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

Andre Puschmann 4fd5395903 change default EARFCN to 3350 or 2.68GHz 
as 3400 or 2.685 GHz is on the edge of band 7, some phones won't connect
to a 20 MHz cell on this EARFCN.

In order to simplify testing with other bandwidths we change the default EARFCN.

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.
