iwlwifi on 13-STABLE working!

Today I tried iwlwifi for the first time on my AX200. It's been almost
flawless to this point and this message is going out over that interface.
Possible issue was that on my second  start of this interface, it failed to
associate. I restarted again and it came up fine. I don't currently have
debug configured, so I don't have any real information on the failure.
Performance is not impressive. Hopefully it will improve. 19M down and 4.5M
up while my phone gets about 300M down and 190M up. Still, it's about the
same as I was getting on my 11b Realtek USB2.

Thanks, Bjorn (and the FreeBSD Foundation) for your work on this! It's
great to finally be able to use this card.
