I don't see any print connected to the Uplink TBF

I don't understand that part? What happens here is that we poll for
a PACKET CONTROL ACK. So we know the TBF based on the FN. And in this
TBF we notice that the TLLI has changed (ACK is using the new TLLI
that is derived from the P-TMSI).
(what bts->tbf_by_tlli(m_tlli, GPRS_RLCMAC_UL_TBF)
returns?). Corresponding
to TS 04.60, 11.2.29 Packet Uplink Assignment possibly may use DL TFI to
address the MS in place of TLLI (we still don't know if it's accepted or
not by MS). Also the uplink FN may be used to find corresponding UL TBF
context (according to Packet Uplink Assignment RRBP field) for UL Packet
Control Ack which contains relevant TLLI. So is it really necessary to
link UL and DL TBFs in the case? ...
