It could, do we want and need to, no. You have the Ethernet alias in /sys/class/net/*/device/uevent already that would allow you to perform that (re)naming in user-space: # cat /sys/class/net/eth0/device/uevent DRIVER=bcmgenet OF_NAME=ethernet OF_FULLNAME=/rdb/ethernet@f0480000 OF_TYPE=network OF_COMPATIBLE_0=brcm,genet-v5 OF_COMPATIBLE_N=1 OF_ALIAS_0=eth0 <================== MODALIAS=of:NethernetTnetworkCbrcm,genet-v5 -- Florian
