Abstract: An Ethernet Physical layer (PHY) device includes a PHY interface and PHY circuitry. The PHY interface is configured to connect to a physical link. The PHY circuitry is configured to generate layer-1 frames that carry data for transmission to a peer Ethernet PHY device, to insert among the layer-1 frames one or more management frames that are separate from the layer-1 frames and that are configured to control a General-Purpose Input-Output (GPIO) port associated with the peer Ethernet PHY device, to transmit the layer-1 frames and the inserted management frames, via the PHY interface, to the peer Ethernet PHY device over the physical link, for controlling one or more operations of the GPIO port associated with the peer Ethernet PHY device, and to receive, via the PHY interface, one or more verifications acknowledging that the one or more management frames were received successfully at the peer Ethernet PHY device.

Abstract: A network device includes a memory, a memory access circuit, and a processor. The memory is configured to store a hash table for accessing a database of network addresses, the hash table including multiple buckets, each bucket dimensioned to store entries for up to a maximal permitted number of the network addresses. The memory access circuit is configured to receive a network address, to calculate a hash value over at least the network address by applying a hashing scheme selected from among a plurality of hashing schemes, to choose a bucket of the hash table based on the hash value, and to access information in the database pertaining to the network address by accessing the selected bucket. The processor is configured to select the hashing scheme to ensure that none of the buckets will be mapped to more than the maximal permitted number of the network addresses.

Abstract: In a method for establishing a communication link between a first network interface device and a second network interface device comprises, the second network interface device receives a training signal transmitted by the first network interface device. The training signal is for timing synchronization between the second network interface device and the first network interface device. The second network interface device determines, based on at least one physical characteristic of the training signal, a physical layer (PHY) parameter of the first network interface device. A controller of the second network interface device configures one or more components of the second network interface device to operate in a mode that corresponds to the determined PHY operating parameter of the first network interface device.

Abstract: A tire-condition ascertaining appliance for ascertaining a condition of a tire includes a housing defining an inner compartment that is substantially hollow. The housing is positioned within an inflation chamber defined between sidewalls of the tire and the rim. The appliance includes an electronics platform received within the inner compartment of the housing. The electronics platform ascertains a fluid condition of the tire and generates fluid-condition data, and processes the fluid-condition data. An antenna is connected to the electronics platform. The antenna receives the fluid-condition data indicative of the fluid condition and transmits the fluid-condition data to a remote location.
