Subject: [PATCH] net: force bridge module(s) to be GPL
Date: Thu, 10 Sep 2009 14:51:46 -0700 [thread overview]
Message-ID: <20090910145146.3ee30338@nehalam> (raw)
The only valid usage for the bridge frame hooks are by a
GPL components (such as the bridge module).
The kernel should not leave a crack in the door for proprietary
networking stacks to slip in.
