This bit has been devised to work around a variance in CNXT DSLAM code behaviour. AR7 is tuned and tested with this bit in its default mode (flavour A). When this bit is set to non-default mode (flavour b) it is known to eliminate CRC and improve US rate in G.DMT and T1.413 modes. The non-default mode is a temporary work around which has not been tested beyond verification that it fixes the noted problems. This behaviour is seen with E67.1.11 and D79 code bases when tested in lab conditions. The level of performance of AR7 modem is not guaranteed when this bit is in non-default mode. The use of this API in nondefault mode is not recommended unless the stated issues become a limitation in deployment. TI will not engage in further modem tuning with this bit set in nondefault mode.
