From: Hemant Agrawal <[email protected]> The default size for a QoS key is 24 bytes. If the key size is smaller than the maximum, use the default (minimum) key size instead of always returning the maximum size (56 bytes). This allows smaller flow tables to be used when the extracted key fits within the default size.
