hack: Burst ramp up issue fix.
* Randomized payload from filler table
* 4 sps only
* 156.25 size bursts instead of 156/157
* 1 extra tail bit appended to beginning and end of burst
* Downlink bursts from core are dropped
Enable with filler table.
$ ./osmo-trx -f
Also, TSC is hard coded to 7. You can change it here.
