net: enetc: add support for "Add" and "Delete" operations to IPFT

Browse source 
The ingress port filter table (IPFT )contains a set of filters each
capable of classifying incoming traffic using a mix of L2, L3, and L4
parsed and arbitrary field data. As a result of a filter match, several
actions can be specified such as on whether to deny or allow a frame,
overriding internal QoS attributes associated with the frame and setting
parameters for the subsequent frame processing functions, such as stream
identification, policing, ingress mirroring. Each entry corresponds to a
filter. The ingress port filter entries are added using a precedence
value. If a frame matches multiple entries, the entry with the higher
precedence is used. Currently, this patch only adds "Add" and "Delete"
operations to the ingress port filter table. These two interfaces will
be used by both ENETC driver and NETC switch driver.
