96c0450dff ixgbe: fix dropping packets from unsupported Tx queues
Ixgbe HW supports 128 TX queues. However, the full 128 queues are only
available in VT and DCB mode.  In normal default "none" mode (VT/DCB off)
the maximum number of available queues is only 64.

The driver doesn't check the mode when reporting the available
number of queues, allowing more that 64 queues to be used in all cases.
If a queue no. >=64 is used in default mode, the TX packets will be dropped
silently.

This change adds a check to forbid using a queue number larger than 64
during device configuration (in default mode), so that the problem is
reported as early as possible.

Fixes: 27b609cbd1 ("ethdev: move the multi-queue mode check to specific drivers")

4d803a7246 mlx5: support HW packet padding
Environment variable MLX5_PMD_ENABLE_PADDING enables HW packet padding
in PCI bus transactions.

When packet size is cache aligned and CRC stripping is enabled, 4 fewer
bytes are written to the PCI bus. Enabling padding makes such packets
aligned again.

In cases where PCI bandwidth is the bottleneck, padding can improve
performance by 10%.

This is disabled by default since this can also decrease performance for
unaligned packet sizes.

ae19955e7c i40evf: support reporting PF reset
When Linux PF and DPDK VF are used for i40e PMD, when a PF reset occurs,
an interrupt will go via adminq event to inform the VF of the reset.
A callback mechanism is introduced for the VF to allow it to invoke a
registered callback when PF  reset happens.

Users can register a callback for this interrupt event using:
  rte_eth_dev_callback_register(portid,
		RTE_ETH_EVENT_INTR_RESET,

ee584e9710 vhost: add driver on top of the library
The patch introduces a new PMD. This PMD is implemented as thin wrapper
of librte_vhost. It means librte_vhost is also needed to compile the PMD.
The vhost messages will be handled only when a port is started. So start
a port first, then invoke QEMU.

The PMD has 2 parameters.
 - iface:  The parameter is used to specify a path to connect to a
           virtio-net device.
 - queues: The parameter is used to specify the number of the queues
           virtio-net device has.
           (Default: 1)

Here is an example.
$ ./testpmd -c f -n 4 --vdev 'eth_vhost0,iface=/tmp/sock0,queues=1' -- -i

To connect above testpmd, here is qemu command example.

$ qemu-system-x86_64 \
        <snip>
        -chardev socket,id=chr0,path=/tmp/sock0 \
        -netdev vhost-user,id=net0,chardev=chr0,vhostforce,queues=1 \

2fdd835f99 vmxnet3: support jumbo frames
Add support for linking multi-segment buffers together to
handle Jumbo packets. The vmxnet3 API supports having header
and body buffer types. What this patch does is fill the primary
ring completely with header buffers and the secondary ring
with body buffers. This allows for non-jumbo frames to only
use one mbuf (from primary ring); and jumbo frames will have
first mbuf from primary ring and following mbufs from other
ring.

This could be optimized in future if the DPDK had API
to supply different sized mbufs (two pools) into driver.

eb57d9b750 fm10k: setup Rx interrupt for PF and VF
In interrupt mode, each rx queue can have one interrupt to notify the
application when packets are available in that queue. Some queues
also can share one interrupt.
Currently, fm10k needs one separate interrupt for mailbox. So, only those
drivers which support multiple interrupt vectors e.g. vfio-pci can work
in fm10k interrupt mode.
This patch uses the RXINT/INT_MAP registers to map interrupt causes
(rx queue and other events) to vectors, and enable these interrupts
through kernel drivers like vfio-pci.

6be3dfec31 ixgbe: support link speed auto-negotiation on X550em_x
Normally the auto-negotiation is supported by FW. SW need not care about
that. But on x550em_x, FW doesn't support auto-neg. As the x550em_x ports
are 10G, if we connect the port will a peer which is 1G, the link will
always be down.
We need support auto-neg by SW to avoid this link down issue. As we already
have the code to handle the link speed setting, what we need is a trigger.
When the advertised link speed changes, a PHY interruption will be
triggered. So, we should handle this interrupt and call ixgbe_handle_lasi
to set the link speed correctly.

Please be aware it's working when auto-neg is on. If the auto-neg of the
peer port is turned off and its speed is indicated manually, we should also
set the speed of our own port manually.

72dec9e37a ixgbe: support multicast promiscuous mode on VF
Add multicast promiscuous mode support on ixgbe VF driver.

