4630290af4 mbuf: move pool pointer in first half
According to the Technical Board decision
(http://mails.dpdk.org/archives/dev/2020-November/191859.html),
the mempool pointer in the mbuf struct is moved
from the second to the first half.
It may increase performance in some cases
on systems having 64-byte cache line, i.e. mbuf split in two cache lines.

Due to this change, all fields after "pool" are moved up.
Hopefully no vector data path is impacted.

Moving this field gives more space to dynfield1
while dropping the temporary dynfield0.

This is how the mbuf layout looks like (pahole-style):

word  type                              name                byte  size

d965af9e8a kni: increase kernel version requirement for VA
A build error reported related to the selected 'get_user_pages_remote()'
kernel API:

.../kernel/linux/kni/kni_dev.h:113:8:
  error: too few arguments to function ‘get_user_pages_remote’
  ret = get_user_pages_remote(tsk, tsk->mm, iova, 1
        ^~~~~~~~~~~~~~~~~~~~~

Currently there are three versions of the 'get_user_pages_remote()'
supported, based on kernel version < 4.9, = 4.9, > 4.9.

These version based checks are not working fine with the distro kernels
which is the cause of reported build error. The error reported by the
kernel version 4.8, but it is using API defined in > 4.9.

To be able to take control of this, and possible more, related build
error, increasing the minimum supported kernel version for iova=va with
KNI to kernel version 4.9.

This leaves us with single version of the kernel API and more manageable.

Since the library versioning for both stable and experimental ABI's is

The replacement in Makefiles was done using the following regex:

	^(#.*\n)?LIBABIVER\s*:=\s*\d+\n(\s*\n)?

(LIBABIVER := numbers, optionally preceded by a comment and optionally
succeeded by an empty line)

The replacement for meson files was done using the following regex:

	^(#.*\n)?version\s*=\s*\d+\n(\s*\n)?

(version = numbers, optionally preceded by a comment and optionally
succeeded by an empty line)

a0dede62a5 eal/linux: remove KNI restriction on IOVA
Now that KNI supports VA (with kernel versions starting 4.6.0), we can
accept IOVA as VA, but KNI must be configured for this.
Pass iova_mode when creating KNI netdevs.

So far, IOVA detection policy forced IOVA as PA when KNI is loaded,
whatever the buses IOVA requirements were.

We can now use IOVA as VA, but this comes with a cost in KNI.
When no constraint is expressed by the buses, keep the current behavior
of choosing PA.

Note: this change supposes that dpdk is built on the same kernel than
the target system kernel; no objection has been expressed on this topic.

In rte_mempool_populate_default(), trying to allocate whole block of

several memzones that have different physical address and virtual address
offsets. The rte_mempool_populate_default() is used by

18218713bf enforce experimental tag at beginning of declarations
Putting a '__attribute__((deprecated))' in the middle of a function

Move the tag on a separate line and make it the first thing of function
prototypes.
This is not perfect but we will trust reviewers to catch the other not
so easy to detect patterns.

     $(git grep -l __rte_experimental -- '*.h')

Special mention for rte_mbuf_data_addr_default():

There is either a bug or a (not yet understood) issue with gcc.
gcc won't drop this inline when unused and rte_mbuf_data_addr_default()
calls rte_mbuf_buf_addr() which itself is experimental.
This results in a build warning when not accepting experimental apis
from sources just including rte_mbuf.h.

For this specific case, we hide the call to rte_mbuf_buf_addr() under
the ALLOW_EXPERIMENTAL_API flag.

ea6b39b5b8 kni: remove ethtool support
Current design requires kernel drivers and they need to be probed by
Linux up to some level so that they can be usable by DPDK for ethtool
support, this requires maintaining the Linux drivers in DPDK.

Also ethtool support is limited and hard, if not impossible, to expand
to other PMDs.

Since KNI ethtool support is not used commonly, if not used at all,
removing the support for the sake of simplicity and maintenance.

This error can be raised:

	'req' may be used uninitialized in this function

It should not happen because kni_fifo_get() would return 0 if
req is not initialized, so the function would return before using req.
But GCC complains about it in -O1 optimization,
and a NULL initialization is harmless here.

edd2fafbc0 kni: allocate memory dynamically for each device
Long time ago preallocation of memory for KNI was introduced in commit

allocated memzones, which led to memzone exhaustion. Currently memzones
can be freed and this patch uses this ability for dynamic KNI memory
allocation.

a9dbe18022 fix ethdev port id validation
Some DPDK applications wrongly assume these requirements:
    - no hotplug, i.e. ports are never detached
    - all allocated ports are available to the application

Such application assume a valid port index is in the range [0..count[.

There are three consequences when using such wrong design:
    - new ports having an index higher than the port count won't be valid
    - old ports being detached (RTE_ETH_DEV_UNUSED) can be valid

Such mistake will be less common with growing hotplug awareness.
All applications and examples inside this repository - except testpmd -
must be fixed to use the function rte_eth_dev_is_valid_port.
