Can verify this bug on a single host (VM) using the dummy driver:

modprobe dummy
ip link add dummy0 type dummy
ip link add dummy1 type dummy
ip link set dummy0 down
ip link set dummy1 down
ip link set dummy0 master bond-test
ip link set dummy1 master bond-test
ip link set dummy0 up
ip link set dummy1 up
ip link set bond-test up
ip addr add 10.99.99.1/24 dev bond-test

ip -br -c a
