When we have multiple devices attempting to sync the same address to a single destination, each device should be permitted to sync it once. To accomplish this, pass the 'sync_cnt' of the source address when adding the addresss to the lower device. 'sync_cnt' tracks how many time a given address has been succefully synced. This way, we know that if the 'sync_cnt' passed in is 0, we should sync this address. Also, turn 'synced' member back into the counter as was originally done in commit 4543fbef. net: count hw_addr syncs so that unsync works properly. It tracks how many time a given address has been added via a 'sync' operation. For every successfull 'sync' the counter is incremented, and for ever 'unsync', the counter is decremented. This makes sure that the address will be properly removed from the the lower device when all the upper devices have removed it. Reported-by:
