The vmxnet driver always requests irq with name of 'vmxnet' which
is incorrect. It causes multiple entries in /proc/interrupts and confuses
scripts like irqbalance that try and manage smp affinity on network cards.
The fix is simple, just use the standard convention of putting device
name in the irq name. This applies to all kernel versions.
Also, the 'lp->name' structure element is always constant and no longer
used and could be eliminated.
