There are plans to port if_iwx, yes. I have ordered an adapter to work on, unless others beat me to it, in the (nearby) future. Might arrive somewhere in the next two months.

In the meanwhile, can you elaborate on 1) which laptop (or desktop) ships with AX200, and 2) provide some PCI ID details?

Are those SKUs? Because HP's website doesn't retrieve those models: https://www8.hp.com/uk/en/search/search.html?nores=true&qt=HP%20EliteBook%20HSN-122C

Still working on the port.
Comment 8 vidwer+fbsdbugs 2020-03-24 11:21:25 UTC
Still working on the driver. Currently, while loading if_iwx it comes 'up' in dmesg with:

iwx0: <iwx22000_cfg, in need of a better name /* Intel(R) Dual Band Wireless AC 9260 */> mem 0xf0000000-0xf0003fff at device 0.0 on pci2

Comment 9 vidwer+fbsdbugs 2020-04-21 11:27:20 UTC
Hi, I could use your help to make sc_debug actually show log output from IWX_DPRINTF().
sc_debug is (locally) set to 1 in iwx_attach(), in the SYSCTL_ADD_INT() macro and through dev.iwx.debug in /boot/loader.conf
Comment 10 delleceste 2020-04-25 10:17:53 UTC
Hello! 
Is there already a way to test the driver?
Will it support only G or also N / AX ?
Thanks.

Please contact the project leadership to move support for this particular hardware forward.

This is taken care of.

Thanks. I'm sorry I did not understand whom I should address to get this information. Is it wireless@freebsd.org?
Thank You
Kind regards

I should probably take this given I am tasked to do 11ac for it which also means adding newer bits to the driver.  Don't hold your breath just yet.  I'll be a few weeks out at least.
