BSSMAP: Introduce Osmocom Osmux Support and CID extension IE
References: https://git.osmocom.org/libosmocore/commit/?id=18506c850c3bbcbfa814e07dc02a17fdb5f7bb9a https://osmocom.org/issues/2551 IE GSM0808_IE_OSMO_OSMUX_SUPPORT (T, 1 byte) is sent in AoIP appended to BSSMAP RESET in order to announce the peer that its MGW supports handling Osmux streams upon call set up. IE GSM0808_IE_OSMO_OSMUX_CID (TV, T 1 byte & V 1 byte) is sent in AoIP during call set up: * MSC->BSC Assignment Request * BSC->MSC Assignemnt Complete The 1 byte value contains the local Osmux CID, aka the recvCID aka CID where the peer sending the Assign Req/Compl will look for Osmux frames on that call. Hence, the peer receiving this CID value must use it to send Osmux frames for that call. As a result, a given call leg BSC<->MSC can have one different Osmux CID per direction. For example: * MS => MGW_BSC ==CID 0==> MGW_MSC * MS <= MGW_BSC <=CID 1=== MGW_MSC This allows for setups with 256 call legs per BSC on scenarios where NAT is not a problem, where MSC can have a pool of 256 CID per MGW_BSC (or remote peer).
