From 3c9187049214127d3401926b033d05eb75d69c39 Mon Sep 17 00:00:00 2001 From: Xin Long Date: Fri, 30 Jun 2017 11:52:16 +0800 Subject: sctp: remove the typedef sctp_paramhdr_t This patch is to remove the typedef sctp_paramhdr_t, and replace with struct sctp_paramhdr in the places where it's using this typedef. It is also to fix some indents and use sizeof(variable) instead of sizeof(type). Signed-off-by: Xin Long Signed-off-by: David S.
