This appears to still be an issue on the latest 5.4.0-99-generic kernel.
I'm using a 2 port 10GSFP+ card. The PCI driver isn't bound according to
lspci, and the interfaces don't show up in dmesg or "ip link".
# lspci -nnk
31:00.0 Ethernet controller [0200]: Intel Corporation Ethernet Connection X722
[8086:37cc] (rev 09)
DeviceName: 10Gb Ethernet1
Subsystem: Lenovo Ethernet Connection X722 [17aa:4021]
# modinfo i40e
...
version: 2.8.20-k
description: Intel(R) Ethernet Connection XL710 Network Driver
...
vermagic: 5.4.0-99-generic SMP mod_unload modversions
Strangely the ports don't even come up with the latest 5.13.0-28 kernel.
# modinfo i40e
(no version)
vermagic: 5.13.0-28-generic SMP mod_unload modversions
The card works perfectly in another distribution with the i40e driver,
but that's running a 4.18 kernel.
