IPA: no point code insertion to SCCP
As incoming messages on the IPA/SCCPlite protocol do not have a MTP routing label, nor is there any requirement for the SCCP Addresses to contain point codes, the IPA/SCCPlite support of osmo-stp currently inserts/adds “artificial” point codes at the point of IPA/SCCPlite ingress. Those point codes are added both to the [newly-created] MTP label, but also to the SCCP Addresses.
We require a mode of operation for osmo-stp where the point codes are not inserted into the SCCP addresses.
ipa: VTY config option to explicitly enable/disable SCCP patching
When receiving SCCP messages from an IPA peer/ASP, osmo-stp so far
unconditionally inserted origin/destination point codes int the SCCP
called / calling party addresses.
This behaviro is now made optional with the introduction of the
following per-AS configuration:
"point-code override patch-sccp (disabled|both)"
The default behavior is switched from 'both' to 'disabled' at the same
