Description Dusty Mabe 2020-11-16 18:36:57 UTC 
Description of problem:

This is a downstream bug with corresponding upstream bug: 
https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/issues/581

It's common to name a vlan device in the DEV_PLUS_VID form. For example: eth0.100
This seems to throw off the nm-initrd-generator. Here's an example:

```
[core@localhost ~]$ /usr/libexec/nm-initrd-generator -s -- ip=eth0.100:dhcp vlan=eth0.100:eth0 
NetworkManager-Message: 18:35:19.274: <warn>  [1605551719.2744] cmdline-reader: Unrecognized address: eth0.100
NetworkManager-Message: 18:35:19.274: <warn>  [1605551719.2745] cmdline-reader: Ignoring peer: dhcp (not implemented)
