Abstract
An embedded host channel adapter includes a transport layer module, a transport layer buffer, and a link layer module. The transport layer buffer is configured for storing transmit packet entries for virtual lanes serviced by the embedded host channel adapter. The link layer module is configured for supplying virtual lane priority information and virtual lane flow control information, for each virtual lane, to the transport layer module. The link layer module also configured for constructing transmit packets to be transmitted based on retrieval thereof from the transport layer buffer. The transport layer module is configured for selecting one of the virtual lanes for servicing based on the supplied virtual lane priority information and virtual lane flow control information for each of the virtual lanes, enabling the transport layer module to prioritize received work notifications, for generation of respective transmit packet entries.
