- * per table and per each bucket.
- * 2. Key signature computation:
- * a. Pre-computed key signature: The key lookup operation is split between
- * two CPU cores. The first CPU core (typically the CPU core performing
- * packet RX) extracts the key from the input packet, computes the key
- * signature and saves both the key and the key signature in the packet
- * buffer as packet meta-data. The second CPU core reads both the key and
- * the key signature from the packet meta-data and performs the bucket
- * search step of the key lookup operation.
- * b. Key signature computed on lookup (do-sig): The same CPU core reads
- * the key from the packet meta-data, uses it to compute the key
- * signature and also performs the bucket search step of the key lookup
- * operation.
- * 3. Key size:
