Method and system for processing layered networking protocol packets

An adapter for processing a payload data and destination information for the payload data received over an interconnect, the payload data arranged in one or more predetermined interconnect format, the adapter comprising:

• a send filter bank configured to process a portion of the payload data and assemble the payload data with the destination information in a predetermined layered protocol format from among a plurality of protocol formats;
• wherein the destination information is included with or embedded in a direct memory access (DMA) request for transferring the payload data through the adapter;
• wherein the send filter bank includes a plurality of send filter logic, where each send filter logic includes:
• an output filter control logic that (i) generates a first control signal for manipulating the payload data and the destination information by performing one or more of (a) inserting a bit, (b) removing a bit, and (c) rearranging bits;
• (ii) generates a second control signal for generating a code that is sent with the payload and the destination information;
• and (iii) generates a third control signal for appending header information stored at a storage location to the payload data;
• an insert field logic that generates information that is inserted or sent with the payload based on the first control signal;
• and
• an error detection and correction code generator that generates the code in response to the second control signal;
• wherein when the payload for a data transfer is split into multiple packets then the header information stored at the storage location is updated before being sent with the multiple packets.

A method of processing an information packet of a layered information transfer protocol received over a link, the information packet arranged in one or more predetermined layered protocol format and including a header portion and a payload data, the method comprising:

• processing a portion of the information packet through a receive filter bank, wherein the receive filter bank includes a plurality of receive filter logic, each receive filter logic includes an input filter control logic that (i) uses a decoded header portion of the information packet to generate a first control signal for manipulating the information packet by performing one or more of (a) inserting a bit, (b) removing a bit, and (c) rearranging bits in the information packet based;
• (ii) generates a second control signal that is sent to a validation logic for generating a validation code for verifying error detecting code included in the information packet;
• and (iii) generates a third control signal for transferring post processed information from a storage location of the receive filter logic to a next location;
• setting up the plurality of receive filter logic based on the decoded header portion, wherein each of the input filter control logic sets up the corresponding receive filter logic;
• and
• assembling the payload data in a predetermined interconnect format from among a plurality of interconnect formats;
• wherein information packet processing is split among the plurality of receive filter logic such that an output from one receive filter logic is input to another receive filter logic until the processing is complete.
