The work to open WLAN-chipsets - OpenBSD's ath
  • Supports some 802.11a/b/g chipsets by Atheros ("ar5xxx")
  • Started as the "ar5k"-project for Linux in 2002
  • Implemented a free driver for the AR5000, the first 802.11a chipset
  • Atheros wasn't really happy about it,
    • hired a developer who wrote the ath-driver with a binary-only HAL
    • which has been imported by FreeBSD and NetBSD
    • ported to Linux calling it the "madwifi"-driver
    • and never ever got imported into OpenBSD
  • The free alternative has been based on the efforts of ar5k
  • It has been re-written as an "Open HAL" for OpenBSD using ath
