9ebefc080b app/testpmd: fix RSS flags size
Since commit 8a387fa85f02 ("ethdev: more RSS flags") in DPDK 1.7,
RSS flags have increased.
According to rss_hf definition in rte_eth_rss_conf, it shall be uint64 type.
Using uint16 will get truncated value, and cause incorrect output. This
fix corrected this issue.

2437814390 app/testpmd: add a verbose mode to checksum forward engine
If the user specifies 'set verbose 1' in testpmd command line,
the csum forward engine will dump some informations about received
and transmitted packets, especially which flags are set and what
values are assigned to l2_len, l3_len, l4_len and tso_segsz.

This can help someone implementing TSO or hardware checksum offload to
understand how to configure the mbufs.

Example of output for one packet:

 --------------
 rx: l2_len=14 ethertype=800 l3_len=20 l4_proto=6 l4_len=20
 tx: m->l2_len=14 m->l3_len=20 m->l4_len=20
 tx: m->tso_segsz=800
 tx: flags=PKT_TX_IP_CKSUM PKT_TX_TCP_SEG

4199fdea60 mbuf: generic support for TCP segmentation offload
Some of the NICs supported by DPDK have a possibility to accelerate TCP
traffic by using segmentation offload. The application prepares a packet
with valid TCP header with size up to 64K and deleguates the
segmentation to the NIC.

Implement the generic part of TCP segmentation offload in rte_mbuf. It
introduces 2 new fields in rte_mbuf: l4_len (length of L4 header in bytes)
and tso_segsz (MSS of packets).

To delegate the TCP segmentation to the hardware, the user has to:

- set the PKT_TX_TCP_SEG flag in mbuf->ol_flags (this flag implies
  PKT_TX_TCP_CKSUM)
- set the flag PKT_TX_IPV4 or PKT_TX_IPV6
- set PKT_TX_IP_CKSUM if it's IPv4, and set the IP checksum to 0 in
  the packet
- fill the mbuf offload information: l2_len, l3_len, l4_len, tso_segsz
- calculate the pseudo header checksum without taking ip_len in account,
  and set it in the TCP header, for instance by using
  rte_ipv4_phdr_cksum(ip_hdr, ol_flags)

The API is inspired from ixgbe hardware (the next commit adds the
support for ixgbe), but it seems generic enough to be used for other
hw/drivers in the future.

This commit also reworks the way l2_len and l3_len are used in igb
and ixgbe drivers as the l2_l3_len is not available anymore in mbuf.

6006818cfb net: new checksum functions
Introduce new functions to calculate checksums. These new functions
are derivated from the ones provided csumonly.c but slightly reworked.
There is still some room for future optimization of these functions
(maybe SSE/AVX, ...).

This API will be modified in tbe next commits by the introduction of
TSO that requires a different pseudo header checksum to be set in the
packet.

51f694dd40 app/testpmd: rework checksum forward engine
The csum forward engine was becoming too complex to be used and
extended (the next commits want to add the support of TSO):

- no explaination about what the code does
- code is not factorized, lots of code duplicated, especially between
  ipv4/ipv6
- user command line api: use of bitmasks that need to be calculated by
  the user
- the user flags don't have the same semantic:
  - for legacy IP/UDP/TCP/SCTP, it selects software or hardware checksum
  - for other (vxlan), it selects between hardware checksum or no
    checksum
- the code relies too much on flags set by the driver without software
  alternative (ex: PKT_RX_TUNNEL_IPV4_HDR). It is nice to be able to
  compare a software implementation with the hardware offload.

This commit tries to fix these issues, and provide a simple definition
of what is done by the forward engine:

 * Receive a burst of packets, and for supported packet types:
 *  - modify the IPs
 *  - reprocess the checksum in SW or HW, depending on testpmd command line
 *    configuration
 * Then packets are transmitted on the output port.
 *
 * Supported packets are:
 *   Ether / (vlan) / IP|IP6 / UDP|TCP|SCTP .
 *   Ether / (vlan) / IP|IP6 / UDP / VxLAN / Ether / IP|IP6 / UDP|TCP|SCTP
 *
 * The network parser supposes that the packet is contiguous, which may
 * not be the case in real life.

cf543fdbc1 app/testpmd: fix use of offload flags
In testpmd the rte_port->tx_ol_flags flag was used in 2 incompatible
manners:
- sometimes used with testpmd specific flags (0xff for checksums, and
  bit 11 for vlan)
- sometimes assigned to m->ol_flags directly, which is wrong in case
  of checksum flags

This commit replaces the hardcoded values by named definitions, which
are not compatible with mbuf flags. The testpmd forward engines are
fixed to use the flags properly.

e4a1c50e69 mbuf: get the name of offload flags
In test-pmd (rxonly.c), the code is able to dump the list of ol_flags.
The issue is that the list of flags in the application has to be
synchronized with the flags defined in rte_mbuf.h.

