Subject: Re: r8169 unknown chip XID 688
HI ,
installed the patch on a debian-backports 6.10.11 kernel in a VM (KVM)
with the realtek injected using pci pass through.
i had to modify the patch a bit, removing the RTL_GIGA_MAC_VER_63
related entries because these don't seem to be in this kernel
running this kernel gives me this result now
