[Intel-wired-lan] [i40e][PLP reording frame]

[Joerg.Hunsche at elektrobit.com]

Hello,
we use INTEL X710-DA2 with i40e-2.10.19.30.
Configured socket flags SOCK_RAW and socket option PACKET_QDISC_BYPASS to bypass queuing, sending single-threaded.

When sending PLP-Ethernet-frames we observe a problem, that after ~2h a PLP-Ethernet-frame is send about 250frames later than it should be.
Our assumption is, that somehow more than one TX-queue is used, what we have to avoid.

Is there any configuration of the driver possible configuring a single Tx-queue?
Is there any means to get the driver to a state that only a single Tx-queue is used?

Thank you for your support.
