Abstract
A channel adapter includes a link receive resource configured for initiating packet validation upon detecting a receive counter reaching a prescribed threshold corresponding to reception of an initial header of a data packet. Upon initiating packet validation, the link receive resource determines whether the initial header includes any errors. Any errors detected in the initial header are stored if the errors are detected prior to reception of an end of the data packet. Additional validation operations can be initiated upon reception of the respective headers. Upon receiving the end of the data packet, the link receive resource selectively reports the errors detected in the initial header based on whether any higher-priority error is detected relative to a prescribed error reporting order.
