Sadly, this won't help. RGE_RX_INT is already a composite of
RX_OK_INT | RX_ERR_INT | NO_RXDESC_INT

Tried this, but to no avail. It still goes into the sad place. Sadly,
this stupid box doesn't even have a serial port with which I could
provide you access. And I'm out of PCI-e slots to shove in an Intel NIC,
so the on-board Realtek POS is my last option. Well that, or using Linux
with Illumos as a KVM on top of it, but even saying that out loud leaves
a bad taste in my mouth...

Cheers,
