OFS : Data Path of QSFP from HE_HSSI

Hi Team,

I am using N6001 with Intel OFS (OFS PCIe Attach) . I wanted to test data transfer from Host1 to Host2 as below.
Host1 -> N6001(Port0) -> OtherNIC(Port0) -> Host2.
Is there any sample application available in OPAE/OFS which performs this transaction? Can you please suggest.

In addition to above query, I wants to know how HE-HSSI sends data to QSFP?. The hssi application shows "No eth interface, so not honoring --eth-loopback". ( https://ofs.github.io/ofs-2024.1-1/hw/n6001/user_guides/ug_qs_ofs_n6001/ug_qs_ofs_n6001/ Section 7. Send traffic through the 10G AFU). Does this mean the HE_HSSI will not communicate with E-Tile or QSFPs (FIM) ?

Do I need to enable any parameters to pass over QSFPs?

Thankyou.

Ofs

    Hi,


    Unfortunately that is not possible. The reason is that the DPDK is communicating to the E810 NIC controller directly through PCIe x4 interface.


    Thanks.

    Hi,


    Currently there is no way to run DPDK on this design as it. We do not have application or driver for it to show in the OS level such ipconfig command.

      Hi @JohnT_Intel ,

      I hope you’re doing well. I’ve noticed that there’s an IFPGA driver in DPDK designed for the N6000 & N3000. Would it be feasible to port this driver for the N6001 design with minimal modifications?

      Thank you for your insights!

      Hi @JohnT_Intel ,
      Thanks for the update.
      I will test and update the same.

      In addition to my queries, whether the ice driver will list any interface in Host for N6001? So that interface will list under 'ip a'/'ifconfig'. With this interface, can I create any application to send and receive packets from board to board without HSSI in-built application?. Is it possible to run DPDK application in this FIM?

      Best regards,