Please note if we want to use this promiscuous mode, we need both PF
and VF driver to support it. The reason is this VF feature is
configged on PF.
If use kernel PF driver + dpdk VF driver, make sure kernel PF driver
support VF multicast promiscuous mode. If use dpdk PF + dpdk VF,
better make sure PF driver is the same version as VF.

0cf7c6a6f3 ixgbe/base: set MDIO speed after MAC reset
The MDIO clock speed must be reconfigured after the MAC reset.
The MDIO clock speed becomes invalid, therefore the driver reads
invalid PHY register values. The driver now set the MDIO clock
speed prior to initializing PHY ops and again after the MAC reset.

As now the MDIO speed gets set in more than one place, make a
function for it so it will always be done correctly.

e2f368a4bf ixgbe/base: fix setting flow director flag twice
Do not set FDIRCTRL.DROP_NO_MATCH in ixgbe_init_fdir_perfect_82599(),
this bit is already set in ixgbe_set_fdir_drop_queue_82599() which
makes more sense for drivers that call that function.

This resolves an issue where packets were being dropped when switching
to perfect filters mode.

Setting this bit makes no sense in perfect filters mode for the
driver as we do not want to route all packets that don't match an FDIR
rule to a single queue and instead fall back to RSS.
Drivers that need this bit set can call ixgbe_set_fdir_drop_queue_82599()
and the ones that don't, can preserve the old behavior.

This patch adds a new function to the EAL API:
int rte_eal_primary_proc_alive(const char *path);

The function indicates if a primary process is alive right now.
This functionality is implemented by testing for a write-
lock on the config file, and the function tests for a lock.

The use case for this functionality is that a secondary
process can wait until a primary process starts by polling
the function and waiting. When the primary is running, the
secondary continues to poll to detect if the primary process
has quit unexpectedly, the secondary process can detect this.

b2bb3a5daa mk: stop on warning only in developer build
Add RTE_DEVEL_BUILD make-variable which can be used to do things
differently when doing development vs building a release,
autodetected from source root .git presence and overridable via
commandline. It is used it to enable -Werror compiler flag and may
be extended to other checks.

Failing build on warnings is a useful developer tool but its bad
for release tarballs which can and do get built with newer
compilers than what was used/available during development. Compilers
routinely add new warnings so code which built silently with cc X
might no longer do so with X+1. This doesn't make the existing code
any more buggier and failing the build in this case does not help
to improve the quality of an already released version either.

This change the default flags which can be tuned with EXTRA_CFLAGS.

simple linker script which achieves the same without all the problems,

Since creating the linker script is practically zero cost, remove the
config option and just create it always.

optimization through loop unwinding, and also the most dramatic use of
case label fall-through.

In this implementation, while() loop is used because we could not assume
count is strictly positive. Using while() loop saves one line of check.

5499c1fc9b examples/vhost: fix mbuf allocation
How to reproduce:

1. Start vhost-switch
./examples/vhost/build/vhost-switch -c 0x3 -n 4 -- -p 1 --stat 0
2. Start VM with a virtio port
$ $QEMU -smp cores=2,sockets=1 -m 4G -cpu host -enable-kvm \
  -chardev socket,id=char1,path=<path to vhost-user socket> \
  -device virtio-net-pci,netdev=vhostuser1 \
  -netdev vhost-user,id=vhostuser1,chardev=char1
  -object memory-backend-file,id=mem,size=4G,mem-path=<hugetlbfs path>,share=on \
  -numa node,memdev=mem -mem-prealloc \
  -hda <path to VM img>
3. Start l2fwd in VM
$ ./examples/l2fwd/build/l2fwd -c 0x1 -n 4 -m 1024 -- -p 0x1
4. Use ixia to inject packets in a small data bit rate.

Error:

vhost-switch keeps printing error message:
failed to allocate memory for mbuf.

Root cause:

How many mbufs allocated for a port is calculated by below formula.
NUM_MBUFS_PER_PORT = ((MAX_QUEUES*RTE_TEST_RX_DESC_DEFAULT) + \
(num_switching_cores*MAX_PKT_BURST) + \
(num_switching_cores*RTE_TEST_TX_DESC_DEFAULT) +\
(num_switching_cores*MBUF_CACHE_SIZE))
We suppose num_switching_cores is 1 and MBUF_CACHE_SIZE is 128.
And when initializing port, master core fills mbuf mempool cache,
so there would be some left in that cache, for example 121.
So total mbufs which can be used is:
(MAX_PKT_BURST + MBUF_CACHE_SIZE - 121) = (32 + 128 - 121) = 39.
What makes it worse is that there is a buffer to store mbufs
(which will be tx_burst to physical port), if it occupies some mbufs,
there will be possible < 32 mbufs left, so vhost dequeue prints out
this msg.

