svn commit: r219318 - head/sys/dev/ath/ath_hal

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.
