Subject: [PATCH net-next 05/11] 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 <lucien.xin@...il.com>
