I couldn't find reliable information about what this meant:
/* SUB:0 and BPSK:0 -> BPSK-20 */
/* SUB:1 and BPSK:0 -> BPSK-40 */
/* SUB:0 and BPSK:1 -> OQPSK-100/200/400 */
/* SUB:1 and BPSK:1 -> OQPSK-250/500/1000 */
None of these comments match the spec so I don't know what to put
there. If you know what these protocols are, I will immediately
provide this information into the driver and ensure the core handles
these durations properly before dropping the symbol_durations settings
from the code.
Thanks,
Miquèl
