The SWITCHDEV_ATTR_ID_BRIDGE_AGEING_TIME attribute is only emitted from:
sysfs/ioctl/netlink
-> br_set_ageing_time
-> __set_ageing_time
therefore not at bridge port creation time, so:
(a) drivers had to hardcode the initial value for the address ageing time,
because they didn't get any notification
(b) that hardcoded value can be out of sync, if the user changes the
ageing time before enslaving the port to the bridge
