The actual descriptor for qm_mr_entry is 64-byte aligned.
But the original code plays a trick, and puts a u8 common
to the three descriptor subtypes in the union afterwards
outside their structure definitions.
Unfortunately since they compose a struct qm_fd with
alignment 8, this trick destroys the ability of the compiler
to understand what has happened, resulting in this kind of
problem:
drivers/bus/dpaa/include/fsl_qman.h:354:3: error:
alignment 1 of ‘struct <anonymous>’ is less than 8 [-Werror=packed-not-aligned]
} __packed dcern;
on gcc 8 / Fedora 28 out of the box.
This patch moves the u8 verb into the structure definitions
composed into the union, so the alignment of the parent struct
containing the alignment 8 object can also be seen to be
alignment 8 by the compiler. Uses of .verb are fixed up to use
.ern.verb (the same offset of +0 inside all the structs in
the union).
The final struct layout should be unchanged.

The bonding PMD decides to activate\deactivate its slaves according to
the slaves link statuses.
Thus, it registers to the LSC events of the slaves ports and
activates\deactivates them from its LSC callbacks called asynchronously
by the host thread when the slave link status is changed.
In addition, the bonding PMD uses the callback for slave activation
when it tries to start it, this operation is probably called by the
master thread.
Consequently, a slave may be activated in the same time by two
different threads and may cause a lot of optional errors, for example,
slave mempool recreation with the same name causes an error.
Synchronize the critical section in the LSC callback using a special
new spinlock.

This can happen if only the first port is started up and the check
to free up all resources is still satisfied. When dev_close is

up by the first port.
Thus, by moving to dev_uninit() all the ports can be teared down

When an ethdev port is released, a destroy event is triggered to notify
the users about the released port.
A bit before the destroy event is triggered, the port becomes invalid
by changing its state to UNUSED and cleaning its data. Therefore, the
port is invalid for the destroy event callback process and the users
may get a wrong information of the port.
Move the destroy event emitting to be called before the port
invalidation.

In this time, the port is available for the application usage. For
example, the port will be exposed to the applications which use
RTE_ETH_FOREACH_DEV iterator.
Thus, ownership unaware applications may manage the port in this time
what may cause a lot of problematic behaviors in the fail-safe
