...
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.

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.

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
