Would it be possible to sysupgrade from an image built from adron's repo to a 5.15 image from robimarko's rb5009-5.15 branch, or would one need to start over with the initramfs? Would it work to modify /lib/upgrade/platform.sh to make platform_do_upgrade() use default_do_upgrade and then sysupgrade?
Not yet, sorry. I have been hit by various other issues around the house. First, our cooktop stopped working and spare parts or a replacement are close to impossible to procure in a timely manner. And now the heating also stopped due to a bad NTC. I soldered another one in place which kinda works still trying to figure out proper B value and stuff... Luckily, we have a modern heat pump and are not reliant on gas or oil like much of the rest of Europe!
I have the impression it's pretty stable, I haven't put it into production. 2,5G is still an issue AFAICT. The QCA8081 NIC won't work at 2,5G (link shows at the other end, correct speed, but no ping or other connectivity), will work with 1G.
I can't comment on the 5.10 tree but I'm running 5.16 on mine as my primary home router and I think all of the important bits are backported so I think the OpenWRT port should be good. Not using 2.5G or the SFP+ port yet, but driving my 500M connection just fine.
Frankly I find it easier to just apply adron's patches on top of a current master (or the 22.03 branch if you'd like). Master has the first patch already integrated.
Tried to modify the question but completely deleted it ! (never correct and drive) But yes I was looking for the SWITCH/VLAN section on adron's build. Thanks for the reply. Found it
I got my Zen 3 CPU, so I'll be able to test with the RTL8125B 2,5G NIC on my B550 motherboard soon, although I do not expect it to behave any different than the other multigig connections I have around. Just for anyone interested in looking into the QCA8081 .
