Ethernet 1000BASE-X PCS/PMA or SGMII - 7-Series - Link does not come back up after Cable pull/replug or link partner reset

Description

After a cable unplug/replug or link partner reset, GTRXRESET might need to be issued to reset the transceiver and reset the RX CDR.

Solution

In the core_name_transceiver.v/vhd file, change dont_reset_on_data_error_in from '1' to '0'.

If PRBS logic from the transceiver debug ports is used, this input should still be driven high when Rx PRBS is enabled.
