I've understood it. He's surely doing some creepy magic
with GSM :-)

On ARM, it doesn't matter. even if you made those
fields uint8_t
in the struct mframe_sched_item, they would still be aligned to 32bit
boundaries. So you wouldn't change the memory layout at all based on
your change.
That's odd - after I've changed it to uint8_t the
"board/compal_e88/rssi.compalram.elf section `.data' will not fit in region
`LRAM'"
error is gone. I'm no expert in compiler internals but I think that indicates the
change in memory layout.
Could you please comment?
Given that the CPU speed is more limited than RAM, I
think the current
approach makes sense.
I agree.
Is it possible
for 'modulo' to be bigger than 255?
I don't think so, at least not for standard GSM operation.
