I'd see if you can press your Intel reps into getting you the 550s or
the 800-series NICs for the unnecessary troubles it's a much nicer
design.
It's surprising they are shipping new cards with that old of a
firmware, you should be on 8.50 for the driver you are running
(https://www.intel.com/content/www/us/en/download/18635/non-volatile-memory-nvm-update-utility-for-intel-ethernet-adapters-700-series-linux.html).
Doing the FW update is worth a shot but most issues I've seen have
been driver related and you are running a pretty recent driver.

Kevin

I'm at my wits end with this, Citrix is stumped, Dell is stumped, and with
the supply chain issues the way they are we can't just yank these out in
favor of X550s. The problem is we have a group of Dell R740s with X710
dual-port NICs and the performance is, in a word, awful. Like 5-6 megabit
upload and 250 megabit download awful. However, identical server hardware
with any other card, be it a Broadcom or an Intel X550T, no issues. We can
get line rate all day long. The latest attempt was swapping the X710 for a
newer X710-T2L-t, which performed maybe 5-10 percent better. We've tried
three different driver revisions, firmware, BIOS, all the available
Hypervisor updates, it still performs the same.
The servers in question have X550s on the motherboard mezzanine card which
perform fine, and a single dual-port X710 in the PCIe riser. The X710 is
set up with an LACP pair trunked with three VLANs tagged across it. In
this pool we also have servers with X550s on the PCIe cards, and
Broadcoms. All those with an identical configuration perform without
issue, it's only the X710s that show this problem.
Hi Matt, sorry to hear about this problem. Let's poke a bit (please be
patient with me) and see if we can help you.
Have you followed the steps like located here:
https://www.thomas-krenn.com/en/wiki/Intel_Ethernet_700_Series_LACP_Configuration
As there are definitely known problems with LACP mode and the driver's
default settings.
You can try the above workaround and see if it helps. If that does help,
then there are ways to make the settings get applied by ethtool as the
system comes up.
Please let us know how it goes.
It would be helpful to know what kernel you're running, just for good
measure.
