Fails to build against kernel 5.15.2-zen1-1-zen on arch linux

[skwerlman]

This broke when the ethtool coalesce api was extended in https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f3ccfda1931977b80267ba54070a1aeafa18f6ca

quick patch which fixed it for me:

a proper patch would need to have docs for the new params, and have version guards

[skwerlman]

even with the above patch, this is failing again on 5.17.1-zen1-1-zen:

[skwerlman]

i have a fork working on the latest kernel here: https://github.com/skwerlman/tn40xx-driver

note that it wont work for some older kernels because im lazy

[afrojewelz]

i can build under 5.16 pbo kernel without error after apply your 2 line patch ,but when i make install the tn40xx.ko kernel throws exceptions

by add #ifdef 5.15 kernel version do not support set/get_ringparam() ,5.15 can finally build this module only warning these to function did not use. even the ko can actually modprobe into kernel witout causeing kernel exception or hang, but still it is not working with NIC.

i was not a hardcore C developer,i m not quite sure what set/get_ringparam() do or did ,even it commented with # Report ring sizes. what 's the feature it provides so matter? if so matter , how to perfection these two functions?

[afrojewelz]

i ve managed successfully build tn40xx.ko on proxmox 5.15 for my QNAP Tehuti Networks Ltd. TN9710P 10GBase-T/NBASE-T Ethernet Adapter [1fc9:4027] and finally modprobe attached succesefully
i will share methods how to onmy repository
https://github.com/afrojewelz/tn40xx-driver/tree/tn40xx-003kvgt515
with another branch，this may only work for my NIC and i may not bare liability to broken your hardware.so if you still wanna try it, proceseds with cautions and thoughts

[devadattas]

Thanks this worked for my issue #53 as well.

I still have the issue. Already tried a few different repos.

My Card is Delock recognized as TN9510 RJ45 10gbe and i am trying to install on proxmox 7.4.3.
Can you help?

[cahz]

Maybe try https://github.com/cahz/tn40xx-driver on develop branch

[oktay89]

Are this the correct commands?
git clone -b develop https://github.com/cahz/tn40xx-driver.git /usr/src/tn40xx-004-cahz
dkms add -m tn40xx -v 004-cahz
dkms install -m tn40xx -v 004-cahz

Unfortunately still the same error:

[cahz]

Kernel 5.17 changed the ethtool_ops struct. Maybe try to checkout an older version (like cahz@562b596) which still uses the old struct.

since my QNAP qm2-2P10G1T card had to continue served,i update my repo branch tn40xx-003kvgt515 into tn40xx-qm2-2P10G1T also make it my default. most importanly it's worked for PVE 5.15.108.
https://github.com/afrojewelz/tn40xx-driver/tree/tn40xx-qm2-2P10G1T it' based on tn40xx-003 with header of marvel mv88x3310-phy header , added [cahz] tweakin for dkms ,many thx.
