Subject: [PATCH RFC v1 0/7] NCSI Support

This patchset is prototype requesting for comments.

This series of patches intends to support NCSI stack, which is specified by
DSP0222. One NCSI enabled interface potentially connects to multiple packages
and channels, but there is one active channel at once when hardware arbitration
is disabled. No hardware arbitration isn't supported by this patchset:

   * NIC driver registers NCSI device when the network device is registered. The
     NCSI device should be started when bringing up the interface so that the
     active channel can be choosed from the available channels and starts to provide
     service.
   * When NCSI AEN packet is received from currently active channel for sake of
     failure, another active channel is tried to choosed to accomplish the failover.
   * Reserved netlink interface for NCSI is supported so that userland can retrieve
     NCSI information or configure from/to NCSI channels.
   * The first user of NCSI stack is faraday driver (ftgmac100.c).
