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.

author tested with local 4 port cell. I am not able to verify locally but
it looks ok, we'll revise later if needed.
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.
when the default RF args are used, NULL is passed as argument
to the RF driver. In this case, we should use the previous
SoapySDRDevice_enumerate() and let Soapy pick the device
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.

this patch adds a check to drop all PDCP control PDUs
in order to prevent handling them as data PDUs.
This could happen when the size exceeded the arbitrary length check.
This should fix#1787
* Fix deadlock caused by update_measurements calling in_sync
* Fix overlapping SRS condition
* Do not use shortened PUSCH in transmissions and retx from RAR
* Revert "Fix deadlock caused by update_measurements calling in_sync"
This reverts commit f58c8c8c766f8f95baa3a3bf8287d8e25b2057ba.
* Take into account CRS from neigbhour cells when measuring interference
* fix std::isnormal compilation
* Fixed compilation of test
* Address comments
* Remove unused overrides
this patch refactors the MAC PDU class, the main changes are:
* add to_string() method to pretty print PDU and subheaders
This allows to have a single log entry per MAC PDU with all its
contents.
It removes the C-style fprint() method
* Simplity payload vs. w_payload_ce
Before we've used payload when reading the PDU and w_payload_ce
as a buffer when writing. In all getters we needed to differentiate
between both. Now payload points to w_payload_ce initially and is
only updated when parsing a new PDU.
* add various helpers, e.g. to get subheader index, update a BSR, ..
* fix PDU test to use new to_string() method
simplify logic to check whether a BSR fits and, if so, which type.
before the check has been done in two places.
we now also accomodate for the CE subheader size.
with the B210 and 2 RF ports, i.e. MIMO mode, we have stopped the
Rx stream after changing the rx_samp_rate but didn't start it again.
Either the issue doesn't exist in SISO mode or we never saw it but for MIMO
it can be reproduced easily with rate changes during streaming, i.e.:
$ ./lib/src/radio/test/benchmark_radio -p 2 -t 10 -x -y -s 23.04e6

it fixes#1623.
this happens more often with MIMO since lates are more likely here.
after a late, the Rx stream must not be stopped on the B2xx either.

before the BSR was extracted but the actual index (between 0 and 63)
was not stored but directly converted into bytes.
for log parsing and debugging it is easier to follow the index
value. this patch therefore adds both values to the log message
and extends the API accordingly.
commit #51c6e8d1 introduced a regression in which the 2nd antenna
port was never considered. All MIMO ZMQ based tests therefore failed.
this fixes#1608
the enable_rx_timestamps() for the radio_ctrl object has only been
introduced in Nov 2019 for UHD 3.15 and therefore needs
to be excluded when compiling for 3.14 and below.
Note: According to the original UHD commit in
67dbaa41f2 (diff-60a9387c0fc8406fd5b39fa995dd8c14)
it looks like the Rx timestamps are disabled by default
for UHD versions before 3.15
This commit fixes#1602
- Import the srslog project into srslte.
- Ported srsue app to use the new logging framework.
- Implemented a wrapper that dispatches log entries to srslog.
- Renamed an existing log test to be more specific to avoid name clashes.
