Description

Hi

To support the new ReTX G.998.4 being adopted by some of the main euro isp's at the moment # bReTXEnable may be needed to be added to dsl_control?

Also in drv_dsl_cpe_api.c bRetTXEnable = DSL_TRUE; to added ?
To avoid issues with RTX_FORCED parameter

++pContext->lineFeatureDataCfg[DSL_UPSTREAM].bRetTXEnable = DSL_TRUE;
++   pContext->lineFeatureDataCfg[DSL_DOWNSTREAM].bRetXEnable = DSL_TRUE;

Currently any vrx based modems will have issues tying to connect to a G.INP profiled line with RTX_FORCED parameter.

1.1.13 Retransmission Mode (RTX_MODE)
The RTX_MODE is a configuration parameter used to control activation of retransmission during initialization.
This parameter has 4 valid values:

0: RTX_FORBIDDEN: ITU-T G.998.4 retransmission not allowed.
1: RTX_PREFERRED: ITU-T G.998.4 retransmission is preferred by the operator.
(i.e., if ITU-T G.998.4 RTX capability is supported by both XTU's, the XTU's shall select ITU-T G.998.4 operation for this direction).
2: RTX_FORCED: Force the use of the ITU-T G.998.4 retransmission.
(i.e., if ITU-T G.998.4 RTX capability in this direction is not supported by both XTU's or not selected by the XTU's, an initialization failure shall result).
NOTE – Due to the optionality of ITU-T G.998.4 retransmission in upstream direction, the use of RTX_FORCED in upstream may lead to initialization failure, even if the XTU is supporting ITU-T G.998.4 (in downstream).
3: RTX_TESTMODE: Force the use of the ITU-T G.998.4 retransmission in the test mode described in clause 10.4.
(i.e., if ITU-T G.998.4 RTX capability is not supported by both XTU's or not selected by the XTU's, an initialization failure shall result).

Thanks as always to John for continued work with lantiq based devices!
