Something really odd is going on in the last few rollings, from at least the August 26th on
My main VLAN trunk:
8: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether 00:02:c9:3f:2c:41 brd ff:ff:ff:ff:ff:ff
But that's the wrong MAC
ethernet eth0 { description "UNTAG" duplex "auto" hw-id "00:02:c9:3f:2c:40"
And then further down in that "eth0" block is another, that I definitely didn't put there.
hw-id "00:02:c9:3f:2c:41"
If I delete that, it shows back up after reboot.
It looks like all the interfaces have hw-id that's changed, either by adding " or by moving devices.
