Serial RapidIO gen2 v4.0 - LPM attributes are used but rxlpmen is set to '0'

Description

Serial RapidIO v4.0 has GT wrapper ver1.5 rev.2 which uses LPM mode for RX equalization.

Earlier versions used DFE mode.

However, gt_rxlpmen_in is still tied to '0' in the GT wrapper.

Solution

For LPM mode, a value of '1' should be used for gt_rxlpmen_in in the gt_gthe3_channel_wrapper file.

This value will be fixed in Vivado 2015.4.
