If you have Fedora 18 with updates applied your systemd is new enough to
allow you to see the udev-generated names using:
udevadm info --export -p /sys/class/net/$IFACE | grep ID_NET
Example output:
E: ID_NET_NAME_MAC=enx000f53014229
E: ID_NET_NAME_PATH=enp40s0f1d1
E: ID_NET_NAME_SLOT=ens4f1d1
What happens with USB network devices that are plugged into different
slots? Currently my iPhone shows up as eth1, but using the above,
depending on which of two adjacent ports I happen to plug it into, I get:
$ udevadm info --export -p /sys/class/net/eth1 | grep ID_NET
E: ID_NET_NAME_MAC=enx0226b08178a9
E: ID_NET_NAME_PATH=enp0s29f7u1c4i2
$ udevadm info --export -p /sys/class/net/eth1 | grep ID_NET
E: ID_NET_NAME_MAC=enx0226b08178a9
E: ID_NET_NAME_PATH=enp0s29f7u2c4i2
Will those be treated as two separate devices under this scheme
depending on which USB port I happen to use? And if so, will that
actually matter?
