Subject: [PATCH 15/17] batman-adv: Use proper name for gateway list head
From: Sven Eckelmann <sven@...fation.org>
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.
