I use static IP for my wired connection controlled via Network Manager.



ip link show enp4s0



2: enp4s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq state DOWN mode DEFAULT group default qlen 1000


NO-CARRIER would seem to indicate a driver issue as I'm posting this on the same pc by selecting the 4.18.0.17 prior kernel in grub.
NetworkManager.service and avahi-daemon.service are both LOADED and ACTIVE.



But NetworkManager not happy as shown ...

Could it be the wrong phy driver selected or Network Manager bug ?



"ip link set enp4s0 up" doesn't help.
