bus id match

[Michal Filka]

Hi,

I've problem with following rule (simplified as much as possible):

# replaced 70-persistent-net.rules
SUBSYSTEM=="net", KERNELS="0000:00:19.0", NAME="eth1"

# udevadm test --action=add /sys/class/net/eth0
(snip)
rename_netif: changing net interface name from 'eth0' to 'eth1'
rename_netif: error changing net interface name eth0 to eth1: Device or
resource busy
(snip)
UDEV_LOG=6
DEVPATH=/devices/pci0000:00/0000:00:19.0/net/eth0
INTERFACE=eth0
IFINDEX=2
ACTION=add
SUBSYSTEM=net
ID_VENDOR_FROM_DATABASE=Intel Corporation
ID_MODEL_FROM_DATABASE=82566DC Gigabit Network Connection
ID_BUS=pci
ID_VENDOR_ID=0x8086
ID_MODEL_ID=0x104b
ID_MM_CANDIDATE=1
SYSTEMD_ALIAS=/sys/subsystem/net/devices/eth1
TAGS=:systemd:

So, the device is named correctly (eth1), but what about that rename_netif
errors? Is that a problem?

You can't rename network interfaces in state 'UP'.
That only works for unconfigured interfaces.

Cheers,
