Abstract
A device and a method for processing a frame, the method includes: receiving a frame; retrieving a lookup key parse command that includes an instruction field and an bitmap representative of selected frame fields to be searched in the frame; generating a lookup key by extracting at least one frame field if the type of the received frame matches an expected frame type; and looking up, using the lookup key, for additional frame processing instructions.
