/*********************************************************************************************
* Tnetd73xx ATM driver.
* by Zhicheng Tang, [email protected]
* 2000 (c) Texas Instruments Inc.
*
* 09/01/05 AV Adding Instrumentation code for some of the key functions.
* This can be enabled/disabled with the defining of the
* TIATM_INST_SUPP macro.(CQ 9907).
* 9/22/05 AV Adding support for the new LED driver in BasePSP 7.4. A new macro TN7DSL_LED_ACTION
* has been used to replace the direct calls to the old LED handler.
* UR8_MERGE_START CQ10450 Jack Zhang
* 4/04/06 JZ CQ10450: Increase Interrupt pacing to 6 when downstream connection rate is higher than 20Mbps
* UR8_MERGE_END CQ10450*
* 09/18/07 CPH CQ11466 Added EFM Support
