Reinstalled network-r8168 drivers using mhwd after updating
inxi -Na shows no r8168 driver loaded or available, only r8169
Network:
Device-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet
vendor: ASUSTeK P8 series driver: N/A modules: r8169 pcie: gen: 1
sudo modprobe r8168 fails to find driver
modprobe: FATAL: Module r8168 not found in directory /lib/modules/6.5.4-1-MANJARO
But pamac shows it is installed
$ pamac list -f linux65-r8168
/usr/lib/modules/extramodules-6.5-MANJARO/r8168.ko.xz
$ pamac search -f /usr/lib/modules/extramodules-6.5-MANJARO/r8168.ko.xz
/usr/lib/modules/extramodules-6.5-MANJARO/r8168.ko.xz is owned by linux65-r8168
I think you mean network-r8168. There is no network-r8169, because r8169 is already included in the kernel.
It will commonly only be loaded after a reboot.
It must be a bug in pamac (again), because…

System was rebooted twice for both kernels before reporting issue with linux65-r8168
Repository updates were installed via pacman as I expected any comment might be derided

So you do have r8168 installed. Well, then if it’s not loaded into the kernel and you do still want to stick with r8168 — for reasons I don’t understand, unless your hardware is very old — then you probably don’t have a blacklist on r8169 anymore.
So check /etc/modprobe.d for the blacklist file. If it’s not there and r8168 is installed, then the kernel will still use the native r8169 driver instead of r8168.

see post #1 for kernel v6.5
Then you know what to do. Ditch r8168 and use r8169. 
Following up on comments in other topics asking about kernel v5.15:
Reinstalling kernel via mhwd also installed r8168 driver no problem

As new version of r8168 driver is working for v6.1 and v5.15 kernels it probably also works for earlier LTS kernels 4.19; 5.4 and 5.10
Given that you have yet failed to provide any reasonable explanation as to why you insist on using the out-of-tree r8168 driver module when the in-tree r8169 driver clearly works flawlessly, I shall hereby take my leave from this thread.
