Background
I have a KVM that works with a custom Gaming PC, the last generation of Intel 16-inch MacBook Pro, a Pi4 B 8GB and an empty port for whatever I can think of next. The wireless in my house absolutely stinks so we've converted nearly everything to Wired Ethernet using switches.
Issue
I used the Pi's built-in GB Ethernet port until I burned up 1 of 2 the ethernet cables that took me forever to fish through walls etc. In an effort to save my second wall port/cable I forced link Negotiation down to 100MB using the Trendnet TU2-ET100, because the chipset is natively supported by the AX88772 kernel driver. I'm referring to the Ubuntu manpage because up until the new version(23.10), which I did a do-dist-upgrade for yesterday. After upgrading, the driver will not properly load. I'm not in front of my Pi right now, but dmsg reports something like failed to write error -110. I used PENS to downgrade to 22.04D and the issue still exists.
What happened between 22.04 and 22.04D, AKA 22.04D and 23.10 kernel-wise besides a version upgrade, and does anyone know how to fix it? I use Gentoo on a regular basis, so if I need to recompile a kernel I can. I've just never done it in a Debian based environment. Until I can fix this, I switched to Arch.
the Pi's built-in 5GB ethernet port- the what now? Are you suggesting the raspberry Pi's ethernet port caused damage to an ethernet cable? This is a wind up, right?1not a5) "built-in" ethernet port on the pi - still no idea why you think your raspberry pi 4 has built in 5 gigabit, and how you think that is at all relevant to the burning of a cable!!
