Andre Puschmann ff5f215df9 rf_soapy: print warning when using the Lime with shorter sample rates 
the Lime has better performance when using the default LTE sample
rates due to filterering being done in the LMS RF chip.

Print a warning when using the Lime with the non-default LTE rates.

Andre Puschmann 5f7f818abb pdu: fix bug in BSR table lookup 
the bug causes the BSR to return a bsr_idx of 0, i.e. no data
pending, when the buff_size was reported to be 1 B only.

Instead, the UE should return BSR idx 1, i.e. between 0 < BSR <= 10.

Andre Puschmann 286844b3dd mac_pdu: reset subheader state when deleting from PDU 
when packing MAC PDUs, adding a new SDU might fail, for example
because RLC couldn't provide a new PDU. The muxer then needs
to delete the subheader from the PDU again.

When adding a padding BSR at the end, the same subheader is again
used to store the BSR, so any state in that subheader should be removed.

In the particular case, this was causing an issue when logging a LBSR
because the LCG buffer states are printed using the payload buffer,
which was still pointing to some memory that was used when trying
to add the new RLC PDU in the beginning.

Andre Puschmann 035d989737 pdu: fix unpacking of LCG2 of LBSR MAC CE 
LBSR packing is fine but this makes the eNB do wrong things
because it thinkgs LCG2 has no or too much data to send.

LCG2 is our default LCG for DRB1. One occasion we saw the issue
is doing full rate TCP DL which requires quite a bit of ACK traffic
back to the sender. With the BSR for LCG2 being wrong, providing
UL grants was delayed and so the TCP DL throuhgput was very low.

In the log below we see that the buff_size[2]=1 so there is data to send.
Interestingly, the packing was correct so Wireshark displays it correctly.
But the unpacking not, as can be seen in the MAC log below which reports
0 buffer state for all LCGs

22:08:54.804792 [MAC ] [I] [ 5084] pdu_get: sdu_len=1212, channel.sched_len=1213, bsr.buff_size[2]=1

Andre Puschmann f155b7a5d5 rlc: fix stopping of poll retx timer (#2006) 
* rlc_am: add TC for pollRetx timer handling

* rlc_am: fix stopping of pollRetx timer

stopping the pollRetx timer when receiving a status PDU
without checking the acknowledged PDUs is wrong.

if an ACK for another PDU, for which the polling bit has been set,
is still pending, it won't be rescheduled until another
PDU is transmitted that again starts the pollRetx timer.

this fixes the issue with missing RLC AM segment retx in #1992,
and #2003

Andre Puschmann 7cf919e2af Fix MAC PDU packing after sending Truncated BSR (#2004) 
* mac_test: add extended TBSR unit test

unit test to MAC UL packing after sending a TBSR

this fixes the MAC issues described in issue #2002

* mux: fix updating of LCG buffer state after packing PDU

we've previously lowered the buffer state of the LCG according
to the bytes that have been scheduled, but not according to
those that have been actually included in the PDU.

* proc_bsr: fix LCG buffer state updating for TBSR

when sending a TBSR do not update the internal buffer
state of the BSR proc.

This caused issues because the buffer state for all LCG that
are not included in the TBSR are set to zero, although at least
one LCG does have data to transmit.

* rlc_am: include LCID when logging retx of SN

Andre Puschmann 1b97ba5300 benchmark_radio: fix duration and thread priority 
I noticed that the app didn't configure the process with
RT thread prio. But it then turned out that in order to do
that we need to actually spawn a new thread. Also a few other things
didn't work out of the box.

In summary the changes are:
* fix duration to support more than 120s
* move main functionality in thread
* set high priority for radio thread
* only return success if no radio errors occured

Andre Puschmann f647343f18 rlc_am: fix poll bit during header reconstruction 
this makes sure that the reconstructed RLC AM header
has the poll bit set when any of its segments had it set.

this triggered a bug in RLC AM because the Status PDU
isn't transmitted for a RLC PDU that was segmented and
only the first segment had the P flag set.

gracid f67a152a2a Remove unnecessary Lime calibration step from Soapy implementation 
When using srsLTE with Lime devices, calibration was performed before any configuration steps have happened, thus making calibration values invalid. Removing Lime specific calibration step from rf_soapy_imp makes so that devices will be automatically calibrated by SoapyLMS on rf_soapy_start_stream call.

Tested and working with srsENB using LimeSDR-USB v1.4 and LimeSDR-Mini v1.2 boards.

Jan Remeš 8c7b7cc55a libsrslte_rf: add library version 
This patch adds version string to the 'libsrslte_rf' library.
This results in the library being built as
    libsrslte_rf.so.20.04.2
with the following symbolic links
    libsrslte_rf.so.0 -> libsrslte_rf.so.20.04.2
    libsrslte_rf.so -> libsrslte_rf.so.0

The SRSLTE_SOVERSION variable should be increased with each backwards
incompatible change of the library.
