From be4947bf46cb0e7a7d089e03c61bab35f1e695ce Mon Sep 17 00:00:00 2001 From: Xin Long Date: Thu, 29 Sep 2016 02:37:28 +0800 Subject: sctp: change to check peer prsctp_capable when using prsctp polices Now before using prsctp polices, sctp uses asoc->prsctp_enable to check if prsctp is enabled. However asoc->prsctp_enable is set only means local host support prsctp, sctp should not abandon packet if peer host doesn't enable prsctp. So this patch is to use asoc->peer.prsctp_capable to check if prsctp is enabled on both side, instead of asoc->prsctp_enable, as asoc's peer.prsctp_capable is set only when local and peer both enable prsctp.
