PCI hotplug of the Network Interface Card (NIC) results in the interface name changing.


To avoid NIC name changes with automatically generated network interface names, create a custom udev rule that allows setting NIC names based on generic PCI addresses with wildcard domains by editing the "/etc/udev/rules.d/70-persistent-net.rules" file.


The change to the interface name can occur due to the relation between the PCI address and the interface names.

Additional Information

The below is an example udev rule that can be used to add entries for PCI devices that should be mapped to network interfaces:

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{dev_id}=="0x0",KERNELS=="*:01:00.0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

Observe the PCI address in the form of *:01:00.0, meaning its first component (called domain, 4-digit value) is stated as a wildcard expression.
