Thanks for the patch! But I already delete the whole fakehard driver.
The patch to remove this driver is already in net-next.

There was too many issues with the fake hardMAC drivers and we don't
really supported a "real" hardMAC transceiver. For my rework to grab the
good things from wireless implementation and put 802.15.4 functionality
on it I simple delete the whole driver and _maybe_ add a new one with
the new introduced interfaces for possible hardMAC functionality.

This patch could go into bluetooth(net)/stable but I don't think that
there are many users for this driver.
