    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.
