TSE MAC - disabled promiscuous mode does not filter packets

From my customer: Our QSys configuration for the Cyclone 10 LP includes Nios II, on-chip RAM, FIFOs, mSGDMA, TSE MAC to an external PHY (Marvell 88E1510). Is there something else needed to disable ...

Hi,

Your understanding is correct that the control bit for promiscuous mode is on command_config.PROMIS_EN (bit 4)

  • bit 4 = 1 (enable)
  • bit 4 = 0 (disable)

Attached is the screenshot of expected behaviour from TSE IP user guide doc for your reference. You can cross check it with your design.

One way to debug your issue would be to try out FPGA TSE MAC or PHY internal loopback feature to validate the expected function first. Once proven working, then you will know there could be some issue with external PHY or secondary NIC card.

Thanks.
