bridge: add sysfs hook to flush forwarding table
The RSTP daemon needs to be able to flush all dynamic forwarding entries in the case of topology change. This is a temporary interface. It will change to a netlink interface before RSTP daemon is officially released. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org>
