With again almost 600 patches related to wireless, the new 2.6.31 kernel comes with many wireless changes:

• iwlwifi continues unification between 3945 and AGN hardware
• the often-discussed rfkill rewrite, along with rfkill integration into cfg80211
• rndis_wlan starts using cfg80211 as the first full-MAC driver
• iwlwifi support for 3×3 802.11n hardware
• cfg80211 now handles connecting to an ad-hoc network (including wext support)
• initial support for rt2800usb, but still experimental
• a new wl12xx driver for the TI 1251 B/G chip
• ath5k has enabled AP mode
• the hwsim driver can now separate its virtual radios into groups to allow testing mesh topologies
• there's a new driver for new Intel integrated full-MAC hardware, also using cfg80211
