The realtek target supporting the Realtek switches is the only target in
OpenWrt main still on Linux kernel 5.15, all other targets are at least
on kernel 6.1, most of them are on Linux kernel 6.6.

The next OpenWrt major release will use kernel 6.6 only, all targets not
migrated to kernel 6.6 will get removed from OpenWrt before branching.
Looking at the status of OpenWrt main branch we will probably branch in
the next 2 months.

Here is the overview of the Linux kernel 6.6 migration status:
https://github.com/openwrt/openwrt/issues/15192

There is a pull request to drop the realtek target from OpenWrt main:
https://github.com/openwrt/openwrt/pull/16052

A migration of the realtek target to Linux kernel 6.1 was started here:
https://github.com/openwrt/openwrt/pull/12726


I noticed that #15192 metions
https://github.com/howels/openwrt/commits/realtek-6.6-test/ as the
development branch. Is anyone coordinating that front? Is there a TODO
list? I have some devices to play with (dgs-1210-28p and dgs-1210-52p)
and I can give a hand on specific topics but I do not have too much
time to lead it. There are some commits in that dev branch that are
actually disabling things. I might be able to work on fixing those
things or check what is useful from the 6.1 PR. However, I don't want
to step over someone's WIP and waste time in useless rework.

I acquired an HP 1920-24G and gave this branch a spin. Unfortunately, itdoes not boot with this branch. Booting 23.05.4 and current main branchare fine.
