sctp ppid value error #24

For sctp s1ap protocol ppid should be 8.While giving sctp_send(msg,ppid=8),Whireshark shows 301989888 and putting ppid = 301989888 , it shows ppid=8.

The Linux SCTP API requires the user to pass the PPID with a network byte order. Just do this:

from socket import htonl sctp_send(msg, htonl(ppid))

Forgot to say, for S1AP, PPID is 18, not 8.
