New Revision: 227380
URL: http://svn.freebsd.org/changeset/base/227380
Log:
Disable OFDM weak signal detection by default. Leave this to be
enabled if required by STA operation.
This quietens a lot of OFDM errors seen in hostap mode, where
there are no beacon RSSI levels to tune the dynamic range of the
baseband.
This may reduce reception range at the fringes, but does increase
stability.
