USB-C to Ethernet Adapter

[Roger M. Jenson]

After the August 2022 Milwaukee Linux Users Group (MLUG) meeting I
stopped at Best Buy and purchased a USB-C to Ethernet adapter so I can
use wired Ethernet networks on my devices that have USB-C ports. First
up was a Lenovo 10e tablet running ChromeOS. Plugged in the adapter,
connected an Ethernet cable, and it worked. Next up was my Pixel 5 phone
running Android. Turn off the WiFi, turn off cellular data, connected
the USB-C adapter with an Ethernet cable attached and  my phone
connected to my wired Ethernet network.

Hey y'all-

I have a nice Supermicro motherboard in my TrueNAS Scale server. I have tried two different NICs in the PCIe slots, and the OS can't see them. Both cards I tried take an SFP+ module, so they can be used for copper, fiber, DAC, whatever.

I tried the
lspci
and lshw commands, along with
ip address
and ip link

Strangely, dmesg seems to know it's there:
[Fri Aug 26 17:07:33 2022] QLogic 1/10 GbE Converged/Intelligent Ethernet Driver v5.3.66


I've also tried the cards in all slots it would fit in. The is a 2-socnnnnket board, and apparently the slots are driven by one or the other of the CPUs.  All this powering down and restarting so I can switch slots is really time consuming.

The board has four 1GB NICs on-board, and an IPMI port I've never been able to get working. Right now, I  a bond/team of some of the 1GB NICs using LACP on my Cisco switch.  IT supports dual Intel E5-2600(v2) Series Processors (Socket R LGA 2011) that offer QPI (Intel QuickPath Interface) Technology (V.1.1) and has the C606/C602 chipset.

By the way, the VGA card and the LSI SAS RAID card I have in the slots work fine. I've shuffled them around while trying the 10GB NIC in various slots. Theystill work fine, but the NICs are never visible.

The slots are (l-r)

• CPU1    Slot1    PCIe 3.0        x16
• CPU1    Slot2    PCIe 3.0         x4      in an x8 slot
• CPU1    Slot 3  PCIe 3.0        x16
• CPU2    Slot4    PCIe 3.0        x16
• CPU2    Slot5    PCIe 3.0        x16
• CPU2    Slot6    PCIe 3.0        x8

The last attempt was an HP NC523SFP 10GB Server NIC.

Motherboard:    SuperMicro X9DR3-LN4F+ with 2 each Xeon E5-2620, 2 GHz
O/S:             TrueNAS Scale on Debian 11.2
NIC tried:      HP NC523SFP 10GB Server NIC
NIC tried:      Emulex  OCe11102                 All pics I find online for this have it in green fiberglass board, but mine is blue.

I see some chatter about how the HP NIC uses the qlcnic driver:

01:00.0 Ethernet controller: QLogic Corp. cLOM8214 1/10GbE
Controller (rev 54)
    Subsystem: Hewlett-Packard Company NC523SFP 10Gb
2-port Server Adapter
    Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV-
VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+
    Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast
>TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-

But I can't figure out how they got that output and I can't make mine show it.

Someone else said it's a rebranded QLogic QLE3242

The HP site is really hard to search for drives, but I did find some drivers for "HPE QLogic qlcnic drivers" but only for Windows and Red Hat.

I also saw this:

Try toggling IO-SRV in BIOS/UEFI and/or toggle each add-on card's ROM enable/disable feature that controls it reporting during POST and/or toggle the force add-on card ROM in the mobo's BIOS/UEFI.

I don't see that option per se in my BIOS, but I'm going to look further.

Couple things

- Some cards do not show up if the SFP module is not inserted before boot

- Does the card itself have a bios/settings?

- Does the card show up during the bios startup..display a rom message or something like that?
