net/tap: fix isolation mode toggling
Running testpmd command "flow isolae <port> 0" (i.e. disabling flow
isolation) followed by command "flow isolate <port> 1" (i.e. enabling
flow isolation) may result in a TAP error:
PMD: Kernel refused TC filter rule creation (17): File exists
Root cause analysis: when disabling flow isolation we keep the local
rule to redirect packets on TX (TAP_REMOTE_TX index) while we add it
again when enabling flow isolation. As a result this rule is added
two times in a row which results in "File exists" error.
The fix is to identify the "File exists" error and silently ignore it.
Another issue occurs when enabling isolation mode several times in a
row in which case the same tc rules are added consecutively and
rte_flow structs are added to a linked list before removing the
previous rte_flow structs.
The fix is to act upon isolation mode command only when there is a
change from "0" to "1" (or vice versa).

This patch caches all dirty pages logging until the used ring index

The goal of this optimization is to fix a performance regression
introduced when the vhost library started to use atomic operations
to set bits in the shared dirty log map. While the fix was valid
as previous implementation wasn't safe against concurrent accesses,
contention was induced.
With this patch, during migration, we have:
1. Less atomic operations as only a single atomic OR operation
per 32 or 64 (depending on CPU) pages.
2. Less atomic operations as during a burst, the same page will
be marked dirty only once.

mempool: fix virtual address population
Currently, populate_virt will check if mempool is already populated.
This will cause inability to reserve multi-chunk mempools if
contiguous memory is not a hard requirement, because if allocating
all-contiguous memory fails, mempool will retry with virtual addresses
and will call populate_virt. It seems that the original code never
anticipated more than one non-physically contiguous area.
Fix it by removing the check in populate virt. populate_anon() function
calls populate_virt() also, and it can be reasonably inferred that it is
expecting that virtual area is not already populated. Even though a
similar check is already in place there, also add the check that was
part of populate_virt() just in case.

DPDK-specific runtime directory, under which all runtime data
will be placed. The template for creating this runtime directory
is the following:
<base path>/dpdk/<DPDK prefix>/
Where <base path> is set to either "/var/run" if run as root, or
$XDG_RUNTIME_DIR if run as non-root, with a fallback to /tmp if
$XDG_RUNTIME_DIR is not defined. So, for example, if run as root,
by default all runtime data will be stored at /var/run/dpdk/rte/.

bus/dpaa: fix inconsistent struct alignment
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.

by the host thread when the slave link status is changed.
In addition, the bonding PMD uses the callback for slave activation

Consequently, a slave may be activated in the same time by two
different threads and may cause a lot of optional errors, for example,

net/mlx5: fix inlining segmented TSO packet
When a multi-segmented packet is inlined, data can be further inlined even
after the first segment. In case of TSO packet, extra inline data after TSO
header should be carried by an inline DSEG which has 4B inline header
recording the length of the inline data. If more than one segment is
inlined, the length doesn't count from the second segment. This will cause
a fault in HW and CQE will have an error, which is ignored by PMD.

There is time between the sub-device port probing by the sub-device PMD

example, the port will be exposed to the applications which use

Thus, ownership unaware applications may manage the port in this time
