Bringing the discussion to the list.
You stated you see the following on your Lenovo ThinkPad T470s with
UEFI firmware N1WET41W (1.20 date: 10/17/2017):
core_udp_sendto: stalling on configure with no mapping
OUI 54-E1-AD
lspci -s 0:1f.6 -v
00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (4)
I219-V (rev 21)
Subsystem: Lenovo Ethernet Connection (4) I219-V
Flags: bus master, fast devsel, latency 0, IRQ 125
Memory at dc200000 (32-bit, non-prefetchable) [size=128K]
Capabilities: [c8] Power Management version 3
Capabilities: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+
Capabilities: [e0] PCI Advanced Features
Kernel driver in use: e1000e
Kernel modules: e1000e
This might be the only wired NIC but there's possibly multiple device
handles to it and possibly a device handle to the wrong NIC
(wireless).
In your EFI shell (hopefully you have such an option):
version > fs0:\efi-ver.txt
dh -p Net > fs0:\efi-dh-net.txt
Feel free to run it without the redirect (">") to see the results
yourself. The redirects would help if you can access the files so you
don't need to manually transcribe the output.
Here's some other UEFI Shell commands that may be of use:
guid > fs0:\efi-guid.txt
or alias > fs0:\efi-alias.txt
dh > fs0:\efi-dh.txt
