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

Hi,

I resubmit the patch supporting the latest Chelsio T3 adapter. It incorporates feedbacks from Stephen:
- per port data accessed through netdev_priv()
- remove locking in netpoll() method

It also adapts to the new workqueue rules.

This patch adds support for the latest Chelsio adapter, T3. It is built against 2.6.19.

A corresponding monolithic patch against 2.6.19 is posted at the following URL: http://service.chelsio.com/kernel.org/cxgb3.patch.bz2

We wish this patch to be considered for inclusion in 2.6.20. This driver is required by the Chelsio T3 RDMA driver which was updated on 12/02/2006.

Cheers,
Divy

Minor style stuff (that can be fixed later).
1) /* C style comments */ are preferred over // C++ style
2) Please use C99 style structure initializers especially for OS interface structures like ops for MII.
