--- Comment #7 from Mark Johnston <markj at FreeBSD.org> ---
I have access to a laptop with a 9560 chipset.  The big difference in the
9000-series chips is that they support MSIX multiple receive queues and use a
different interface ("RFH", not sure what that stands for) to configure them.

I converted iwm to use this interface, based on iwlwifi and lwhsu and wjguo's
work, and am trying to configure a single RX queue with MSI.  I'm able to load
the firmware image, and get an "firmware alive" interrupt after, but I don't
get any RX interrupts, so we time out waiting for a reply to the "alive"
message.
