摘要： A method for offloading Fiber Channel transmit data in an I/O operation. The transmit data includes Fiber Channel sequences, each Fiber Channel sequence includes multiple frames. The method includes generating a single transmit sequence request descriptor for transmitting all of the plurality of frames; creating an Ethernet header, a FCoE encapsulation header, and a Fiber Channel header for each frame in response to information in the transmit sequence request descriptor; creating start of frame and end of frame delimiters; inserting data into each frame; computing Fiber Channel CRC and Ethernet FCS for each frame; and transmitting the plurality of frames over a network. In each of the plurality of frames, the Ethernet header precedes the FCoE encapsulation header, which precedes the Fiber Channel header, which precedes the data. The data is followed by the Fiber Channel CRC, which is followed by the Ethernet FCS.
