Matthew Dillon and Adrian Chadd have updated the wifi setup in DragonFly, incorporating Adrian’s FreeBSD changes (and merging back some of Matt’s from DragonFly). This affects the ath, rum, iwm, iwn, run, bwn, urtwn, wi, ral, iwi, ndis, and wpi drivers. The ‘an’ driver has been removed, too. I’m not going to even try to link to all the commits.
If you’re on DragonFly master and are using one of these devices, now is the time to update and try. Note that this removes the separate network interface that’s specific to the device and creates only a wlanX device.
Update: Matt reminded me that at least half the work came from Imre Vadasz; I missed it because I was only looking at the commit email names – mea culpa.
