Yes, this empirical behavior does not seem to match one's intuition on what
the flag should do.
The flag means the hardware does the rc4 but doesn't bother to deal with the
IV/ICV. If you're going do software encryption, there's no reason to bother
with that flag, as that says your hardware supports and does rc4 in hardware.
That is fair enough, but why does that flag ever make any difference when the user has not provided
a set_key callback. My interpretation of the code was that this was one means of indicating that we
were never going to do any hardware encryption
It would be very helpful to driver writers if the comments in include/net/mac80211.h we improved.
This flag has none, but I don't think it is that obvious.
