[ovs-discuss] MAC address question

I just noticed an that when I create a ovs switch with ovs-vsctl
add-br that the MAC address gets a 00:23:20 (Nicira Network) prefix,
which is expected, but when I add a physical card with ovs-vsctl
add-port <switch_name> eth0, the MAC address of eth0 is given to the
I am wondering if this is the intended behavior? If so why and can
there be a setting that leaves the switches MAC in tact? I know that
the xen network-bridge script does a similar trick, but goes as far as
taking all the networking settings of the ethN device as to try to
keep networking up even during bringing up a xen bridge device.
I'm wondering at a higher level will it be possible for me to write
openflow control rules that match on MAC address when working with the
case of 0 physical nics associated with the bridge and what about the
case where there is a network bond that gets attached, what would the
MAC address change to in that case?
All I really want to know for now is what the behavior is and that I
am accurately writing my rules to reflect that.
