10GBase-T/NBase-T Ethernet Adapter not recognized - Trendnet TEG-10GECTX Version 2.0R

[Unraider2020]

Not sure if this isn't included in 6.9.0-rc2 or not but I tried to install this PCI Express 10GbE NIC and can't find it listed as an ethernet adapter.

 

I did see this in the lspci logs:

 

04:00.0 Ethernet controller [0200]: Tehuti Networks Ltd. TN9710P 10GBase-T/NBASE-T Ethernet Adapter [1fc9:4027]
    Subsystem: Tehuti Networks Ltd. Ethernet Adapter [1fc9:3015]
    Kernel modules: tn40xx

 

Is there something I need to do to enable the NIC? Or does the driver need to be included in the kernel to function?

Please post the diagnostics: Tools -> Diagnostics

Sure, thanks!

There is a driver, but it's crashing and failing to initialize:

 

Feb  8 13:55:57 Towerd kernel: tn40xx: MV88X3310 initdata applied
Feb  8 13:55:57 Towerd kernel: tn40xx: MV88X3310 I/D version is 0.3.4.0

Feb  8 13:55:57 Towerd kernel: tn40xx: probe of 0000:04:00.0 failed with error -22

 

Can't tell you if it's a driver or NIC problem though.

[Unraider2020]

I tried the NIC in a Windows 10 PC and it seems to work (at least at gigabit speed; I can't test 2.5 / 5 / 10 gbit yet).

 

Could it be the same problem this person was having?

 

 

According to the last post, there was a driver included in 6.8 that is no longer included in 6.9?

 

Thanks!

There is a driver in the latest 6.9-rc, but possibly it has issues, you could try v6.8.3 to see if it works.

[Unraider2020]

Thanks, I tried 6.8.3 and it worked, but when I went back to 6.9-rc2 it was also working. The only difference was that I used the top PCIe slot this time instead of the bottom one. Not sure what I learned but appreciate everyone's help!

[Unraider2020]

I think support was dropped again for the latest Unraid 6.9.2? In general, is this the kind of thing that will constantly be iffy (if the device manufacturer doesn't update linux drivers often enough)? Or is there hope that eventually a stable version will carry through for some time?

From the release notes:

These drivers are omitted:

Highpoint RocketRaid r750 (does not build)

Highpoint RocketRaid rr3740a (does not build)

Tehuti Networks tn40xx (does not build)

 

It's always a possibility when the driver is not included with the kernel, nothing LT can do about it but wait for a newer driver.

Is it possible to use 3rd party drivers like https://github.com/acooks/tn40xx-driver to workaround Marvell failure to support pro series products ?
