Change rte_hash*_create() functions to return NULL and set rte_errno to

described in the API documentation in the header file.
These functions were returning a pointer to the existing object in that

Doing this change also makes the hash API more consistent with the other

The purpose of this patch is used to add a new field
"class" in rte_pci_id structure. The new class field includes
class_id, subcalss_id, programming interface of a pci device.
With this field, we can identify pci device by its class info,
which can be more flexible instead of probing the device by
vendor_id OR device_id OR subvendor_id OR subdevice_id.
For example, we can probe all nvme devices by class field, which
can be quite convenient.

of an ethernet port. Specifically:
- it allows to define a set of advertised speeds for

- it allows to disable link auto-negociation (single fixed speed).

A flag autoneg in struct rte_eth_link indicates if link speed was a

Hash library used a function pointer to choose a different
key compare function, depending on the key size.
As a result, multiple processes could not use the same hash table,
as the function addresses vary from one process to another.
Instead, a jump table is used, so each process has its own
function addresses, accessing this table with an index stored
in the hash table (note that using a custom key compare function
is not supported in multi-process mode).

As a example to use ptype info, l3fwd needs firstly to use
rte_eth_dev_get_supported_ptypes() API to check if device and/or
its PMD driver will parse and fill the needed packet type; if not,
use the newly added option, --parse-ptype, to analyze it in the
callback softly.
As the mode of EXACT_MATCH uses the 5 tuples to caculate hash, so
we narrow down its scope to:
a. ip packets with no extensions, and
b. L4 payload should be either tcp or udp.
Note: this patch does not completely solve the issue, "cannot run
l3fwd on virtio or other devices", because hw_ip_checksum may be
not supported by the devices. Currently we can:
a. remove this requirements, or
b. wait for virtio front end (pmd) to support it.

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.

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.

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 \

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.
