Stateless Fibre Channel Sequence Acceleration for Fibre Channel Traffic Over Ethernet

A method for offloading Fibre Channel transmit data in an I/O operation, the transmit data comprising a plurality of Fibre Channel sequences, each of the plurality of Fibre Channel sequences comprising of a plurality of frames, the method comprising:

• generating a single transmit sequence request descriptor for transmitting all of the plurality of frames;
• creating an Ethernet header for each of the plurality of frames in response to information in the transmit sequence request descriptor;
• creating a FCoE encapsulation header for each of the plurality of frames in response to information in the transmit sequence request descriptor;
• creating a Fibre Channel header for each of the plurality of frames in response to information in the transmit sequence request descriptor;
• creating start of frame and end of frame delimiters in response to information in the transmit sequence request descriptor;
• inserting data into each of the plurality of frames;
• computing Fibre Channel CRC and Ethernet FCS for each of the plurality of frames;
• and
• transmitting the plurality of frames over a network,
• wherein, in each of the plurality of frames, the Ethernet header precedes the FCoE encapsulation header, which precedes the Fibre Channel header, which precedes the data;
• and
• wherein, in each of the plurality of frames, the data is followed by the Fibre Channel CRC, which is followed by the Ethernet FCS.
