laforge has submitted this change. ( https://gerrit.osmocom.org/c/osmo-cbc/+/28700 )
Change subject: Rename CBSP,SABP,SBcAP structs and APIs ......................................................................
Rename CBSP,SABP,SBcAP structs and APIs
Rename osmo_*_cbc -> cbc_*_mgr: Now they only hold TCP/SCTP server related conns, but will also hold TCP/SCTP client conns in the near future.
Rename osmo_cbc_*_client -> cbc_*_link: The term "client" is confusing, since it doesn't exist in CBSP/SBcAP, and will later support connecting to server at TCP/SCTP level. Let's use "link" instead, similar to what's used in osmo-bsc which already supports both TCP client and server modes.
