BIG-IP system drops SCTP INIT multi-homing message with checksum 0x00000000.
System drops these SCTP packets.
This occurs when the SCTP packet's verification tag is 0x00000000 and the checksum also is 0x00000000.
None.
Added a db variable to disable verification of SCTP checksum when ingress packet's checksum is zero. The current default behavior is not changed if this db variable is not enabled.
