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).
