Harald Welte gerrit-no-reply at lists.osmocom.orgReview at https://gerrit.osmocom.org/2291 xUA: Fix endianness handling of PPID and STREAM_ID In their infinite wisdom, the inventors of SCTP designed an API (the sockets API described in RFC6458), where some members are in host byte order (like the stream identifier), while other members are in network byte order (like the PPID). Let's handle this properly (we assumed both are network byte order), and also use 16-bit htons/ntohs fo the PPID, rather than htonl/ntohl.
