For performance monitoring, trace time intervals when Tx vring
is idle/not idle. Use CPU cycle counter for this, because jiffies is
too rough, and other precise time measurement methods involve
overhead while get_cycles() should be fast.
This used to provide some estimation for percentage when Tx vring
was idle, i.e. when hardware is under-utilized.
Estimation is not precise because of many reasons - CPU frequency scaling,
grt_cycles() may be per core etc. But still, it is good estimation

Provide 2 files on the debugfs:
- "rxon": write channel (1..4) to open Rx on it, 0 to rxoff
- "tx_mgmt": write binary frame, starting from MAC header

one need to care about turning receiver on/off before/after tx_mgmt

Correct sequence is:
 echo $channel > rxon
 cat mfmt_frame > tx_mgmt
 echo 0 > rxon
