This patch modifies the MIC host and card drivers to start using the
VOP driver. The MIC host and card drivers now implement the VOP bus
operations and register a VOP device on the VOP bus. MIC driver stack
documentation is also updated to include the new VOP driver.Reviewed-by: Ashutosh Dixit

This patch updates the MIC host daemon to work with corresponding
changes in COSM. Other MIC daemon fixes, cleanups and enhancements as
are also rolled into this patch. Changes to MIC sysfs ABI which go
into effect with this patch are also documented.Reviewed-by: Sudeep Dutt

This patch enables support for OSPM suspend and resume in the MIC
driver. During a host suspend event, the driver performs an
orderly shutdown of the cards if they are online. Upon resume, any
cards that were previously online before suspend are rebooted.
The driver performs an orderly shutdown of the card primarily to
ensure that applications in the card are terminated and mounted
devices are safely un-mounted before the card is powered down in
the event of an OSPM suspend.The driver makes use of the MIC daemon to accomplish OSPM suspend
and resume. The driver registers a PM notifier per MIC device.
The devices get notified synchronously during PM_SUSPEND_PREPARE and
PM_POST_SUSPEND phases.During the PM_SUSPEND_PREPARE phase, the driver performs one of the
following three tasks.
1) If the card is 'offline', the driver sets the card to a
'suspended' state and returns.
2) If the card is 'online', the driver initiates card shutdown by
setting the card state to suspending. This notifies the MIC
daemon which invokes shutdown and sets card state to 'suspended'.
The driver returns after the shutdown is complete.
3) If the card is already being shutdown, possibly by a host user
space application, the driver sets the card state to 'suspended'
and returns after the shutdown is complete.During the PM_POST_SUSPEND phase, the driver simply notifies the
daemon and returns. The daemon boots those cards that were previously
online during the suspend phase.Signed-off-by: Ashutosh Dixit

This patch introduces a sample user space daemon which
implements the virtio device backends on the host. The daemon
creates/removes/configures virtio device backends by communicating with
the Intel MIC Host Driver. The virtio devices currently supported are
virtio net, virtio console and virtio block. Virtio net supports TSO/GSO.
The daemon also monitors card shutdown status and takes appropriate actions
like killing the virtio backends and resetting the card upon card shutdown
and crashes.Co-author: Ashutosh Dixit
