[S] Change in libosmo-sccp[master]: ipa: use LSBs of file descriptor as SLS in IPA->M3UA direction

by laforge

laforge has submitted this change. ( https://gerrit.osmocom.org/c/libosmo-sccp/+/34264?usp=email ) Change subject: ipa: use LSBs of file descriptor as SLS in IPA->M3UA direction ...................................................................... ipa: use LSBs of file descriptor as SLS in IPA->M3UA direction when IPA/SCCPlite traffic traverses the osmo_ss7 stack, so far the SLS of the MTP3 label was always set to 0 (default initialization). However, in order to achieve a better distribution of signaling traffic in SS7 networks that actually utilize the SLS to select any links (or ASPs), it makes sense to use non-zero values. Instead of introducing some kind of new, configurable attribute for each ASP (IPA client connection), let's simply use the lower 4 bits of the file descriptor integer. Those file descriptors should have a roughly equal distribution, resulting in traffic (from multiple IPA clients) to be spread across the 4-bit SLS number space. Also, this mechanism ensures that traffic from one IPA client will always get the same SLS and hence routed the same way in any underlying CS7/SS7 network.