This patch introduces 2 new functions rte_get_rx_ol_flag_name()
and rte_get_tx_ol_flag_name() that returns the name of a flag from
its mask. It also fixes rxonly.c to use this new functions and to

66c594904a ethdev: support multiple sizes of redirection table
As 40G NIC supports different sizes (128/512/64 entries) of
redirection table from that (128 entries) of 1G and 10G NICs,
support of multiple sizes of redirection table is needed.
It includes,
* Redefine 'struct rte_eth_rss_reta' in ethdev.
  - To 'struct rte_eth_rss_reta_entry64' which contains 64
    entries and 64 bits mask.
  - Array of above new structure can be used for any number of
    redirection table entries, as long as the number is multiple
    of 64. This is quite flexible for the future expanding of
    redirection table.
* Redefinition of relevant interfaces in ethdev.
  - Interface of reta update has been redefined with new parameters.
  - Interface of reta query has been redefined with new parameters.
* Rework of 1G PMD in igb.
  - reta update has been reworked.
  - reta query has been reworked.
* Rework of 10G PMD in ixgbe.
  - reta update has been reworked.
  - reta query has been reworked.
* Rework of 40G PMD (PF only) in i40e.
  - reta update has been reworked.
  - reta query has been reworked.
* Implement relevant commands in testpmd.

fa73fe80a7 app/testpmd: change rxfreet default to 32
To improve performance by using bulk alloc or vectored RX routines, we
need to set rx free threshold (rxfreet) value to 32, so make this the
testpmd default.

Thirty-two is the minimum setting needed to enable either the
bulk alloc or vector RX routines inside the ixgbe driver, so it's
best made the default for that reason. Please see
"check_rx_burst_bulk_alloc_preconditions()" in ixgbe_rxtx.c, and
RX function assignment logic in "ixgbe_dev_rx_queue_setup()" in
the same file.

The difference in IO performance for testpmd when called without any
optional parameters, and using 10G NICs using the ixgbe driver, can be
significant - approx 25% or more.

7869536f3f mbuf: flatten struct vlan_macip
The vlan_macip structure combined a vlan tag id with l2 and l3 headers
lengths for tracking offloads. However, this structure was only used as
a unit by the e1000 and ixgbe drivers, not generally.

This patch removes the structure from the mbuf header and places the
fields into the mbuf structure directly at the required point, without
any net effect on the structure layout. This allows us to treat the vlan
tags and header length fields as separate for future mbuf changes. The
drivers which were written to use the combined structure still do so,
using a driver-local definition of it.

Reduce perf regression caused by splitting vlan_macip field. This is
done by providing a single uint16_t value to allow writing/clearing
the l2 and l3 lengths together. There is still a small perf hit to the
slow path TX due to the reads from vlan_tci and l2/l3 lengths being
separated. (<5% in my tests with testpmd with no extra params).
Unfortunately, this cannot be eliminated, without restoring the vlan
tags and l2/l3 lengths as a combined 32-bit field. This would prevent
us from ever looking to move those fields about and is an artificial tie
that applies only for performance in igb and ixgbe drivers. Therefore,
this patch keeps the vlan_tci field separate from the lengths as the
best solution going forward.

ea672a8b16 mbuf: remove the rte_pktmbuf structure
The rte_pktmbuf structure was initially included in the rte_mbuf
structure. This was needed when there was 2 types of mbuf (ctrl and
packet). As the control mbuf has been removed, we can merge the
rte_pktmbuf into the rte_mbuf structure.

Advantages of doing this:
  - the access to mbuf fields is easier (ex: m->data instead of m->pkt.data)
  - make the structure more consistent: for instance, there was no reason
    to have the ol_flags field in rte_mbuf
  - it will allow a deeper reorganization of the rte_mbuf structure in the
    next commits, allowing to gain several bytes in it

b0f4a445ea app/testpmd: allow to set part of flow control parameters
We might want to only change a parameter rather than have to set all possible
parameters, so add "partial" commands.
These commands only change the specified parameter.

To avoid duplicating code all around, a unique parser is kept. This parser uses
the .data parameter to select the right behavior.

3ebb09d02f app/testpmd: add missing autoneg field to set flow control
Following commit 2d95b84aaacb3d2d0bd70367c0530d15e0cbb14e, rte_eth_fc_conf
struct contains a autoneg field that must be set by callers.
Add this parameter to testpmd.

6f41fe75e2 eal: deprecate rte_snprintf
The function rte_snprintf serves no useful purpose. It is the
same as snprintf() for all valid inputs. Deprecate it and
replace all uses in current code.

Leave the tests for the deprecated function in place.

e9378bbc1f app/testpmd: tune default parameters
We usually use testpmd fwd to demonstrate IO forwarding throughput.
For best throughput, it has to assign special parameters to testpmd.
To make it easier to run, now set it as defalut value.
Such parameters are MBUF Mempool Cache and RX/TX threshold registers.
    MBCACHE: 250
    RX threshold registers: pthresh=8 hthresh=8 wthresh=0
    TX threshold registers: pthresh=32 hthresh=0 wthresh=0

836853d3d4 app/testpmd: increase default burst size to 32
The vpmd RX don't accept burst size less than 32.
As vPMD is set =y by default, while default testpmd burst size is 16.
Which will cause RX nothing if not assign burst size correctly.

d2121ceccd app/testpmd: rework display of Rx descriptors
i40e supports 16 and 32 bytes RX descriptors which can be configured.
It needs to check the driver type and the configuration to determine
if 16 or 32 bytes RX descriptors is being used, for reading and
displaying the different sizes of RX descriptors.
