I see. I didn't know how it picked it. Have you tried the following commands:
ifconfig br0 hw ether 00:0a:e7:2c:44:2a
or
ip link set br0 address 00:0a:e7:2c:44:2a
one issue might be that you need to change it before the interface is
brought up. The page where I got these commands (
http://backreference.org/2010/07/28/linux-bridge-mac-addresses-and-dynamic-ports/
) suggests using:
post-up ip link set br0 address 00:0a:e7:2c:44:2a
in your /etc/network/interfaces. Up not sure you'd want to do it after
it's up. Maybe use pre-up instead? Don't know...just guessing (my
master backend is busy the rest of the evening, so I can't experiment
on mine)
