Hello,

I have two identical HP servers running Debian 9.  One of them is a clean
install of 9, whereas the other was upgraded from Debian 8.

The one that was upgraded has no networking issues (indeed, it still uses
the ethX interface names).  However, the one that was installed from
scratch is having an issue which I can't seem to figure out.  There are 4
network interfaces -- eno[1-4] -- but they are all getting mapped to eth0.
It looks like they were mapped correctly until I reloaded the network
driver a few days ago.  Any idea how I can get them back into a 1:1 mapping
with the actual physical interfaces, instead of all pointing to the same
one?

Some dmesg output for reference:

Looks fine, but then...

I should note that this server is now in production, so it would be
fantastic if I can solve this without taking down eno1 as that is the
primary network link.  Any help is greatly appreciated.

Thanks!
