There are 'longterm' branches for Linux 2.6.27 and 2.6.32, but they
don't include new drivers.  If you want your driver to go into existing
distributions then you have to talk to the distributors.  They will
generally tell you that your driver should be accepted in mainline Linux
first.  So you should first submit a driver based on David Miller's
net-2.6 tree (targetting 3.0) or net-next-2.6 (targetting 3.1).
