makes sense.
As a matter of fact i wonder whether it wouldn't be smarter
to allocate the dma-ble memory on the first request and
keep it around until the driver is unloaded.
If i read the code in iwi_load_firmware() correctly,
the contiguous chunks cannot be longer than 8191 bytes,
so a single contiguous buffer is not mandatory.
I just don't know if we can write the firmware to the adapter
with multiple operations (lists of command blocks) or
it needs to be just a single list ?
cheers
