When following the reset procedure, stat_tx_local_fault for a
particular port does not assert while the PHY is in reset. AMD
recommends using stat_tx_local_fault to ensure that the MAC is
initialized and the port is clear. Use the following procedure:
- Assert
tx_core_reset,tx_channel_flush(all six ports), andtx_serdes_reset(all six ports). - Release
serdes_resetfor active ports. - Release
tx_core_reset. - Wait for
stat_tx_local_faulton active ports. - Release
tx_channel_flushfor active ports.
