Since all other apps have been moved to the "app" folder, the autotest app
remains alone in the test folder. Rather than having an entire top-level
folder for this, we can move it back to where it all started in early
versions of DPDK - the "app/" folder.
This move has a couple of advantages:
* This reduces clutter at the top level of the project, due to one less
folder.
* It eliminates the separate build task necessary for building the
autotests using make "make test-build" which means that developers are
less likely to miss something in their own compilation tests
* It re-aligns the final location of the test binary in the app folder when
building with make with it's location in the source tree.
For meson builds, the autotest app is different from the other apps in that
it needs a series of different test cases defined for it for use by "meson
test". Therefore, it does not get built as part of the main loop in the
app folder, but gets built separately at the end.

Fix crash in pmd_perf_test autotest (div by 0) when no packets received
Also fixes the fact that the test passes even if exec_burst fails
To repeat the issue:
The system must be incorrectly set up so that all packets will be lost,
i.e. no loopback cable, etc. This is an edge case, but still the test
should not crash or pass when failing.

One of the ways to reproduce the issue:
testpmd <EAL-OPTIONS> -- -i --txqflags=0
testpmd> set fwd txonly
testpmd> set txpkts 64,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4
testpmd> set txsplit rand
testpmd> start
After some time TX on ixgbe queue will hang,
and all packet transmission on that queue will stop.
This bug was first reported and investigated by
Vlad Zolotarov <vladz@cloudius-systems.com>:
"We can reproduce this issue when stressed the xmit path with a lot of highly
fragmented TCP frames (packets with up to 33 fragments with non-headers
fragments as small as 4 bytes) with all offload features enabled."
The root cause is that ixgbe_xmit_pkts() in some cases violates the HW rule
that the distance between TDs with RS bit set should not exceed 40 TDs.
>From the latest 82599 spec update:
"When WTHRESH is set to zero, the software device driver should set the RS bit
in the Tx descriptors with the EOP bit set and at least once in the 40
descriptors."
The fix is to make sure that the distance between TDs with RS bit set
would never exceed HW limit.
As part of that fix, tx_rs_thresh for ixgbe PMD is not allowed to be greater
then to 32 to comply with HW restrictions.
With that fix slight slowdown for the full-featured ixgbe TX path
might be observed (from our testing - up to 4%).
ixgbe simple TX path is unaffected by that patch.

Latest mbuf changes (priv_size addition and related fixes)
exposed small problem with testpmd and few other sample apps:
when mbuf size is exaclty 2KB or less, that causes
ixgbe PMD to select scattered RX even for configs with 'normal'
max packet length (max_rx_pkt_len == ETHER_MAX_LEN).
To overcome that problem and unify the code, new macro was created
to represent recommended minimal buffer length for mbuf.
When appropriate, samples are updated to use that macro.

The Link bonding library is incorrectly using receive packet type flags
in the transmit policy hashing functions, which would cause packets
generated locally to be incorrectly distributed across the slave
devices. This patch completely removes the dependency on the packet
type flags and uses the ether_type from either the Ethernet header or
the VLAN headers for branching.
This patch also includes the associate changes in the test suite and in
the packet_burst_generator code to remove the dependences on the packet
type flags.

[Thomas: updated on HEAD, including PPC]
The unit test can be used to measure cycles per packet in different rx/tx routines.
The NIC works in loopback mode. So it doesn't require test equipment to measure throughput.
As result, the unit test shows the average cycles per packet consuming.
When doing the test, make sure the link is UP.
Usage Example:
1. Run unit test app in interactive mode
app/test -c f -n 4 -- -i
2. Run and wait for the result
pmd_perf_autotest
There's option to choose rx/tx pair, default is vector.
set_rxtx_mode [vector|scalar|full|hybrid]
Note: To get acurate scalar fast, please choose 'vector' or 'hybrid' without INC_VEC=y in config
It supports to measure standalone rx or tx.
Usage Example:
Choose rx or tx standalone, default is both
set_rxtx_anchor [rxtx|rxonly|txonly]
It also supports to measure standalone RX burst cycles.
In this way, it won't repeat re-send received packets.
Now it measures two situations, poll before/after xmit(w or w/o desc. cache conflict)
Usage Example:
Set stream control mode, by default is continuous
set_rxtx_sc [continuous|poll_before_xmit|poll_after_xmit]
