From 3aa623da789ff6edf789b5655debf33f50b3a9b2 Mon Sep 17 00:00:00 2001 From: Xin Long Date: Sat, 25 Nov 2017 21:05:32 +0800 Subject: sctp: use sizeof(__u16) for each stream number length instead of magic number Now in stream reconf part there are still some places using magic number 2 for each stream number length. To make it more readable, this patch is to replace them with sizeof(__u16). Reported-by: Marcelo Ricardo Leitner Signed-off-by: Xin Long Acked-by: Marcelo Ricardo Leitner Signed-off-by: David S.
