Hi Greg

6.16.3-rc1 compiles on x86_64 (Xeon E5-1620 v2, Slackware64-15.0),
and boots & runs on x86_64 (AMD Ryzen 5 7520U, Slackware64-current).

No regressions observed, apart from the one already mentioned for
6.16.2-rc1.
Thus I tested 6.16.3-rc1 with V3 of the patch and it seems to work ok:

Yeah, that one needs to get into Linus's tree, hopefully soon...

Re: 6.16.3-rc1 review

[Brett A C Sheffield]

UDP broadcast is broken in this kernel - the destination ethernet address field is mangled. See:

 https://lore.kernel.org/regressions/20250823121336.18492-4-bacs@librecast.net/

As this is bug-for-bug compatible with mainline, I believe stable policy is to
wait until this is fixed there before backporting a fix.

All other Librecast network tests passing.
