Hi All,

I have started working on the iwi (3945abg) driver. From the linux
refrence driver, I have derived the format of the ucode and how to
load the ucode onto the card. However, I am not sure how to load the
raw ucode, before I can parse the ucode and load it onto the firmware.
Do I have to read the ucode file myself or is there any other
mechanism.
Add a new ioctl command into driver's ioctl handler, then add a user
space program to parse the raw ucode, and send the parsed results to
driver through the newly added ioctl command.  Driver can then load
the results (e.g. text and data segments) into device.  Take a look at
iwi(4) and iwicontrol(8) for example.
Best Regards,
sephe
