    enic: Add Accelerated RFS support · a145df23

    This patch adds supports for Accelerated Receive Flow Steering.
    
    When the desired rx is different from current rq, for a flow, kernel calls the
    driver function enic_rx_flow_steer(). enic_rx_flow_steer adds a IP-TCP/UDP
    hardware filter.
    
    Driver registers a timer function enic_flow_may_expire. This function is called
    every HZ/4 seconds. In this function we check if the added filter has expired
    by calling rps_may_expire_flow(). If the flow has expired, it removes the hw
    filter.
    
    As of now adaptor supports only IPv4 - TCP/UDP filters.
