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.
LSPCI info for the cards (if you want the full output please let me know -
it's extremely long so I clipped it)

This is a new card, the X710-T2L we swapped in, so I haven't flashed its
firmware yet, the others have version 20 on them with no change.
Any pointers or assistance is greatly appreciated. Otherwise we're looking
at July for availability of X550s on a PCIe card from Dell.
