ice: Initialize Flow Director resources
Flow Director allows for redirection based on ntuple rules. Rules are programmed using the ethtool set-ntuple interface. Supported actions are redirect to queue and drop. Setup the initial framework to process Flow Director filters. Create and allocate resources to manage and program filters to the hardware. Filters are processed via a sideband interface; a control VSI is created to manage communication and process requests through the sideband. Upon allocation of resources, update the hardware tables to accept perfect filters.
