Subject: [PATCH 15/17] batman-adv: Use proper name for gateway list head

From: Simon Wunderlich <[email-masked]>
Date: Thu, 27 Oct 2016 21:01:48 +0200

From: Sven Eckelmann <[email-masked]>

The batman-adv codebase is using "list" for the list node (prev/next) and
<list content descriptor>+"_list" for the head of a list. Not using this
naming scheme can up in confusions when reading the code.
