When a removable device is plugged-out, a RMV interrupt is invoked and
the application can catch the event in order to stop the device
management.
The Testpmd wrong behavior in this case is to detach the removed device
using the EAL detach API.
The EAL API does not invalidate the ethdev port and the port keeps
appearing as valid from the ethdev point of view.
Thus, the next operations for the ethtev port X may trigger an invalid
rte_device access. For example, calling "show port info X" may cause
segfault.
Moreover, the removed port is not removed from the Testpmd data-path
structures. Therefore, the invalid device may still be used by the
Testpmd data-path.
Call the Testpmd detach_port() function which uses the ethdev detach
API, and prepare the Testpmd forward ports database for a new
forwarding session without the detached port.

In the RMV device event callback, there is a call for the removed
device stop operation which triggers a link status operation for the
removed device.
It may casue an error from the removed device PMD.
Skip the link status operation in the above described case.

When the user uses the synchronic hot-plug commands, attach\detach, in
order to insert\remove a port from the system, the forward ports list
update is missed in the current implementation.
Thus, an invalid port may be used for data-path in case of detach
because the detached port was not removed from the forward port list.
In addition, a new port is not used for data-path in case of attach, as the
default behavior of Testpmd, because the attached port was not inserted
to the forward port list.
Update the forward port list in the above cases to allow the correct
port usage for data-path in the next packet forwarding start.

A port Rx queue flush is done when the packet forwarding starts in
order to clean the port statistics for a new traffic session.
The flush operation is wrongly called before the update of the new
forward ports, and may fail due to flush operation for an invalid port
configured by the old session.
Move the new forward port setup to be done before the Rx queue flush.

When the forward ports are changed either by new portlist\portmask
configurations or by a port detachment, all the old forward streams
are freed and new streams are allocated to be aligned with the new
forward ports.
If the number of the forward ports drops to 0, there is an attempt
to wrongly allocate 0 memory for the streams.
Skip the streams memory allocation if no forward ports are configured.

There are several cases of an invalid port data access that causes the

Wrongly, the port with id 0 is printed in all the above described

Testpmd allows to create and control bonding devices by run time
command lines using the bonding PMD API.
Some bonding device slaves operations (close, stop, etc) should not be
used by the application and must be managed by the bonding PMD.
Thus, Testpmd manages slave flags to prevent the special operations
calls and when a slave is added to bonding device by a run time command
line, the flag is set.
There is one more way to define the slaves for a bonding device using
EAL command line and Testpmd doesn't set the slave flag in this case
what causes to the special operations to be called by Testpmd.
Add one more check to detect bonding slave device.

By the way, alloc_q can be processed together to speed up the
