Andre Puschmann c0be8187c8 rlc interface: convert entire read_pdu() interface to return uint32_t 
we had it returning int but had a bug in using the return value properly,
i.e. handling when -1 was returned in RLC TM.

Thinking about it more, it doesn't make sense to have a negative return
value here anyway. Either the RLC can return a PDU or not. If it can't the
returned lenght is zero.

general-purpose method for lower layers to signal protocol
failures to higher layers, i.e. RRC.

a reestablishment (UE).

Francisco 59513c0eed fix bearer reactivation in case the RRC session is recovered after max KO 4 years ago
Andre Puschmann fbb151af2d enb,rrc: fix bearer re-activation after max KO 
this patch makes sure that if RBs have been deactivated after
max KO on either the DL or the UL, they are reactivated if either
of them is working again.

UL/DL are always activated together, even if just one of them
recovers. The KO counter (or timer), however, is not stopped implicitly.

Francisco f2a56c9139 simplification of multiqueue design. 
- the consumer does multi-staged waiting:
  1. spins first across all queues in a RR fashion
  2. each queue access is done with a try_lock.
  3. if the try_lock fails, it increases the number of spins needed
  2. if no queue had data, the consumer sleeps for 100 usec.
- no differentiation between queues, in terms of notification features

Andre Puschmann b2825d1280 mac_controller: after maxRetx disable ALL UE bearers 
the reasoning here is that the only way to recover
from the maxRetx event is the UE attempting a reestablishment.

No further traffic, neither control nor data is scheduled
until then.

Andre Puschmann b61be7878a enb,rrc: split RLF counter and timer handling for DL/UL/RLC 
this patch splits the counter and timer handling for PHY DL, PHY UL,
and RLC errors and makes sure that, for example, a successful DL
does not cancel the UL RLF timer, and vice versa.

They all use the same timeout value which is user-configurable.

Francisco ef9d1b8c13 stack optimization - reduction of contention in multiqueue class 
With the new design, each queue created in the multiqueue object has its own mutex.
Pushing tasks to separate queues will, therefore, not cause contention.
There will be, however, still contention between the popping thread and the pushing threads.

herlesupreeth 0f06ec0d9c Add feature to provide custom GTP-U (S1) address to be advertised inside S1AP messages 
This feature is useful in scenarios where eNB is behind a NAT and EPC on public cloud
Since eNB's GTP-U can only bind to IP address visible in it's host (usually a private IP beind a NAT), it advertises the same to UE in S1AP message
resulting in traffic from EPC to eNB (DL traffic) not able to reach eNB. This commit solves this issue by providing a means to advertise a different IP address than the one GTP-U UDP socket is bound to.
This IP is usually advertised in InitialContextSetupResponse and E-RABSetupResponse.

In order to make use of this feature, use the following parameter in enb.conf

Example:

gtp_advertise_addr = 213.61.141.82
