[sr-dev] git:sr_3.0: sctp rpc: core.sctp_options debugging version

Module: sip-router Branch: sr_3.0 Commit: 44226358e60f5b69a4c383c892003ad2226c9089 URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=4422635… Author: Andrei Pelinescu-Onciul <andrei(a)iptel.org> Committer: Andrei Pelinescu-Onciul <andrei(a)iptel.org> Date: Thu Nov 12 16:29:40 2009 +0100 sctp rpc: core.sctp_options debugging version core.sctp_options can now have 1 optional parameter. If the parameter is missing it works as before: displays ser's idea of all the sctp config options. If the parameter is present it should have one of the following values: "default" (default send socket), "first" (first sctp socket) or addr[:port]. In this case the kernel sctp options for that particular socket will be displayed, with 0 used for the options that are userspace only.
