CSCuq63677 - Assertion failure at Function:

sessmgr_sesstrc_allocate_clp_data()

Feature Changes

Improper Removal for Session Tracer

Previous Behavior: SAEGW removal for session trace was not handled properly. Random session trace was selecting
collapsed calls (S-GW/P-GW or SAEGW) which lead to a failure.

New Behavior: Removed all types of session trace (management, random, signaling) from the code for S-GW of
SAEGW. Now, SAEGW collapsed/collocated calls will only get traced at the P-GW for all types of session trace.

CSCuq89887 - pgw sends ICMP MTU too big when user pkt size is greater than

Feature Changes

New Behavior: Removed the 1,500 Bytes restriction for MTU size for P-GW, S-GW, SAEGW and GGSN services.
