Attention is currently required from: osmith. Hello osmith, Jenkins Builder,

I'd like you to reexamine a change. Please visit

https://gerrit.osmocom.org/c/osmo-pcu/+/29905

to look at the new patch set (#3).

Change subject: Delay ImmAss(PCH, PktDlAss) if waiting for PKT_CTRL_ACK answering UL_ACK_NACK (FinACK=1) ......................................................................

Delay ImmAss(PCH, PktDlAss) if waiting for PKT_CTRL_ACK answering UL_ACK_NACK (FinACK=1)

In that state (ul_tbf=TBF_ST_FINISHED), we are unable to reach the MS to assign a new DL TBF. * MS Is not available in CCCH because it's attached the PDCH. * MS won't be able to PKT_CTRL_ACK a PktDlAss on PACCH, because next thing it will do is to PKT_CTRL_ACK the UL_ACK_NACK(FINACK=1) we already polled it for, and immediatelly after that it will release the UL TBF on its side and go back to packet idle mode.

Hence, we must wait for MS to send the PKT_CTRL_ACK to us in order to be able to assign the DL TBF in PCH (CCCH).
