Description alex hauras 2012-03-06 18:05:31 UTC 
using busybox 1.19.4:

iputils ip:
#/usr/sbin/ip link add link eth0.143 address 00:22:76:13:E8:C1 eth0.143e0 type macvlan
#ifconfig eth0.143e0
eth0.143e0 Link encap:Ethernet  HWaddr 00:22:76:13:E8:C1
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

#ip link del eth0.143e0

busybox ip:
#ip link add link eth0.143 address 00:22:76:13:E8:C1 eth0.143e0 type macvlan
#ifconfig eth0.143e0
eth0.143e0 Link encap:Ethernet  HWaddr D6:F1:73:D0:24:55
                                ^^^^^^^^^^^^^^^^^^^^^^^^ - random ether instead of specified one
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

#ip link del eth0.143e0

if we need to set address in busybox, we will need to specify it one more time:
#ip link set eth0.143e0 address 00:22:76:13:E8:C1
