Subject: [PATCH] sctp: keep fragmentation point aligned to word size
Date: Fri, 18 Mar 2016 18:39:17 -0300 [thread overview]
Message-ID: <1458337159-22792-2-git-send-email-marcelo.leitner@gmail.com> (raw)
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.
