Yup, looks like the device addr for child interfaces isn't being set
correctly; compare:

    # ip addr show ib0
    13: ib0: <BROADCAST,MULTICAST,UP> mtu 2044 qdisc pfifo_fast qlen 128
        link/[32] 00:04:04:04:fe:80:00:00:00:00:00:00:00:02:c9:01:07:8c:e4:61 brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff

vs.

    # ip addr show ib0.8001
    15: ib0.8001: <BROADCAST,MULTICAST> mtu 2044 qdisc noop qlen 128
        link/[32] 00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00 brd 00:ff:ff:ff:ff:12:40:1b:80:01:00:00:00:00:00:00:ff:ff:ff:ff
    
I should have a patch fairly soon.
