    igb: fix legacy mode irq issue · 6cb5e577
    Andy Gospodarek authored
    I booted an igb kernel with the option pci=nomsi and instantly noticed
    that interrupts no longer worked on my igb device.  I took a look at the
    interrupt initialization and quickly discovered a comment stating:
    
    "DO NOT USE EIAME or IAME in legacy mode"
    
    It seemed a bit odd that bits to enable IAM were being set in legacy
    interrupt mode, so I dropped out the following parts and interrupts
    began working fine again.
