Well, the command fails because of this check (mbm is 20 in his case)
cfg.c:

return -EOPNOTSUPP;
That mbm % 100 looks quite strange to me..any idea what that is supposed to
accomplish?
There's a later division by 100 to go from mBm to dBm ... I think you
want 2000, not 20.
Well, it's documented in iw to be 'mBm', though I surely wouldn't have known
what that stood for (nothing useful shows up on google for 'mBm units').
Thanks,
