The Management Complex (MC) firmware initially allowed the configuration of a single key to be used both for Rx flow hashing and flow classification. This prevented us from supporting Rx flow classification independently of the hash key configuration.
Newer firmware versions expose separate commands for configuring the two types of keys, so we can use them to introduce Rx classification support. For frames that don't match any classification rule, we fall back to statistical distribution based on the current hash key. The first patch in this set updates the Rx hashing code to use the new firmware API for key config. Subsequent patches introduce the firmware API for configuring the classification and actual support for adding and deleting rules via ethtool.
