app/testpmd: fix Tx scheduling interval

The first "set txtimes" command parameter specifies the time
interval between scheduled send bursts for single queue. This
interval should be the same for all the forwarding ports.
It requires to maintain the timing related variables on per
queue basis instead of per core, as currently implemented.
This resulted in wrong burst intervals if two or more cores
were generating the scheduled traffic for two or more ports
in txonly mode.

This patch moves the timing variable to the fstream structure.
Only txonly forwarding mode with enabled send scheduling is
affected.

app/testpmd: fix txonly forwarding

When random number of Tx segments is enabled, because the actual
number of segments may be only one, the first segment of the Tx
packets must accommodate a complete being sending Eth/IP/UDP packet.

Besides, if multiple flow is enabled, the forwarding will update
the IP and UDP header, these headers shouldn't cross segments.
This also requires the first Tx segment can accommodate a complete
Eth/IP/UDP packet.

In addition, if time stamp is enabled, the forwarding needs more
Tx segment space for time stamp information.

This patch adds checks in beginning of forward engine to make sure
all above conditions are met.

app/testpmd: update forward engine beginning

For each forward engine, there may be some special conditions
must be met before the forwarding runs.

Adding checks for these conditions in configuring is not suitable,
because one condition may rely on multiple configurations, and the
conditions required by each forward engine is not general.

The best solution is each forward engine has a callback to check
whether these conditions are met, and then testpmd can call the
callback to determine whether the forwarding can be started.

There was a void callback 'port_fwd_begin' in forward engine,
it did some initialization for forwarding, this patch updates its
return value then we can add some checks in it to confirm whether
the forwarding can be started. In addition, this patch calls the
callback before the forwarding stats is reset and then launches the
forwarding engine.

app/testpmd: fix packet header in txonly mode

In txonly forward mode, the packet header is fixed by the initial
setting, including the packet length and checksum. So when the packets
varies, this may cause a packet header error. Currently, there are two
methods in txonly mode to randomly change the packets.
1. Set txsplit random and txpkts (x[,y]*), the number of segments
each packets will be a random value between 1 and total number of
segments determined by txpkts settings.
The step as follows:
a) ./testpmd -w xxx -l xx -n 4 -- -i --disable-device-start
b) port config 0 tx_offload multi_segs on
c) set fwd txonly
d) set txsplit rand
e) set txpkts 2048,2048,2048,2048
f) start
The nb_segs of the packets sent by testpmd will be 1~4. The real packet
length will be 2048, 4096, 6144 and 8192. But in fact the packet length
in ip header and udp header will be fixed by 8178 and 8158.

2. Set txonly-multi-flow. the ip address will be varied to generate
multiple flow.
The step as follows:
a) ./testpmd -w xxx -l xx -n 4 -- -i --txonly-multi-flow
b) set fwd txonly
c) start
The ip address of each pkts will change randomly, but since the header
is fixed, the checksum may be a error value.

Therefore, this patch adds a function to update the packet length and
check sum in the pkts header when the txsplit mode is set to rand or
multi-flow is set.

The testpmd application forwards data in multiple threads.
In the txonly mode the Tx timestamps must be initialized
on per thread basis to provide phase shift for the packet
burst being sent. This per thread initialization was performed
on zero value of the variable in thread local storage and
happened only once after testpmd forwarding start. Executing
"start" and "stop" commands did not cause thread local variables
zeroing and wrong timestamp values were used.

app/testpmd: add Tx scheduling command

This commit adds testpmd capability to provide timestamps on the packets
being sent in the txonly mode. This includes:

- SEND_ON_TIMESTAMP support
new device Tx offload capability support added, example:

testpmd> port config 0 tx_offload send_on_timestamp on

- set txtimes, registers field and flag, example:

testpmd> set txtimes 1000000,0

This command enables the packet send scheduling on timestamps if
the first parameter is not zero, generic format:

testpmd> set txtimes (inter),(intra)

where:

inter - is the delay between the bursts in the device clock units.
If "intra" (next parameter) is zero, this is the time between the
beginnings of the first packets in the neighbour bursts, if "intra"
is not zero, "inter" specifies the time between the beginning of
the first packet of the current burst and the beginning of the last
packet of the previous burst. If "inter"parameter is zero the send
scheduling on timestamps is disabled (default).

intra - is the delay between the packets within the burst specified
in the device clock units. The number of packets in the burst is
defined by regular burst setting. If "intra" parameter is zero no
timestamps provided in the packets excepting the first one in the
burst.

As the result the bursts of packet will be transmitted with
specific delay between the packets within the burst and specific
delay between the bursts. The rte_eth_read_clock() is supposed to
be engaged to get the current device clock value and provide the
reference for the timestamps. If there is no supported
rte_eth_read_clock() there will be no provided send scheduling on
the device.

app/testpmd: add mempool with external data buffers

The new mbuf pool type is added to testpmd. To engage the

The objective of this patch is just to test whether mbuf pool
with externally attached data buffers works OK. The memory for
data buffers is allocated from DPDK memory, so this is not
"true" external memory from some physical device (this is
supposed the most common use case for such kind of mbuf pool).

The user should be aware that not all drivers support the mbuf
with EXT_ATTACHED_BUF flags set in newly allocated mbuf (many
PMDs just overwrite ol_flags field and flag value is getting
lost).
