Dave,

Please hold off this 5 patch series. I have two critical bug fixes that take priority and will probably clash the pci probe re-factoring patch.

Thanks,

Subject: [PATCH NEXT 1/5] netxen: fix physical port mapping

The PCI function to physical port mapping is valid only for
old firmware. New firmware (4.0.0+) abstracts this.
So driver should never try to access phy using invalid
mapping.
