OFS : Data Path of QSFP from HE_HSSI

[attdoner]

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.

Hi @JohnT_Intel ,
Can you provide the programming log of 100g. I want to cross verify the method of programming, to check whether I missed out any steps. I was not able to get the above log prints in 100g. Instead it used to get mbox_write

Hi,

I do not have issue on clearing the HSSI STAT from my side.

Below is my logging.
