0c0e46c36b net/nfp: fix mbufs releasing when stop or close
PMDs have the responsibility of releasing mbufs sent through xmit burst
function. NFP PMD attaches those sent mbufs to the TX ring structure,
and it is at the next time a specific ring descriptor is going to be
used when the previous linked mbuf, already transmitted at that point,
is released. Those mbufs belonging to a chained mbuf got its own link
to a ring descriptor, and they are released independently of the mbuf
head of that chain.

The problem is how those mbufs are released when the PMD is stopped or
closed. Instead of releasing those mbufs as the xmit functions does,
this is independently of being in a mbuf chain, the code calls
rte_pktmbuf_free which will release not just the mbuf head in that
chain but all the chained mbufs. The loop will try to release those
mbufs which have already been released again when chained mbufs exist.

This patch fixes the problem using rte_pktmbuf_free_seg instead.

c7e9729da6 net/nfp: support CPP
CPP refers to the internal NFP Command Push Pull bus. This patch allows
to create CPP commands from user space allowing to access any single
part of the chip.

This CPP interface is the base for having other functionalities like
mutexes when accessing specific chip components, chip resources management,
firmware upload or using the NSP, an embedded arm processor which can
perform tasks on demand.

NSP was the previous only way for doing things in the chip by the PMD,
where a NSPU interface was used for commands like firmware upload or
port link configuration. CPP interface supersedes NSPU, but it is still
possible to use NSP through CPP.

CPP interface adds a great flexibility for doing things like extended
stats or firmware debugging.

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.

cebe3d7b3d ethdev: remove useless parameter in callback process
The pointer to the user parameter of the callback registration is
automatically pass to the callback function.
There is no point to allow changing this user parameter by a caller.
That's why this parameter is always set to NULL by PMDs and set only
in ethdev layer before calling the callback function.

The history is that the user parameter was initially used
by the callback implementation to pass some information
between the application and the driver:
	c1ceaf3ad0 ("ethdev: add an argument to internal callback function")
Then a new parameter has been added to leave the user parameter
to its standard usage of context given at registration:
	d6af1a13d7 ("ethdev: add return values to callback process API")

The NULL parameter in the internal callback processing function
is now removed. It makes clear that the callback parameter is user
managed and opaque from a DPDK point of view.

Existing vlan_offload_set_t vectors are modified to return

Finally, a vlan_offload_set_t vector is added to virtio
to facilitate dynamically turning VLAN strip on or off.

380a7aab1a mbuf: rename deprecated VLAN flags
PKT_RX_VLAN_PKT and PKT_RX_QINQ_PKT are deprecated for a while.
As explained in [1], these flags were kept to let the applications and
PMDs move to the new flag. There is also a need to support Rx vlan
offload without vlan strip (at least for the ixgbe driver).

This patch renames the old flags for this feature, knowing that some
PMDs were using PKT_RX_VLAN_PKT and PKT_RX_QINQ_PKT to indicate that
the vlan tci has been saved in the mbuf structure.

It is likely that some PMDs do not set the proper flags when doing vlan
offload, and it would be worth making a pass on all of them.
