A pattern template creation shares the parsing mechanism with
a simple flow creation. The pattern template creation only consists
of pattern items while the flow creation continues with actions.
The parsing mechanism now accommodates both cases and allows to stop
at the item end token, which should not happen for the flow creation.
Fix parsing mechanism to differentiate between these two cases.

Ops population functions are called in datapath. Keeping it common for
PDCP & DOCSIS would mean ops population would have additional
conditional checks causing the throughput reported to be lower than what
the PMD is capable of.
Separate out routine for IPsec cases and split vector population and op
preparation into two loops to allow 2 rte_rdtsc_precise() calls to
capture cycles consumed for memcpying the vector. Checking the cycle
count from the loop would mean more calls to the same API.

The structure "rte_flow_item_geneve_opt" is not a protocol header of

which points to the actual variable-length option data. So the

There is 4 bytes hole before the pointer in a 64-bit system. The
option header is just 4 bytes. When using offsetof() to get the
fixed part's size of option header, the wrong value 8 was got. When

The csum FWD mode parses any received packet to set mbuf offloads for
the transmitting burst, mainly in the checksum/TSO areas.
In the case of a tunnel header, the csum FWD tries to detect known
tunnels by the standard definition using the header's data and fallback
to check the packet type in the mbuf to see if the Rx port driver
already sign the packet as a tunnel.
In the fallback case, the csum assumes the tunnel is VXLAN and parses
the tunnel as VXLAN.
When the GENEVE tunnel was added to the known tunnels in csum, its
parsing trial was wrongly located after the pkt type detection, causing
the csum to parse the GENEVE header as VXLAN when the Rx port set the
tunnel packet type.
Remove the fall back case to VXLAN.
Log error of unrecognized tunnel if no tunnel was parsed successfully.

In gpudev communication list this is useful to store the

A communication list status flag allocated on GPU memory
and mapped for CPU visibility can be updated by CPU and polled
by a GPU workload.
The polling operation is more frequent than the CPU update operation.
Having the status flag in GPU memory reduces the GPU workload polling

Add gre_option command for matching optional fields
(checksum/key/sequence) in GRE header. The item must follow gre item,
and the item does not change the flags in gre item, the application
should set the flags in gre item correspondingly.
Application can still use gre_key item 'gre_key value is xx' for key
matching, the effect is the same with using 'gre_option key is xx'.
The examples for gre_option are as follows:
To match on checksum field with value 0x11:
testpmd> ... pattern / eth / gre c_bit is 1 / gre_option checksum is
0x11 / end ..
To match on checksum field with value 0x11 and any value of key:
testpmd> ... pattern / eth / gre c_bit is 1 k_bit is 1 / gre_option
checksum is 0x11 / end ..
To match on checksum field with value 0x11 and no key field in packet:
testpmd> ... pattern / eth / gre c_bit is 1 k_bit is 0 / gre_option
checksum is 0x11 / end ..
The invalid patterns for gre_option are as follows:
testpmd> ... pattern / eth / gre / gre_option checksum is 0x11 / end ..
(c_bit in gre item not present)

Segmentation fault
The reason to the bug is that rte timer do not be cancelled when quit.
That is, in 'bond_ethdev_start', resources are allocated according to
different bonding mode. In 'bond_ethdev_stop', resources are free by
the corresponding mode.
For example, 'bond_ethdev_start' start bond_mode_8023ad_ext_periodic_cb
timer for bonding mode 4. and 'bond_ethdev_stop' cancel the timer only
when the current bonding mode is 4. If the bonding mode is changed,
and directly quit the process, the timer will still on, and freed memory
will be accessed, then segmentation fault.
'bonding mode' changed means resources changed, reallocate resources for
different mode should be done, that is, device should be restarted.

Memory allocator performance is crucial to applications that deal
with large amount of memory or allocate frequently. DPDK allocator
performance is affected by EAL options, API used and, at least,
allocation size. New autotest is intended to be run with different
EAL options. It measures performance with a range of sizes
for dirrerent APIs: rte_malloc, rte_zmalloc, and rte_memzone_reserve.
Work distribution between allocation and deallocation depends on EAL
options. The test prints both times and total time to ease comparison.
Memory can be filled with zeroes at different points of allocation path,
but it always takes considerable fraction of overall timing. This is why
the test measures filling speed and prints how long clearing takes
for each size as a reference (for rte_memzone_reserve estimations
are printed).
