Dhananjay Phadke 443be7960b netxen: improve msi support 
Recent netxen firmware has new scheme of generating MSI interrupts, it
raises interrupt and blocks itself, waiting for driver to unmask. This
reduces chance of spurious interrupts.

The driver will be able to deal with older firmware as well.
