Ok.

Just to clarify: I understand and accept that the firmware is
closed-source and there are no specifications for the inner
workings of the device, i.e. how the firmware operates so
that (in theory) you could write your own.

I was asking about a specification for the GPL driver-visible
interface of the device to the computer, i.e. basically the
message interchange business: Which mgmt messages can you send,
what do they do, how do you turn off the radio, etc.
I can't see that this has valuable trade secrets in it,
because the driver is GPL anyway.

Ah, ok, so "high" refers to "high priority", not to "highmem"
(> 4GB RAM) or somesuch.

Thanks!
