cxgb3: Chelsio T3 1G/10G ethernet device driver

Jeff,

I resubmit the patch supporting the latest Chelsio T3 adapter. It incorporates Arjan's feedbacks:
- remove unnecessary ifdefs
- updates the pci ressource managment
- add flush after register write.

It is built against Linus'tree.

A corresponding monolithic patch is available at this URL:
http://service.chelsio.com/kernel.org/cxgb3.patch.bz2

This driver is required by the Chelsio T3 RDMA driver which was updated on 12/20/2006.

Cheers,
Divy
