commit f8d59f7826aa73c5e7682fbed6db38020635d466
Author: Bruce Allan <bruce.w.allan@intel.com>
Date:   Fri Aug 8 18:36:11 2008 -0700

    e1000e: test for unusable MSI support
    
    Some systems do not like 82571/2 use of 16-bit MSI messages and some
    other systems claim to support MSI, but neither really works.  Setup a
    test MSI handler to detect whether or not MSI is working properly, and
    if not, fallback to legacy INTx interrupts.
