For 6x00 2x2 NIC, two types of Power Amplifier are available. In order for uCode to apply correct tx power, driver needs to program the CSR_GP_DRIVER_REG register and let uCode know the type of PA. If driver do not program CSR_GP_DRIVER_REG register (default to 0), then it is uCode's decision for tx power 2x2 Hybrid card: use both internal and external PA 2x2 IPA(Internal Power Amplifier) card: internal PA only Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.
