If the network devices connected to the system beyond
HSO_MAX_NET_DEVICES. add_net_device() in hso_create_net_device()
will be failed for the network_table is full. It will lead to
business failure which rely on network_table, for example,
hso_suspend() and hso_resume(). It will also lead to memory leak
because resource release process can not search the hso_device
object from network_table in hso_free_interface().

Add failure handler for add_net_device() in hso_create_net_device()
to solve the above problems.

Device removal can result in a large burst of driver warning messages
(20 - 30) sent to the kernel log. Most of these are register read/write
failures.

This change limits the rate at which these messages are emitted.

<title>lan78xx: Fix race condition in disconnect handling</title>

<content type='text'>
If there is a device disconnect at roughly the same time as a
deferred PHY link reset there is a race condition that can result
in a kernel lock up due to a null pointer dereference in the
driver's deferred work handling routine lan78xx_delayedwork().
The following changes fix this problem.

Add new status flag EVENT_DEV_DISCONNECT to indicate when the
device has been removed and use it to prevent operations, such as
register access, that will fail once the device is removed.

Stop processing of deferred work items when the driver's USB
disconnect handler is invoked.

Disconnect the PHY only after the network device has been
unregistered and all delayed work has been cancelled.

Disconnect the PHY only after the network device has been
unregistered and all delayed work has been cancelled.

If the interface is given an IP address while the device is
suspended (as a result of an auto-suspend event) there is a race
between lan78xx_resume() and lan78xx_open() that can result in an
exception or failure to handle incoming packets. The following
changes fix this problem.

Introduce a mutex to serialise operations in the network interface
open and stop entry points with respect to the USB driver suspend
and resume entry points.

Move Tx and Rx data path start/stop to lan78xx_start() and
lan78xx_stop() respectively and flush the packet FIFOs before
starting the Tx and Rx data paths. This prevents the MAC and FIFOs
getting out of step and delivery of malformed packets to the network
stack.

Stop processing of received packets before disconnecting the
PHY from the MAC to prevent a kernel exception caused by handling
packets after the PHY device has been removed.

Refactor device auto-suspend code to make it consistent with the
the system suspend code and make the suspend handler easier to read.

Add new code to stop wake-on-lan packets or PHY events resuming the
host or device from suspend if the device has not been opened
(typically after an IP address is assigned).

This patch is dependent on changes to lan78xx_suspend() and
lan78xx_resume() introduced in the previous patch of this patch set.
