Okay, so next noob question (and applies to the jolly branch)

msg->data[0] = (msg->data[0] & 0xf8) | usf;

in the above it is possible that !poll_tbf and usf == 0x7, is
this the right behavior in case no TBF could be found?

PS: NOOB
question, what is the meaning of USF==0x7?
This is a special value which in means "free", i.e. it's not allocated
to any mobile if we use dynamic allocation (IIRC). And if we use PRACH
channel instead of RACH, then USF 7 is used to mark places for Access
Bursts.
