From 659e0bcaebc4ca36e64eac6e9f39c1904b17472c Mon Sep 17 00:00:00 2001 From: Marcelo Ricardo Leitner Date: Sat, 19 Mar 2016 12:17:43 -0300 Subject: sctp: keep fragmentation point aligned to word size If the user supply a different fragmentation point or if there is a network header that cause it to not be aligned, force it to be aligned. Fragmentation point at a value that is not aligned is not optimal. It causes extra padding to be used and has just no pros. v2: - Make use of the new WORD_TRUNC macro Signed-off-by: Marcelo Ricardo Leitner Signed-off-by: David S.
