  • NCSI spec (DSP0222) defines several objects: package, channel, mode,
    filter, version and statistics etc. This introduces the data structs
    to represent those objects and implement functions to manage them.
    Also, this introduces CONFIG_NET_NCSI for the newly implemented NCSI
    stack.

    * The user (e.g. netdev driver) dereference NCSI device by
    "struct ncsi_dev", which is embedded to "struct ncsi_dev_priv".
    The later one is used by NCSI stack internally.
    * Every NCSI device can have multiple packages simultaneously, up
    to 8 packages. It's represented by "struct ncsi_package" and
    identified by 3-bits ID.
    * Every NCSI package can have multiple channels, up to 32. It's
    represented by "struct ncsi_channel" and identified by 5-bits ID.
    * Every NCSI channel has version, statistics, various modes and
    filters. They are represented by "struct ncsi_channel_version",
    "struct ncsi_channel_stats", "struct ncsi_channel_mode" and
    "struct ncsi_channel_filter" separately.
    * Apart from AEN (Asynchronous Event Notification), the NCSI stack
    works in terms of command and response. This introduces "struct
    ncsi_req" to represent a complete NCSI transaction made of NCSI
    request and response.