In all, it fails to include master core's mbuf mempool cache.

859b480d5a vhost: add guest offload setting
Add guest offload setting in vhost lib.

Virtio 1.0 spec (5.1.6.4 Processing of Incoming Packets) says:

    1. If the VIRTIO_NET_F_GUEST_CSUM feature was negotiated, the
       VIRTIO_NET_HDR_F_NEEDS_CSUM bit in flags can be set: if so,
       the packet checksum at offset csum_offset from csum_start
       and any preceding checksums have been validated. The checksum
       on the packet is incomplete and csum_start and csum_offset
       indicate how to calculate it (see Packet Transmission point 1).

    2. If the VIRTIO_NET_F_GUEST_TSO4, TSO6 or UFO options were
       negotiated, then gso_type MAY be something other than
       VIRTIO_NET_HDR_GSO_NONE, and gso_size field indicates the
       desired MSS (see Packet Transmission point 2).

In order to support these features, the following changes are added,

1. Extend 'VHOST_SUPPORTED_FEATURES' macro to add the offload features negotiation.

2. Enqueue these offloads: convert some fields in mbuf to the fields in virtio_net_hdr.

There are more explanations for the implementation.

For VM2VM case, there is no need to do checksum, for we think the
  data should be reliable enough, and setting VIRTIO_NET_HDR_F_NEEDS_CSUM
  at RX side will let the TCP layer to bypass the checksum validation,
  so that the RX side could receive the packet in the end.

In terms of us-vhost, at vhost RX side, the offload information is
  inherited from mbuf, which is in turn inherited from TX side. If we
  can still get those info at RX side, it means the packet is from
  another VM at same host. So, it's safe to set the
  VIRTIO_NET_HDR_F_NEEDS_CSUM, to skip checksum validation.

6ba1f63b5a virtio: support specification 1.0
Modern (v1.0) virtio pci device defines several pci capabilities.
Each cap has a configure structure corresponding to it, and the
cap.bar and cap.offset fields tell us where to find it.

Firstly, we map the pci resources by rte_eal_pci_map_device().
We then could easily locate a cfg structure by:

    cfg_addr = dev->mem_resources[cap.bar].addr + cap.offset;

Therefore, the entrance of enabling modern (v1.0) pci device support
is to iterate the pci capability lists, and to locate some configs
we care; and they are:

- common cfg

  For generic virtio and virtqueue configuration, such as setting/getting
  features, enabling a specific queue, and so on.

- nofity cfg

  Combining with `queue_notify_off' from common cfg, we could use it to
  notify a specific virt queue.

- device cfg

  Where virtio_net_config structure is located.

- isr cfg

  Where to read isr (interrupt status).

If any of above cap is not found, we fallback to the legacy virtio
handling.

If succeed, hw->vtpci_ops is assigned to modern_ops, where all
operations are implemented by reading/writing a (or few) specific
configuration space from above 4 cfg structures. And that's basically
how this patch works.

Besides those changes, virtio 1.0 introduces a new status field:
FEATURES_OK, which is set after features negotiation is done.

Last, set the VIRTIO_F_VERSION_1 feature flag.

fae202e2e2 mk: introduce new install syntax
The old install command was:
	make install T=x86_64-native-linuxapp-gcc DESTDIR=install
It still works and can be replaced by these more standard commands:
	make config T=x86_64-native-linuxapp-gcc 0=x86_64-native-linuxapp-gcc
	make O=x86_64-native-linuxapp-gcc
	make install O=x86_64-native-linuxapp-gcc prefix= DESTDIR=install

It means the "make install" do not perform any compilation anymore when T
is not used. It is done only in pre_install to keep compatibility with the
old syntax based on T= option.

The default prefix /usr/local is empty in the T= case which is
used only for a local install.

The rule "install" follows these conventions:
http://gnu.org/prep/standards/html_node/Directory-Variables.html
http://gnu.org/prep/standards/html_node/DESTDIR.html

The variable sdkdir has been added to the more standards ones,
to configure the directory used with RTE_SDK when using the DPDK makefiles
to build an application.

