the Michael MIC is stripped off this frame,
verification has been done by the hardware.

The IV/ICV are stripped from this frame.
If this flag is set, the stack cannot do any replay detection
hence the driver or hardware will have to do that.

Set this flag if the FCS check failed on
the frame.

Set this flag if the PCLP check failed on
the frame.

The timestamp passed in the RX status (<em class="parameter"><code>mactime</code></em> field)
is valid. This is useful in monitor mode and necessary for beacon frames
to enable IBSS merging.
