That looks like a hack to me.

Maybe it should be treated like other CRDA flags?  In fact, you can find
this in dbparse.py in the wireless-regdb sources:

    # hole at bit 9. FIXME: Where is NO-HT40 defined?
    'NO-HT40':          1<<10,

However, there are no other references to NO-HT40 in the wireless-regdb
or CRDA sources.  I assume it's not implemented.
