New Revision: 222021
URL: http://svn.freebsd.org/changeset/base/222021
Log:
Use the halMcastKeySrchSupport capability bit to selectively enable/disable
the multicast key search support for AR5212, AR5416 and later.
The general HAL routine ath_hal_getcapability() implement checking this
but it's overridden by a check in ar5212_misc:ar5212GetCapability().
This restores the later functionality in case it's found to be broken
in any of the 11n chipsets.
