Hi!
I would like to know if anyone already has an opinion about this network adapter. It appears to be fairly new, listed since october 2017. But it allows using VLANs (802.1Q) and is available for around 100€. So their must be some drawbacks. It uses an Tehuti TN9510 Chipset. The specifications claim, that there is a Linux driver, but I guess it has not been incorporated into the Debian 9 distro yet. I am not afraid of adding the driver myself and testing the network adapter, especially as this is no production system, but I would like to ask for your opinion anyway. Am I running straight into trouble doing this? Shall I stick with Intel X550 chips?

Greetings

Hello again!
Well, I just tried that card, but I have troubles getting it to work on Linux.

Sidenotes:
  • It works on wWindows 10 with the Driver provided by the vendor Edimax
  • On the website of Edimax it says that Linux kernels from 2.6 to 4.14 are supported
Regarding the installation on Linux I tried the following:
  • Installed the NIC as sole expansion card to the first PCIe slot
  • Installed a naked Debian 9.5 to make sure it uses a not too fancy linux kernel (which is 4.9.0-7-amd64) in the suppoerted range of versions
  • Downloaded the driver (which is version 0.3.6.15) and unpacked it in my home directory, entered the folder tn40xx-0.3.6.15
  • I ran: m-a prepare (module-assistant), make, make install. No problems so far.
  • I added tn40xx to /etc/modules in order to load the module on startup. Restarted the maschine.
  • The module was loaded, but the NIC did not show up. Well, the NIC did according to lspci, but the kernel module neither loaded or in use.
  • I also tried using dkms:
    git clone -b release/tn40xx-001 https://github.com/acooks/tn40xx-driver.git /usr/src/tn40xx-001
    dkms add -m tn40xx -v 001
    dkms install -m tn40xx -v 001
    Again, with no effect.
  • I also tried to manually bind the device to the driver using:
    echo 0000:01:00.0 > /sys/bus/pci/drivers/tn40xx/bind
    Which gave me an error that no device could be used (dt.: "kein passendes Gerät gefunden")
Current console outputs:

Hi!
I can't remember exaclty if I verified that yesterday, but I think it is loaded.
I will post a definite answer in the evening, but I tried this method before on a different system and the kernel module did load. (Well, I guess I forced it to do so by adding it to /etc/modules. And then I found the message "tainted kernel", which is to be expected from proprietary drivers afaik. I think I optained it via dmesg | grep tn40xx. Aah, and there was no error or other warning tn40xx.)

Does the driver load?

# modprobe tn40xx
Click to expand...

  • modprobe tn40xx
    gives me no return
  • sudo lsmod | grep tn40xx
    returns
    tn40xx 466944 0
    where the 0 is in the column "uses"
So, does that mean it is loaded but not used by any device?

Now that's interesting: dmesg shows the network driver...
Code: 
[    3.195752] tn40xx: loading out-of-tree module taints kernel.
[    3.196449] Tehuti Network Driver, 0.3.6.16.1
... BUT what I downloaded and installed from the Edimax Homepage was labelled as version 0.3.6.15 and not 0.3.6.16. What is going on there?

And it does not mention the device name anywhere. No TN9710P nor Edimax, nothing. I also checked for Ethernet:
Code: 
sudo dmesg | grep eth
[    2.334905] e1000e 0000:00:19.0 eth0: (PCI Express:2.5GT/s:Width x1) 10:78:d2:a9:70:75
[    2.334908] e1000e 0000:00:19.0 eth0: Intel(R) PRO/1000 Network Connection
[    2.334951] e1000e 0000:00:19.0 eth0: MAC: 9, PHY: 9, PBA No: FFFFFF-0FF
[    2.339545] e1000e 0000:00:19.0 eno1: renamed from eth0

What does that mean? More specifically: If lspci sees the device and it works perfectly fine in Windows, the hardware is functional and accessible. In which step of the linux boot process does the kernel decide, that this piece of hardware is not worthy of being recognized as a "device" and especially not of being assigned a driver?

Thanks for your help!
Kind regards

Features of Edimax EN9320TX-E


This fulfills the high-performance demands like large file transfers and HD video editing, which uses high-definition shared storage platform to possess enhanced server functionality and network functionality.
Joining the EN-9320TX-E using all the RJ45 cable, your system immediately updated to exceptional performance in quickly and reliable10Gbps high-speed. The EN-9320TX-E is an perfect choice to improve your server or workstation as the high performance, low-power intake and better-quality remedy to match the demands of low latency, higher bandwidth, high-throughput and cheap Gigabit Ethernet Adapter. The installation process is very easy I followed the guidelines mentioned on https://howtotechh.com/firestick-ethernet-adapter/.

10GbE Superior Network Rate
Equipped with a single 10 Gigabit RJ45 port, the EN-9320TX-E is capable of supplying 10 times greater performance than existing Gigabit transmissions. The adapter is a readily competent server NIC of the own networks which supports up to 2000Mbps full-duplex bandwidth capability. Together with the PCI Express rev. 2.0 specification x4 Interface, the EN-9320TX-E supplies an optimum PCI Express upgrade alternative to the primary board.


The EN-9230TX-E was created with high-speed PCI Express bus architecture which includes innovative features and
safety. What's more, it can divide devices within each VLAN from the rest of the
system for better traffic management. This provides flexible functionality while using a secure and easy network
atmosphere. Additionally, the EN-9320TX-E supports additional innovative features like 16K Jumbo Frame to maximize the throughput and IEEE 802.3x ray Control, which prevents dangers of package loss for the best performance in data transfer.
