Subject: man/systemd.netdev: adjust documentation of MAC addresses for bridges
X-Git-Tag: v250-rc1~643^2

man/systemd.netdev: adjust documentation of MAC addresses for bridges

In the past bridge devices used to be created with a generated MAC address
thwarting the inheritance of the first slave's MAC address. This has been
changed by commit [1] some time ago. Reflect that behavioral change in the
documentation.
