So here's how i got it to compile on kernel 6.13.8

source of some of the patches

basically all of the patches in the forum (last comment) + my one

combopatch_linux6.13.8.patch

here's my change to the patches in the forum

upgrade to linux6.7.2 and upgrade driver version to 1.038.02

I try the patch created by @jghodd below, it cannot patch successfully, and I don't understand the effect of function 'dma_free_coherent', so I just upgrade the source code and make it to build success base on refactor log in kernel repository

linux672.patch

r8101 is not building against the 5.18.x kernel in a 32-bit environment. to get it to install, i had to create an additional patch for 5.18.x (as well as continuing to use the linux517 patch file). i modeled my code changes on similar updates made to r8168-dkms. here's the linux518.patch file. if anyone can improve on it or add to it, please let everyone here know.

you can set pkgrel to whatever you want - i needed it to be 1.4.

Edit: just an FYI that I had to add the eth_hw_addr_set call to the patch (kinda important)

here's a patch for r8101-1.035.03 that follows the pattern used to patch r8168 (linux517.patch):

the r8101 dkms module no longer builds under linux-5.17.

I'm trying to use this instead of r8169 because r8169 seems to not manage to connect at > 100Mbps.

My hardware is identified as "RTL810xE PCI Express Fast Ethernet controller", yet the driver seems to not pick it up: https://pastebin.com/eHfkLjWU

Has anyone encountered a similar issue?

I've updated the package.

Worked correctly with this modification to the build file:

Replace: ("${url}/${_pkgbase}-${pkgver}.tar.bz2" With this: ("https://fichiers.touslesdrivers.com/64215/r8101-1.035.02.tar.bz2"

They seem to keep the drivers up to date here: https://www.touslesdrivers.com/index.php?v_page=12&v_code=668#23 so worth checking for a new version if you're going to use this.
