Hi Greg,

Thanks for maintaining these as always. For the first time in a long 
time, I booted the latest stable (6.15.x -> 6.16.3) and somehow lost my 
networking. It looks like there is a patch from Intel (reported by AMD) 
that did not make it into stable 6.16.

This asset is a quad-port embedded Intel NIC, previously eno1..4, now 
eno1np0, eno2np1, eno3np0, eno4np1.

Seems like there's a bit of a debate right now over should this get 
carried in the tree (this 1/4 state stuff is no good). Anyway, upgrading 
the kernel broke my networking, and because this is carried in 6.17-rc3 
for ixgbe it will break again. I honestly don't care if it's some 
ridiculous systemd thing or the kernel that fixes this, just that 
there's a note on how to migrate for the common man (and that there is a 
material change to how interfaces are exposed).

Kyle.
