From 1dd27cde30e85774c77349c804229431616d594a Mon Sep 17 00:00:00 2001 From: Daniel Axtens Date: Fri, 9 Mar 2018 14:06:09 +1100 Subject: net: use skb_is_gso_sctp() instead of open-coding As well as the basic conversion, I noticed that a lot of the SCTP code checks gso_type without first checking skb_is_gso() so I have added that where appropriate. Also, document the helper. Cc: Daniel Borkmann Cc: Marcelo Ricardo Leitner Signed-off-by: Daniel Axtens Signed-off-by: David S.
