Sepherosa Ziehau is planning to remove support for the awi(4), ray(4) and gx(4) devices in the next DragonFly release. These are (I think) all wireless devices; please speak up on kernel@ or users@ if you actually need/use them.
A running description of activity related to DragonFly BSD.
gx(4) isn’t a wireless device, but the driver for some older Intel Gigabit Ethernet chips. It was in use before Intel started to contribute its own driver known as em(4), but now it’s just obsolete. It was removed from FreeBSD 3 years ago.
