Initial set of patches to get it to compile on >= 3.0. Most of the
changes relative to the 2.2 compatable version are include file
related, the new multicast interface (!) and the new PCI interface.
This should work "as-is" but has not been tested (I have not been able
to get a dc21x4x based card for testing).
