a packed array so sizeof work. This broke RFMON mode and passing up 802.11 packets. The Linux emulation code was derived from the open source Linux driver to maintain compatibility. LEAP support is added, hints from Richard Johnson. I've verified this locally with PC350v42510.img firmware. More bug fixing from Marco to fix long passwords. Change DELAYs in flash part of driver to FLASH_DELAY which uses tsleep so it doesn't look like your system died during a flash update. Install header files in /usr/include/dev/an Cleanup some ifmedia bugs add "Home" key mode to ifmedia and ancontrol. This way you can manage 2 keys a little easier. Map the home mode into key 5. Enhance ifconfig to dump the various configured SSIDs. I use a bunch of different ones and roam between them. Use the syntax similar to the WEP keys to deal with setting difference SSIDs. Bump up up the Card capabilities RID since they added 2 bytes to it in the latest firmware. Thankfully we changed it from a terminal failure so the card still worked but the driver whined. Some cleanup patches from Marco Molteni.
