Why do I see stability problems with the dynamic reconfiguration design example which uses the F-Tile Ethernet Multirate FPGA IP with FGT PMAs in external loopback?

Description

Due to a problem in the Quartus® Prime Pro Edition Software version 22.3, the dynamic reconfiguration design examples that use the F-Tile Ethernet Multirate FPGA IP in external loopback with FGT PMAs may experience stability problems.

Depending on the exact multirate variant you are using, these problems might manifest themselves as packet count mismatches, PTP accuracy failures, PTP ready timeouts, PTP initialization failures, unexpected PTP status register values, RX PCS ready timeouts, RX FEC lock failures or RX packet valid timeouts.
