A plurality of media access controllers are time division multiplexed with one or more serializerdeserializer devices, wherein there are more MACs than SerDes devices andor a single multi-rate Ethernet MAC is able to communicate with a multi-rate PHY spanning speeds from 10 megabits per second to 10 gigabits per second using the same framing mechanism and structure. The chair comprises a base; first and second legs; a seat pivotally connected to the first and second legs; and a back pivotally connected to the seat. The antenna may comprise two separate stubs, each having an end portion positioned over a terminal of the chip module. Fasteners, such as screws, selectively secure side margin portions of the slide bed and ends of each reinforcement to each of the side rails. The combined hybrid queue derives storage efficiency benefits from linking unicast PDUs in linked lists and further derives benefits from a simple access to multicast PDU entries.
