Can't happen with if_ix, see below. Is what can happen is that
the irq is being stomped on by someone else though. Or the board
is not soft set for the correct connector.

The if_ix.c driver can fully read the softset IRQ value and reports
any descrepancy between it and what the kernel config value is:
/*
* Get the encoded interrupt number from the EEPROM, check it
* against the passed in IRQ. Issue a warning if they do not
* match. Always use the passed in IRQ, not the one in the EEPROM.
*/
irq = ixeeprom_read(unit, eeprom_config1);
irq = (irq & IRQ) >> IRQ_SHIFT;
sc->irq_encoded = irq;
irq = irq_translate[irq];
if (irq != dvp->id_irq) {
printf("Warning board is configured for IRQ %d\n", irq);
}

I am not any questions, infact the only list (that has any activity) that
I am on is the commit list.
