Re: how to have rfkill supported by hal?

[yelo_3 <yelo_3 yahoo it>]

I had a look a your scripts Dan, I see that the "set"  functions are not implemented. I will try to implement them since it is not difficoult, when I have time. Then we might try to propose a patch to hal!
What do you think?

If only it was that easy ;)

You need to disable your script for Dell laptops, in the fdi, otherwise
you end up with 2 levels of rfkill, one at the card level, one at .

The shell script should be in C, and probably use the UDI passed to it,
instead of looking for the device by hand.

Finally, You don't handle values 2 and 3 in the Get. From the ipw2200
README:
 rf_kill
    read - 
    0 = RF kill not enabled (radio on)
    1 = SW based RF kill active (radio off)
    2 = HW based RF kill active (radio off)
    3 = Both HW and SW RF kill active (radio off)
    write -
    0 = If SW based RF kill active, turn the radio back on
    1 = If radio is on, activate SW based RF kill

    NOTE: If you enable the SW based RF kill and then toggle the HW
      based RF kill from ON -> OFF -> ON, the radio will NOT come back on

You can also support the ipw3945 driver with the same settings. I
believe that the iwlwifi drivers are also supportable with the same
script.
