o Clear device-specific PCI register 0x41 (Retry Timeout) during attach
and on resume (reported to fix issues with ACPI) o Add monitor mode support o Add WPA (802.11i) support (not tested extensively though!) o Add a device specific sysctl to control the tx antenna (default to antenna diversity) o Fix sensitivity setting o Fix setting of the capinfo field when associating o Temporarly disable 802.11a channels scanning that was causing firmware panics with 2915ABG adapters until I find a better fix. This breaks 802.11a support. o Temporarly switch back to software WEP until I implement hardware encryption for AES and TKIP too. Approved by: silby (mentor)