It is still possible to build DPDK with the "install T=" rule without
specifying any DESTDIR. In such case there is no install, as before.

The old usage of an installed SDK is:
    make -C examples/helloworld RTE_SDK=$(readlink -m $DESTDIR) \
         RTE_TARGET=x86_64-native-linuxapp-gcc
RTE_TARGET can be specified but is useless now with an installed SDK.

This PMD is dependent on Intel's multibuffer library, see the whitepaper

Processors", see ref 1 for details on the library's design and ref 2 to
download the library itself. This initial implementation is limited to
supporting the chained operations of "hash then cipher" or "cipher then

  - RTE_CRYPTO_CIPHER_AES_CBC (with 128-bit, 192-bit and 256-bit keys supported)

Authentication algorithms:
  - RTE_CRYPTO_AUTH_SHA1_HMAC
  - RTE_CRYPTO_AUTH_SHA256_HMAC
  - RTE_CRYPTO_AUTH_SHA512_HMAC
  - RTE_CRYPTO_AUTH_AES_XCBC_MAC

Important Note:
Due to the fact that the multi-buffer library is designed for
accelerating IPsec crypto operation, the digest's generated for the HMAC
functions are truncated to lengths specified by IPsec RFC's, ie RFC2404
for using HMAC-SHA-1 with IPsec specifies that the digest is truncate
from 20 to 12 bytes.

Build instructions:
To build DPDK with the AESNI_MB_PMD the user is required to download
(ref 2) and compile the multi-buffer library on there system before
building DPDK. The environmental variable AESNI_MULTI_BUFFER_LIB_PATH
must be exported with the path where you extracted and built the multi
buffer library and finally set CONFIG_RTE_LIBRTE_PMD_AESNI_MB=y in
config/common_linuxapp.

Current status: It's doesn't support crypto operation
across chained mbufs, or cipher only or hash only operations.

1703e94ac5 qat: add driver for QuickAssist devices
This patch adds a PMD for the Intel Quick Assist Technology DH895xxC
hardware accelerator.

This patch depends on a QAT PF driver for device initialization. See
the file docs/guides/cryptodevs/qat.rst for configuration details

This patch supports a limited subset of QAT device functionality,
currently supporting chaining of cipher and hash operations for the
following algorithmsd:

Cipher algorithms:
  - RTE_CRYPTO_CIPHER_AES_CBC (with 128-bit, 192-bit and 256-bit keys supported)

Hash algorithms:
  - RTE_CRYPTO_AUTH_SHA1_HMAC
  - RTE_CRYPTO_AUTH_SHA256_HMAC
  - RTE_CRYPTO_AUTH_SHA512_HMAC
  - RTE_CRYPTO_AUTH_AES_XCBC_MAC

Some limitation on this patchset which shall be contributed in a
subsequent release:
 - Chained mbufs are not supported.
 - Hash only is not supported.
 - Cipher only is not supported.
 - Only in-place is currently supported (destination address is
   the same as source address).
 - Only supports session-oriented API implementation (session-less
   APIs are not supported).

78c8709b5d mbuf_offload: introduce library to attach offloads to mbuf
This library add support for adding a chain of offload operations to a
mbuf. It contains the definition of the rte_mbuf_offload structure as
well as helper functions for attaching  offloads to mbufs and a mempool
management functions.

This initial implementation supports attaching multiple offload
operations to a single mbuf, but only a single offload operation of a
specific type can be attach to that mbuf.

33cf6be04d ethdev: add sanity checks to functions
The functions rte_eth_rx_queue_count and rte_eth_descriptor_done are
supported by very few PMDs. Therefore, it is best to check for support
for the functions in the ethdev library, so as to avoid run-time crashes
at run-time if the application goes to use those APIs. Similarly, the
port parameter should also be checked for validity.

71594065e2 ethdev: remove duplicated debug functions
The functions for rx/tx burst, for rx_queue_count and descriptor_done in
the ethdev library all had two copies of the code. One copy in
rte_ethdev.h was inlined for performance, while a second was in
rte_ethdev.c for debugging purposes only. We can eliminate the second
copy of the functions by moving the additional debug checks into the
copies of the functions in the header file. [Any compilation for
debugging at optimization level 0 will not inline the function so the
result should be same as when the function was in the .c file.]
