Subject: [PATCH 2/7] bridge: keep MAC of first assigned port
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

original commit message:

Default bridge changes MAC dynamically using smallest MAC of all
connected ports (for no real reason). To avoid problems with ARP
we simply use the MAC of the first connected port.
