Hi,
I am using intel X540 T2 ethernet adapter and trying to measure maximum throughput. A linux PC is used where X540 has been plugged into a PCIe slot.
I would not like to use TCP/UDP stack and instead do a direct Layer2 transfer.
Does ixgbe driver support any api where we can directly transfer data from a user buffer to NIC ?

Hello Hello AslamBablu,
Thank you for the patience on this matter.
Our engineers have suggested to check your query with Data Plane Development Kit (DPDK) team. The current ixgbe driver does not have the capability of what you are looking for therefore we would suggest checking this with DPDK regarding this query.
See the following for access to Intel Premier Support. Click the "Access and Log In" to contact the DPDK support https://www.intel.com/content/www/us/en/design/support/ips/training/welcome.html
Feel free to let us know if you have submitted query to DPDK so we can send a heads up as well.
Awaiting to hear from you.
Should there be no response from you, I’ll make sure to reach out after 3 business days.
Best regards,
Crisselle C.
