Harald Welte 2e426948fe [ENB] Add CFSB support 
This commit introduces CSFB (circuit switched fall-back) capabilities to
srsLTE.  Actually, all the eNB has to do is to send a
RrcConnectionRelease with the RedirectedCarrierInfo IE.

The MME triggers this by the S1AP CS Fallback Indicator IE, which may
be present either in the Initial Context Setup Requst or in the
UE Context Modification Request.

As srsLTE has no support for the UE Context Modification Request at all
yet (!), basic support for this message is introduced in this patch.

Both Mobile Originated and Mobile Terminated CSFB with a coupel of
different UE models have been verified using this patch in a setup
consisting of srsENB attached to an undisclosed EPC connected via SGsAP
to a complete  Osmocom 2G network.

Closes: #358
Closes: #363

Francisco Paisana 67d6a25194 Moving mac timers to stack timers (#638) 
* first step towards moving MAC timers to stack. Mac is still using its own timers. srslte::timers class can be restructured.

* moved timers out of the UE MAC

Pedro Alvarez 09144a2c5f Added check of IP version to the eNB GTP-u. Helpfull for debug. 2019-06-27 17:09:52 +02:00
Andre Puschmann 58763fb714 stack: move initialization of log object into ctor 
this fixes the issue when the stack is torn down if, for example,
the radio couldn't be loaded correctly. it will hence call stop() on all stack
components which are not initialzized yet, and logging therefore doesn't work.
the log object is know during contruction time and therefore can be passed
in as soon as possible.
