I can't reproduce these three.

Do you have systemd-networkd running? If so, by default it tries to
take over interfaces unless you tell it not to. For example, on my
system I have:

$ cat /etc/systemd/network/10-ignore.link 
[Match]
OriginalName=*

[Link]
MACAddressPolicy=none

This tells systemd not to assign a persistent MAC address on virtual
interfaces.

And (redacted):

$ cat /etc/systemd/network/80-dhcp.network 
[Match]
...

This tells systemd to only manage the interfaces matching the match
criteria and ignore the rest.

Fixed these three.

Can't reproduce these.
