http://perforce.freebsd.org/chv.cgi?CH=124956 Change 124956 by avatar@avatar_t40 on 2007/08/09 14:59:34 Fixing invalid channel display in ifconfig(8) by implementing required ioctl(). Note that other information provided by ifconfig(8) such like "list chan" or "list ap" are still not available at this moment. Before an(4) is connected to wlan(4), users are encouraged to use ancontrol(8) to retrieve aforementioned information.
