2.6.0-test9-mjb3

[Martin J. Bligh]

The patchset contains mainly performance, scalability and NUMA stuff, 
and anything else that stops things from irritating me. It's meant to be 
pretty stable, not so much a testing ground for new stuff.

I'd be very interested in feedback from anyone willing to test on any 
platform, however large or small.

What's protocol 254 and why do you need it?

IBM VPN software needs it for a hacked on version of freeswan. 
Don't blame me for that bright idea ... we have to live with it
somehow ;-)
