Message-ID: <1322267702.2839.383.camel@deadeye>
Date: Sat, 26 Nov 2011 00:35:02 +0000
From: Ben Hutchings <ben@...adent.org.uk>
To: David Miller <davem@...emloft.net>
Cc: Lennert Buytenhek <buytenh@...tstofly.org>, netdev@...r.kernel.org
Subject: [PATCH net-next 3/8] dsa: Combine core and tagging code
These files have circular dependencies, so if we make DSA modular then
they must be built into the same module. Therefore, link them
together and merge their respective module init and exit functions.
