Looks good Jeremy.

I used the latest iproute2 package ip link command to set the VF MAC addresses 
on two 82599EB 10Gig ports named eth3 and eth4:

/usr/sbin/ip link set eth3 vf 0 mac 00:01:02:BA:BB:00
/usr/sbin/ip link set eth3 vf 1 mac 00:01:02:BA:BB:01
/usr/sbin/ip link set eth3 vf 2 mac 00:01:02:BA:BB:02
/usr/sbin/ip link set eth3 vf 3 mac 00:01:02:BA:BB:03

/usr/sbin/ip link set eth4 vf 0 mac 00:01:02:BA:BB:40
/usr/sbin/ip link set eth4 vf 1 mac 00:01:02:BA:BB:41
/usr/sbin/ip link set eth4 vf 2 mac 00:01:02:BA:BB:42
/usr/sbin/ip link set eth4 vf 3 mac 00:01:02:BA:BB:43

I can then show the output with the ip link show command:

ip link show eth3
6: eth3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000
    link/ether 00:1b:21:3c:a3:1c brd ff:ff:ff:ff:ff:ff
    vf 0 MAC 00:01:02:ba:bb:00
    vf 1 MAC 00:01:02:ba:bb:01
    vf 2 MAC 00:01:02:ba:bb:02
    vf 3 MAC 00:01:02:ba:bb:03

ip link show eth4

7: eth4: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000
    link/ether 00:1b:21:3c:a3:1d brd ff:ff:ff:ff:ff:ff
    vf 0 MAC 00:01:02:ba:bb:40
    vf 1 MAC 00:01:02:ba:bb:41
    vf 2 MAC 00:01:02:ba:bb:42
    vf 3 MAC 00:01:02:ba:bb:43

Load the ixgbevf driver in a guest it uses the correct MAC address and passes 
traffic.  I'll do some more thorough testing but so far looking good.

Please let me know when it's merged to your xen/stable-2.6.32.x branch and I'll 
keep working from that tree.  I have other work on deck for further VSI and EVB 
configuration work in the kernel that I'll want to port into your tree after I 
get it accepted upstream.

Thanks,

- Greg
