Andre Puschmann e8d6236975 remove init for all RLC TM/UM/AM 
- all RLC entities are now initialized during contruction
- there is no need to check for, e.g., existance of timers, during
  runtime
- there is also no need to call re-init during resume
- timers are freed in dtor

Andre Puschmann 3f613d7183 nas/gw/rrc: make LCID for DRB dynamic 
- add interface to RRC to allow NAS to query the DRB for a given
  EPS bearer id
- extend interface for NAS to setup GW to also pass LCID of bearer
- in NAS, use this new interface to pass actual LCID of the default
  DRB when creating the TUN device

make EIA and EEA algorithms configurable (#323) 
this patch allows to configure the EIA and EEA algorithms
the UE uses and announces during attach. They can
be specified as a comma-separated list.

The patch also removes a dedicated NAS config class and uses
the default nas_args_t type for this. There was a full
duplication of members before.

The patch also converts nas_args_t and usim_args_t into a class
with a default constructor that initialize all booleans.

Andre Puschmann 86e02921f0 fix regression in RLC base introduced during refactor causing eMBMS to fail 2018-09-25 14:04:06 +02:00
Andre Puschmann 22b4396c39 increase default tx_queue length for RLC UM and AM 
- With the current default tx queue length (16 SDUs) the BSR reported by the UE
  is too low if the size of the SDU is relativly small (e.g. 100 B).
  This effectivly causes the eNB to only allocate a small grant
  to the UE and thus reduces the UL throughput for small SDUs.

* Fix ARM NEON code compilation

Fix LV_HAVE_NEON defintion incorrecly used instead of HAVE_NEON in some places
Replace vqabsq_s32 with vabsq_f32 as vqabsq_s32 requires int type (fails to compile)

* Fix timestamp overflow issue on 32-bit systems with Soapy driver

'time_t secs' can be 32-bit on some systems. This causes calculation:
'secs * 1000000000;' to overflow.

  block because no new data nor control PDUs could be created to flush
  the buffers, effectivly causing a system stall.
- Happens in RLC AM stress test regularly with higher drop rates.
