f14b264f65 bus/vdev: replace device list lock by a recursive one
A device like failsafe can manage sub-devices.
When removing such device, it removes its sub-devices
and try to take the same vdev_device_list_lock.
It was causing a deadlock because the lock was not recursive.

Fixes: 35f462839b69 ("bus/vdev: add lock on device list")

The second part of the patch is solved by its own basic
block because it is inside a preprocessor conditional.

Bringing the declaration of the var to the top of the
function would require that also being given its own
preprocessor conditional, or a (void)var to avoid an
unused var warning.  The basic block is no worse than
those imho.

We want to do the arithmetic entirely in uint64_t
space, but with the +=, the rhs type becomes int since the
bitfields will fit in int.

Elaborate the artithmetic to be u64 = u64 + int + int, so
the type of the result is correct to be stored in the u64.

Also with this one, it is a cast that always occurred
and is just being done explicitly, with no changes to
the generated code.

The warning stack is misleading, it points to the last
element in the macro that produced the lhs of the subtraction
above.  But the only "unsigned long int" in the expression is
the result of the sizeof() on the rhs, it promotes the
subtraction result to unsigned long.  So the error actually
relates to the result of the outer subtraction.

The actual error is "you are trying to put an unsigned long
into a uint32_t".  We always did so, the fix is just to inform
the compiler it is intentional with an explicit cast.

               ^~

Again in this case we are making explicit the exact cast
that was always happening implicitly.  The patch does not
change the generated code.

The int32_t temp "x" is required to be signed to detect
a < 0 error condition from the lock status.  Afterwards,
it has always been implicitly cast to uint32_t when it
is used in the arguments to rte_atomic32_cmpset()...
gcc8.1 objects to the implicit cast now and requires us
to cast it explicitly.

fe613657ce app/testpmd: fix burst stats reporting
When RTE_TEST_PMD_RECORD_BURST_STATS is enabled, testpmd collects
burst statistics and includes them in the port stats report.  The
summary should include top 2 most frequent burst sizes, but there is a
bug in finding the top-2.  During the scan of burst size counts, the
top-2 can change only if top-1 also changes.

Added logic to update the top-2 if current burst size is larger than
existing top-2, but smaller than existing top-1.

"1 + value", where value is an uint16_t causes promotion

e9ff01b36d net/sfc: fix minimum number of Rx descriptors in ESSB mode
Number of descriptors in equal stride super-buffer Rx mode defines
number of packet buffers to be used. Each HW Rx descriptor has
many packet buffers and the number depends on total size of mbuf
and CONFIG_RTE_DRIVER_MEMPOOL_BUCKET_SIZE_KB value.
Typically it makes a bit less than 32 buffers per descriptor.
Since HW Rx descriptors must be pushed by 8, it makes about 256
as required minimum. Double it in advertised minimum to allow for
at least 2 refill blocks.

2ef1c0da89 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).

c16915b871 vhost: improve dirty pages logging performance
This patch caches all dirty pages logging until the used ring index
is updated.

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.
3. Less write memory barriers.
