A method of validation and host buffer allocation for unmapped fiber channel frames. More particularly, the invention encompasses a method of validating unmapped frames, each including a header and a payload, including receiving a frame as a current frame; determining if the current frame is a first frame in a sequence, and if so, saving the header and payload of the current frame in a buffer, and otherwise determining if the current frame is a next expected frame in the sequence; if the current frame is the next expected frame in the sequence, then saving the payload of the current frame in the buffer after the payload of the prior frame; determining if the current frame is a last frame in the sequence, and if so, sending a message to a host indicating receipt of the complete sequence; if the current frame is not the next expected frame in the sequence, then saving the header and payload of the current frame in the buffer, and sending a message to the host indicating receipt of a partial sequence. The host CPU is interrupted when either a complete sequence is received, or a partial sequence is received, followed by a frame from a different sequence. The host CPU may then process the concatenated payload of the sequence. The invention is particularly useful for processing TCP/IP frames in a Fiber Channel network.
