Francisco Paisana 42cdc5e340 Allocate all the leftover bytes of the TBS to last allocated MAC SDU. 
Fix the way the RLC header is accounted for depending on the bearer id.
For instance, the SRB0 does not require any RLC header.

Francisco Paisana 55d62a2baa fix rlc buffer updating inside the scheduler to account for RLC headers 2020-10-30 13:35:15 +00:00
Francisco Paisana 44a9ad76f1 avoid sched_ue dangling pointer 
With the sched feature that allows scheduling in TTIs
ahead of time, there is no guarantee that when
the tti arrives to generate a sched result, the stored
raw sched_ue pointers are still valid. For this reason,
I now store the rnti and check if the rnti still exists.

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.

Andre Puschmann a0e4b18507 enb_mac: pre-allocate UE object for quicker PRACH/RAR handling 
we've seen long delays in handling PRACH on low-power devices
such as the RPi4. This was mainly caused by long delays
in creating the UE object on the fly during PRACH handling.

This patch pre-allocates one UE object that is then used
during the PRACH.
