gve: Add flow steering ethtool support

2024-06-26T00:48:33Z

Implement the ethtool commands that can be used to configure and query flow-steering rules. A large part of this change consists of translating the ethtool representation of 'ntuples' to our internal gve_flow_rule and vice-versa in the new created gve_flow_rule.c Considering the possible large amount of flow rules, the driver doesn't store all the rules locally. When the user runs 'ethtool -n ' to check the registered rules, the driver will send adminq command to query a limited amount of rules/rule ids(that filled in a 4096 bytes dma memory) at a time as a cache for the ethtool queries. The adminq query commands will be repeated for several times until the ethtool has queried all the needed rules.
