Change subject: iu_client: add ranap_iu_page_cs2/ranap_iu_page_ps2 ...................................................................... Patch Set 13: Code-Review+1 (14 comments) Patchset: PS13: in the end, after CR, i notice that this is the iu_client.c code -- which osmo-msc does not use anymore IIRC, meaning that all of the _cs code here is dead? So it might make sense to drop iu_client and copy what osmo-sgsn needs into osmo-sgsn.git. iu_client was an early attempt by me to abstract some common parts between SGSN and MSC, but ended up making more problems than helping. At some point osmo-msc (years ago) started its own copy of this code, to move independently. we can merge this if you like, of course.
