To get the current configuration for an X4 series Ethernet adapter:

  1. List the AMD Solarflare PCIe devices:
    # lspci -D -d 1924:
    0000:01:00.0 Ethernet controller: AMD Solarflare Device 0c03
    0000:01:00.1 Ethernet controller: AMD Solarflare Device 0c03
  2. Confirm that you can see the X4 series that you want to examine, and note the PCIe address of its first interface.

    In the above example, the address of the first interface is 0000:01:00.0.

    Note: The PCIe address includes the domain (0000) before the bus, device, and function (01:00.0).
  3. Use devlink to get health diagnostics for the PCIe address that you noted in step 2:
    # devlink health diagnose pci/0000:01:00.0 reporter nvcfg-active

     port_mode = [1x1/10/25/40/50/100G][1x1/10/25/40/50/100G]
     firmware_variant = auto
     vf_count = 0
     msix_limit = 2048
     vf_msix_limit = 1
     vi_count = 8192
     rx_dc_size = 64
     tx_dc_size = 16
     rx_event_merge_timeout = 1500
     rx_event_merge_max_events = 15
     tx_event_merge_timeout = 1400
     tx_event_merge_qempty_timeout = 700
     tx_event_merge_max_events = 15
