25.10.2 Receive Frame Processing with Pattern Matching
The frame processing with pattern matching includes receive frame filing. The Ethernet
controller provides the following powerful features in processing a receive frame:
Up to eight exact unicast or multicast MAC address matches
IP address filtering
Frame filing based on pattern hits
Frame rejection or acceptance based on pattern hits
Pattern detection within the first 256 bytes of a frame
Up to 16 unique 4-byte patterns
Flexible programmable pattern size from four to 64 bytes
Programmable match start offset (0 to 252 bytes within the frame depending on pattern
size)
Noncontiguous, concatenated patterns (each bit of a pattern can be individually masked)
Multi-pattern hit detection
Pattern matching enables you to process receive frames with a set of tools to assist network
applications. Features such as filing of frames in queues based on a pattern hit can accelerate post
processing of data. You can further enhance address recognition filtering by applying additional
processing to frames that pass the destination address check. Flexibility is built into the Ethernet
controller pattern matching to give you more control in manipulating receive frames. Table 25-9
shows an example of how to use the Ethernet controller frame processing features for specific
applications.
