Subject: [B.A.T.M.A.N.] [PATCH 27/38] batctl: Move translocal debug table to own file
Date: Mon, 22 Oct 2018 00:55:13 +0200	[thread overview]
Message-ID: <20181021225524.8155-28-sven@narfation.org> (raw)
In-Reply-To: <20181021225524.8155-1-sven@narfation.org>

The netlink.c file contains to many different functions and mixes helper
functions with actual command implementations. The debug table commands
should be placed in separate files to better group the command specific
code sections together.
