A fly-by checksum is generated at a lower layer of the protocol stack and travels up to a high layer of a protocol stack to verify incoming data. In one embodiment, a network adapter comprises includes one or more protocol stacks and a LAN controller that includes a fly-by checksum generation unit. A checksum algorithm is registered with the fly-by checksum generation unit for each protocol layer that is to receive a fly-by checksum. As an incoming packet is transferred from network media to network adapter memory, the fly-by checksum generation unit calculates a fly-by checksum for each checksum algorithm that has been registered. After the fly-by checksums are complete, they are transmitted to the network adapter memory and are transmitted up the appropriate protocol stack within a checksum channel. When data reaches a layer of the protocol stack for which the fly-by checksum was generated, the fly-by checksum is removed from the checksum channel and is used to verify the integrity of the data.

A network node includes a serial physical sublayer (PHY) chip, a parallel PHY chip, and a media access control (MAC) chip. The serial physical sublayer chip, includes a single bit transmit data input, a single bit receive data output, and serial PHY control signal input/output (I/O) lines. The parallel PHY chip includes a multi-bit transmit data input, a multi-bit receive data output, and parallel PHY control signal I/O lines. The MAC chip includes a multi-bit transmit data output, a multi-bit receive data input and parallel control signal I/O lines. The multi-bit transmit data output is connected to the multi-bit transmit data input. One bit of the multi-bit transmit data output is connected to the single bit transmit data input. The multi-bit receive data input is connected to the multi-bit receive data output. One bit of the multi-bit receive data input is connected to the single bit receive data output.

Methods and apparatus are provided that facilitate debugging operations for components that may include different power domains. In an embodiment, an integrated circuit (IC) includes a plurality of hardware sectors, each hardware sector associated with a debug observability circuit that is served by a debug data bus of a debug circuit. The plurality of hardware sectors includes a controlled sector residing in a dynamically-controlled power domain that may be turned off while the power domain of another sector remains on. A selectively switchable data bus component is configured to couple the debug observability circuit associated with the controlled sector to the debug data bus when the power to the controlled sector is on and to switch to bypass the debug observability circuit associated with the controlled sector when the power to the controlled sector is not on.
