There’s a refresh of the iwm(4) driver in DragonFly, which will apparently help most for iwm-9000 and iwm-9260 owners.
I don’t know which product names correspond with those chipsets, but you may be able to tell who you are. Interesting note: original driver via OpenBSD, then synced from FreeBSD version. Cross-pollination!
It is good to see hardware compatibility increasing. Do you know if the problem the Phoronix guy had where DragonflyBSD didn’t not on the third-generation Ryzen Threadripper is a general incompatibility and whether it has been fixed yet?

No idea about it.
