New Revision: 217882
URL: http://svn.freebsd.org/changeset/base/217882
Log:
Add ar5416RestoreChainMask() which will undo any AR5416 specific chainmask
overriding after calibration.
This will get set for other two chain radios, such as AR9280 and later on,
AR9287. It should however be a nul operation.
