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.

RRC-PHY interface (#639) 
RRC-PHY interface refactor. Moved RRC-MAC interface to rrc_asn1_utils and created RRC-PHY interface also in rrc_asn1_utils. All ASN1 includes should be made from rrc_asn1_utils only keeping ue_interfaces clean of ASN1

Tested with different common and dedicated configurations (64QAM UL, 256QAM, CA, SRS enabled/disabled, etc)

Harald Welte 756374419f SRSENB: Add SIB7 (GERAN neighbor) support 
This adds the required missing bits to the eNB config file parser
to enable minimalistic support of parsing SIB7 configuration.

SIB7 contains GERAN (GSM) neighbor cell information, which is important
if you are operating a combined 2G+4G netowrk and want to assist the UEs
to reselect GSM cells once they move out of LTE coverage.

An example SIB7 section looks as follows:

sib7 = {
    t_resel_geran = 1;
    carrier_freqs_info_list =
    (
        {
            cell_resel_prio = 0;
            ncc_permitted = 255;
            q_rx_lev_min = 0;
            thresh_x_high = 7;
            thresh_x_low = 7;

            start_arfcn = 871;
            band_ind = "dcs1800";
            explicit_list_of_arfcns = ( 873, 875, 877 );
        }

    );
};

Harald Welte 44977bcdec [ENB] enb.conf.example: Mention WRITE_SIB_PCAP 
The documentation talks about a MAC protocol trace, but in fact
it is only a protocol trace of dedicated channels.  There's a related
define in the source code, but that's not documented.

Let's at least make the user aware that the MAC pcap trace is
for dedicated channels only, unless he uses that #define.

Harald Welte d01dd7fb91 [ENB] Fix builds with #define WRITE_SIB_PCAP

Harald Welte 844994f2cd [ENB] Fix enabling of MAC pcap file 
when using

[pcap]
enable = true
filename = /tmp/enb.pcap

in enb.conf, there is no pcap file created.

The problem is somewhere in the way how arguments are handled.
pcap.enable is properly parsed into args.pcap.  However, later on,
lte_stack->init(args.stack, rrc_cfg, lte_phy.get()) only passes
args.stack down the road, not args.pcap.  enb_stack_lte::init() then
basically uses args.stack.pcap and not args.pcap, and the latter appears
always false.

Let's remove pcap_args_t from all_args and only use the instance in
stack_args_t.

Dottore Spina 635752c42e Fix call to CHECK_LIBRARY_EXISTS in FindbladeRF 
An invalid call to the CMake macro CHECK_LIBRARY_EXISTS() in
cmake/modules/FindbladeRF.cmake prevents srsLTE to enable
support for the bladeRF driver when:
 * libbladeRF is installed to the same custom prefix we use to build
srsLTE, as with cmake -DCMAKE_INSTALL_PREFIX=/path/to/custom/prefix
 * libbladeRF is installed to /usr/local/lib BUT the linker does not
search this path by default

This trivial patch makes FindbladeRF.cmake provide the linker with the path
libbladeRF is actually installed to.
