fb7a78a12a app/testpmd: new commands for ethertype filter
Following commands of ethertype filter are removed:
  - add_ethertype_filter (port_id) ethertype (eth_value)
  - remove_ethertype_filter (port_id) index (idx)
  - get_ethertype_filter (port_id) index (idx)
New command is added for ethertype filter by using filter_ctrl API and new
ethertype filter structure:
  - ethertype_filter (port_id) (add|del) (mac_addr|mac_ignr)
    (mac_address) ethertype (ether_type) (drop|fwd) queue (queue_id)

950d15163a app/testpmd: remove duplicated function for list parsing
There were two static functions called "parse_item_list" in testpmd app.
Since one was a superset of the functionality of the other, we can
collapse the two calls down into a single one, shared between the two
C files.

eced116610 mk: fix build with shared pcap pmd
Some applications doesn't have the pcap link flag
when shared libraries are enabled.
Indeed in such case, pcap PMD must not be linked but pcap library should.

Actually -lpcap is always needed if pcap PMD is used,
and -lrte_pmd_pcap must be set only with static PMD library.
So the flags -lrte_pmd_pcap and -lpcap are enabled separately.

Workarounds in test-pmd/ and test-pipeline/ can be removed.

aaa662e75c cmdline: fix overflow on bsd
When using test-pmd with flow director in FreeBSD, the application will
segfault/Bus error while parsing the command-line. This is due to how
each commands result structure is represented during parsing, where the offsets
for each tokens value is stored in a character array(char result_buf[BUFSIZ])
in cmdline_parse()(./lib/librte_cmdline/cmdline_parse.c).

The overflow occurs where BUFSIZ is less than the size of a commands result
structure, in this case "struct cmd_pkt_filter_result"
(app/test-pmd/cmdline.c) is 1088 bytes and BUFSIZ on FreeBSD is 1024 bytes as
opposed to 8192 bytes on Linux.

The problem can be reproduced by running test-pmd on FreeBSD:
./testpmd -c 0x3 -n 4 -- -i --portmask=0x3 --pkt-filter-mode=perfect
And adding a filter:
add_perfect_filter 0 udp src 192.168.0.0 1024 dst 192.168.0.0 1024 flexbytes
0x800 vlan 0 queue 0 soft 0x17

This patch removes the OS dependency on BUFSIZ and defines and uses a
library #define CMDLINE_PARSE_RESULT_BUFSIZE 8192

Added boundary checking to ensure this buffer size cannot overflow, with
an error message being produced.

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.

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.

- 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

are not compatible with mbuf flags. The testpmd forward engines are

its mask. It also fixes rxonly.c to use this new functions and to

  - 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.

The test steps are as follows:
 1> use commands to add/delete VxLAN UDP port.
 2> use rxonly mode to receive VxLAN packet.

0069e277db app/testpmd: print message if queue start/stop is not supported
Print an error message to the user when trying to start/stop a rx/tx queue and
this function is not supported by the PMD driver. The patch does not check if
the return value is -EINVAL because testpmd is already validating the port and
queue id.

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.

bfd5051b43 app/testpmd: new command to get extended statistics
Add a new token in "show port" command to dump the extended statistics
of a device. It validates the new xstats framework added in previous commit.

4332beee95 mbuf: expand ol_flags field to 64-bits
The offload flags field (ol_flags) was 16-bits and had no further room
for expansion. This patch increases the field size to 64-bits, using up
the remaining reserved space in the single-cache-line mbuf.

NOTE: none of the values for existing flags have been changed, i.e. no
new numbers have been explicitly reserved between existing flag
definitions.

08b563ffb1 mbuf: replace data pointer by an offset
The mbuf structure already contains a pointer to the beginning of the
buffer (m->buf_addr). It is not needed to use 8 bytes again to store
another pointer to the beginning of the data.

Using a 16 bits unsigned integer is enough as we know that a mbuf is
never longer than 64KB. We gain 6 bytes in the structure thanks to
this modification.

* Updated to apply to latest on mainline.
* Disabled vector PMD in config as it relies heavily on the mbuf layout
  This will be re-enabled in a subsequent commit once vPMD has been
  reworked to take account of mbuf changes.

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
