Francisco Paisana eafc003671 Altered the way the generation of the scheduling decision for a given 
TTI is made. Instead of generating one CC in each dl_sched()/ul_sched()
call, all CC decisions are generated at once. This avoids race
conditions with calls from the RRC to the MAC to configure UEs.

Francisco Paisana c46402c836 fix phy configuration during handover on srsenb. The function srsenb::rrc::ue::fill_scell_to_addmod_list assumes that the phy_cfg of the PCell is up-to-date, which was not the case.

Andre Puschmann 655c7ae8ae enb: fix warning when removing user 
when removing a user from the eNB we iterated over all possible LCIDs
and set the buffer state to zero in the scheduler.

this resulted in following log entries:

13:57:23.856334 [RRC ] [I] Received Release Complete rnti=0x46
13:57:23.856352 [MAC ] [W] [ 5149] The provided lcid=6 is not valid
13:57:23.856362 [MAC ] [W] [ 5149] The provided lcid=7 is not valid

13:57:23.856376 [MAC ] [W] [ 5149] The provided lcid=10 is not valid

we now check if the bearer exits at RLC and only report those to the MAC.

Matt Johnson e9eab89a6b srsenb/rrc: Avoid crash when CSFB requested but sib7 not configured 
This commit addresses an issue where if a UE requests a release for
circuit switched fallback, but the sib7 carrier freqs info list is not
configured, the eNodeB would crash with a segfault due to attempting
to access an element from an empty list. This commit adds explicit
checking to handle the empty list case. If the list is empty, no
redirect carrier info is added to the connection release message and
the UE must scan for the fallback network itself.

Francisco Paisana 0036941af4 added extra state to S1 target enb mobility FSM. Accounts for out-of-order arrival of MMEStatusTransfer. Also, now we avoid creating DRBs before the MMEStatusTransfer 4 years ago
Andre Puschmann 5e40bfe72c mac_pdu: unpack and print BSR index as well as BSR value in bytes 
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.

Andre Puschmann a7911f0dab pdcp,rlc: refactor SDU queueing policy 
this patch refactors the SDU queuing and dropping policy of the RLC and PDCP layer.
the previous design had issues when packets have been generated at a higher
rate above the PDCP than they could be consumed below the RLC.

When the RLC SDU queues were full, we allowed two policies, one to block on the write
and the other to drop the SDU. Both options are not ideal because they either
lead to a blocking stack thread or to lost PDCP PDUs.

To avoid this, this patch makes the following changes:

* PDCP monitors RLC's SDU queue and drops packets on its north-bound SAP if queues are full
  * a new method sdu_queue_is_full() has been added to the RLC interface for PDCP
* remove blocking write from pdcp and rlc write_sdu() interface
  * all writes into queues need to be non-blocking
  * if Tx queues are overflowing, SDUs are dropped above PDCP, not RLC
* log warning if RLC still needs to drop SDUs
  * this case should be avoided with the monitoring mechanism

using ZMQ) the zmq-based radio to timeout. as a result

stack thread is too slow in processing its tasks.

For RF hardware the default is still 8192 TTIs, for ZMQ 1 TTI is used.

macros are used but we would need to change the variable name
to replace them
