bond: T7571: fix inconsistent MAC address behaviour
After upgrading from VyOS 1.3 to 1.4, there is an inconsistent behavior with
MAC address assignment on bonded interfaces. In VyOS 1.3, bond interfaces used
a hardware MAC address from one of the member interfaces. In 1.4, a synthetic
MAC is used by default - generated by the Linux Kernel.
Oddly, setting mode 802.3ad (which is also the default) temporarily causes the
hardware MAC to be used again - until a reboot, after which the synthetic MAC
returns.
Deleting the mode config again causes the hardware MAC to be used. This
inconsistent behavior has caused issues with MAC-based filtering in networks.
The fix is to retrive the hardware MAC address from the first bond member
interface and use set it explicitly for the bond interface.
