From: Xin Long Date: Sat, 5 Aug 2017 11:59:57 +0000 (+0800) Subject: sctp: remove the typedef sctp_xmit_t X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=86b36f2a9b9ea58dd2100b0e6f1f45a1f67ee95e;p=openwrt%2Fstaging%2Fblogic.git sctp: remove the typedef sctp_xmit_t This patch is to remove the typedef sctp_xmit_t, and replace with enum sctp_xmit in the places where it's using this typedef.
