Why does the F-Tile Ethernet Multirate FPGA IP start transmitting invalid packets when the “i_p<n>_tx_rst_n” or “o_p<n>_rst_n” signals are deasserted?

Due to a problem in the Quartus® Prime Pro Edition Software version 23.4, the F-Tile Ethernet Multirate FPGA IP will transmit invalid packets when the “i_p<n>_tx_rst_n” or “o_p<n>_rst_n” signals are deasserted If the “Enable IEEE 1588 PTP” parameter is set and the “Link fault generation” parameter option is set to “Bidirectional”.
These invalid packets are not driven by the client interface.
The packets are typically 64 bytes long and only contain zeroes in all of the fields.
 

There is no work around to this problem. 

This problem is scheduled to be fixed in a future release of the Quartus® Prime Pro Edition Software.
