I am surprised given what you've said in the past :-)

| I took it as a hint that, given that we have already have six
| interfaces that affect WLAN power in one way or another and still
| can't give a simple answer to what seems to be a simple question,
| "do it just because we can" doesn't seem to be an efficient policy
| when it comes to actually providing a solution in this case.
|
| For those who haven't kept count, here are the options:
|
| 1) SIOCSIWTXPOW
| 2) AR6000_IOCTL_EXTENDED/AR6000_XIOCTRL_WMI_SET_WLAN_STATE
| 3) sysfs power_on
| 4) global suspend/resume
| 5) module load/unload
| 6) bind/unbind
| 7) rfkill

With rfkill we can retire the sysfs one entirely (since we found out in
the meanwhile it doesn't do anything useful), the IOCTL one and the
wmiblah applet aren't needed by mortal users then either.

suspend / module / bind-unbind can be said of almost anything anyway.

So... rfkill will bring healing and sanity to WLAN power interface...
let's do it :-)
