ipv6 on 5.10 onboard ethernet driver crashes

raspberrypi/linux#4236

possible related: raspberrypi/linux#4485

actions taken:

-notified openwrt developers
-notified rpi-foundation ( existing issue beginning in march @ 5.10.17 )
-implemented local ethtool disable rx checksumming workaround in builds 3.5.x
-designating these builds as 'current' ( not-stable ) until resolved upstream or 5-7 (ipv6) build users test them without tailroom

if you test a 3.5.x build and run ipv6.. please report the result from

dmesg | grep tailroom | wc -l

after boot has fully completed (5mins)

anyone with wan connections over 300Mb/s would be best to stay on 3.2/5.4 builds for now if utmost bandwidth is a priority... although realworld hit from the workaround is not massive...

ethtool tx off fixing other issues on this one possibly related?

raspberrypi/linux#3577

afaik this issue is not present on 5.15 so moving to 23.05.x it IS GONE!!! YAY!!!!!

closing, and will remove the dmesg ethtool workaround once we know 22 is behind us... will free up a cycle or two ;)
