9e5afc72c9 eal: add function to create control threads
Many parts of dpdk use their own management threads. Introduce a new
wrapper for thread creation that will be extended in next commits to set
the name and affinity.

To be consistent with other DPDK APIs, the return value is negative in
case of error, which was not the case for pthread_create().

ee27edbe0c drivers/net: share vdev data to secondary process
dpdk-procinfo, as a secondary process, cannot fetch stats for vdev.

This patch enables that by attaching the port from the shared data.
We also fill the eth dev ops, with only some ops works in secondary
process, for example, stats_get().

Note that, we still cannot Rx/Tx packets on the ports which do not
support multi-process.

5f19dee604 drivers/net: do not use private ethdev data
We introduced private rte_eth_dev_data to allow vdev to be created
both in primary process and secondary process(es). This is not
friendly to multi-process model, for example, it leads to port id
contention issue if two processes both find the data entry is free.

And to get stats of primary vdev in secondary, we must allocate
from the pre-defined array so that we can find it.

cd8c7c7ce2 ethdev: replace bus specific struct with generic dev
Public struct rte_eth_dev_info has a "struct rte_pci_device" field in it
although it is common for all ethdev in all buses.

Replacing pci specific struct with generic device struct and updating
places that are using pci device in a way to get this information from
generic device.

ffc905f3b8 ethdev: separate driver APIs
Create a rte_ethdev_driver.h file and move PMD specific APIs here.
Drivers updated to include this new header file.

There is no update in header content and since ethdev.h included by
ethdev_driver.h, nothing changed from driver point of view, only
logically grouping of APIs. From applications point of view they can't
access to driver specific APIs anymore and they shouldn't.

More PMD specific data structures still remain in ethdev.h because of
inline functions in header use them. Those will be handled separately.

1e3a958f40 ethdev: fix link autonegotiation value
There are 3 kind of link data in ethdev:
	- capabilities (rte_eth_dev_info)
	- configuration (rte_eth_conf)
	- status (rte_eth_link)

A bit-field is used for capabilities (rte_eth_dev_info.speed_capa) and
configuration (rte_eth_conf.link_speeds).
Bits are defined in ETH_LINK_SPEED_*.

Some numerical (ETH_SPEED_NUM_*) and boolean (ETH_LINK_*) values
are used for the link status (rte_eth_link.*).

There was a mistake in the comment of rte_eth_link.link_autoneg,
suggesting ETH_LINK_SPEED_[AUTONEG/FIXED] which are 0/1,
instead of ETH_LINK_[AUTONEG/FIXED] which are 1/0.

The drivers are fixed to use ETH_LINK_[AUTONEG/FIXED].

Fixes: 82113036e4 ("ethdev: redesign link speed config")

This patch removes the forward declaration of eth_kni_drv

cbc12b0a96 mk: do not generate LDLIBS from directory dependencies
The list of libraries in LDLIBS was generated from the DEPDIRS-xyz
variable. This is valid when the subdirectory name match the library
name, but it's not always the case, especially for PMDs.

The patches removes this feature and explicitly adds the proper
libraries in LDLIBS.

Some DEPDIRS-xyz variables become useless, remove them.

d5b0924ba6 ethdev: add return value to stats get dev op
The stats_get dev op API doesn't include return value, so PMD cannot
return an error in case of failure at stats getting process time.

Since PCI devices can be removed and there is a time between the
physical removal to the RMV interrupt, the user may get invalid stats
without any indication.

This patch changes the stats_get API return value to be int instead of
void.

All the net PMDs stats_get dev ops are adjusted by this patch.

4be4659a93 drivers/net: use device name from device structure
Device name resides in two different locations, in rte_device->name and
in ethernet device private data.

For now, the copy in the ethernet device private data is required for
multi process support, the name is the how secondary process finds about
primary process device.

But for drivers there is no reason to use the copy in the ethernet
device private data.

This patch updates PMDs to use only rte_device->name.
