Abstract
One or more bits of the destination MAC address indicate a number of times a reset event has occurred. These bits may be referred to as a generation number. The generation number in a destination MAC address is updated when a reset event occurs. In this way, frames issued by the sender prior to the reset may be distinguished from frames issued after the reset, since the destination MAC addresses in those frames will not match. In this way, the recipient device is protected from stale packets.
