Author: adrian Date: Sun Mar 6 00:30:43 2011 New Revision: 219318 URL: http://svn.freebsd.org/changeset/base/219318 Log: Add an EEPROM op that extracts out the power table offset. It defaults to -5 dBm for eeproms earlier than v21. This apparently only applies to Merlin (AR9280) or later, earlier 11n chipsets have a power table offset of 0. All the code in ath9k which checks the power table offset and takes it into account first ensures the chip is Merlin or later.
