Sukchan Lee 4537142929 [EPC] Support ePDG Interface (#1039) 2021-06-21 22:36:38 +09:00
Sukchan Lee 1bed0d5872 [#568] Add GTP-U Error Indication Handling 
So far, no operation was performed when Error Indication was received
from eNodeB. For that reason, I solved #568 issues by controlling
the MME to prevent this from happening.

Now, when GTP-U Error Indication is received, MME and SGW are implemented
to do what they have to do. I hope that the network can be restored
by responding appropriately even if Error Indication occurs.

Sukchan Lee fb7ae93b07 fix the bug for ping. 
gtpv2c_header_t and gtp_header_t(v1) is merged to gtp_header_t.
In this case, sizeof(gtp_header_t) is 12 because the structure has an
attribute of gtpv2c header something like sequence number.

As such, we should not use sizeof(gtp_header_t) directly.
Use GTPV1U_HEADER_LEN and GTPV2C_HEADER_LEN.
