Andre Puschmann b994255b35 enb: fix handling of GTPU and S1AP init return values 
if the eNB stack startup fails, for example due to binding
the wrong GTPU socket or similar issues, the eNB should stop
and log a message. Previously the return values for
S1AP and GTPU init were not even evaluated.

Francisco Paisana 1839b9a6e5 cleaned up paging code to avoid extra processing steps in worker threads 5 years ago
Francisco Paisana 9c028ab723 removed user_mutex from srsenb::rrc. All that needed to happen was the prach_worker calling add_user from stack thread (done in an earlier PR), and the get_metrics run in the stack thread. I achieved the latter with an extra metrics queue 5 years ago

Andre Puschmann b7aad27d86 move packing of SCell list into extra method and add fill PHY config on the spot 
previously we've packed the RRCReconfig with SCellToAddMod list and have then
parsed the message again to pack the PHY config dedicated for the new SCell carrier. This
is now done in one step.

Andre Puschmann 2edecea33e fix SIB transmission for CA 
Avoid double buffering of SIBs in MAC as this would require one buffer for each CC.
Instead, use byte_buffer managed by RRC that contains packed SIBs to avoid
double memcpy for each SIB tx. Only use MAC provided buffer in error case.

Also avoid MAC calling RLC for each SIB and call RRC directly.
