ue,sync: increase timeout for entering IDLE to 2s (#1941) 
in ZMQ runs we've seen that entering idle could take quite
a bit of time depending how quickly workers get their samples
sent or reconfigurations done.

In one example up to ~160ms

this patch increases the maximum wait time to 2s.

Andre Puschmann 287c653755 proc_bsr: improve BSR logging to print name of triggered BSR instead of enum 2020-10-16 09:16:54 +02:00
Andre Puschmann 3994407f46 proc_bsr: fix BSR insertion in UL PDUs 
the BSR trigger wasn't reset after includinga regular or periodic
BSR inside a PDU. This caused the muxing to include another BSR in the
next UL grant. For very small grants, for example with 6 PRBs, this
causes the UE to send way too many BSRs.

Andre Puschmann 7352bfa4bd mac_test: add unit test for retxBSR timer 
this test varifies the correct operation of the retxBSR timer.
the first PDU includes a long BSR to indicate more LCGs have
data to transmit. The retxBSR timer is started and subsequent
PDUs should not send a regular BSR.

After the retxBSR timer expires, a UL PDU should again include
a BSR.

Andre Puschmann fab86382c1 mac,rrc: add interface to set SR config explicitly without touching any other MAC function 
when releasing PUCCH/SRS (see 5.3.13 in 36.331) we need to reset the SR config as well.
In our case, SR is handled by MAC so we need to (re-)configure MAC, not all of
MAC though, just SR.

Andre Puschmann e72219789e ul_harq: don't clear payload buffer during HARQ reset 
this fixes #1791 which was caused by a race between
the PHY workers preparing a new UL-SCH PDU and the Stack resetting
the MAC, which in turn resets the HARQ processeses, which cleared
the buffer and set the length to zero.

Not explicitly clearing the buffer on a HARQ reset seems to be
fine since the PHY worker clears the buffer before starting to
pack a new PDU anyway.
