909 * sequence. Hence a macro 'SWITCH_SIGN' has been defined
910 * which will be defined in the array of configuration values
911 * (xena_dtx_cfg & xena_mdio_cfg) at appropriate places
912 * to switch writing from one regsiter to another. We continue
913 * writing these values until we encounter the 'END_SIGN' macro.
914 * For example, After making a series of 21 writes into
915 * dtx_control register the 'SWITCH_SIGN' appears and hence we
916 * start writing into mdio_control until we encounter END_SIGN.
