When device is be hot-unplugged, the vfio kernel module will sent req
notifier to request user space to release the allocated resources at
first. After that, vfio kernel module will detect the device disappear,
and then delete the device in kernel.
This patch aim to add req notifier processing to enable hotplug for vfio.

In the current code, on some cases the representor ethdev is using the
PF interface to query some link status information or pause parameters.
It was done because in previous kernel versions there was no support
from the kernel for the representor info.
Using the PF i/f for such ioctl is error prone and not always working
because:
* On some cases there is no PF at all, only representors (e.g Bluefield
with host representors)
* Query the up/down status from representor and link status from PF
is in-consist
* PF link is down doesn't necessarily means representor is down.
* setting different pause configuration for the PF and the
representors will result on undefined behaviour
Making the code cleaner and more robust by using only the representor
i/f for the ioctl. whatever the kernel will provide on this query will
be used. No need to do W.A. for kernel missing functionality.
Note:
1. Setting pause parameters will obviously won't work on representors
2. Old kernel will not report all the possible representor info

In current implementation the calculation of the flow size is done
during the validation stage, and the same function is also used to
translate the input parameters into verbs spec. This is hard to
maintain and error prone.
Another issue is dev-flows (flows that are created implicitly in order
to support the requested flow for example when the user request RSS on
UDP 2 rules need to be created one for IPv4 and one for IPv6).
In current implementation the dev-flows are created on the same
memory allocation. This will be harder to implement in future drivers.
The commits extract the calculation and creation of the dev-flow from
the translation part (the part that converts the parameters into the
format required by the driver). This results in that the prepare
function only function is to allocate the dev-flow.

In current implementation the validation logic reside in the same
function that calculates the size of the verbs spec and also create the
verbs spec.
This approach results in hard to maintain code which can't be shared.
also in current logic there is a use of parser entity that holds the
information between function calls. The main problem with this parser is
that it assumes the connection between different functions. For example
it assumes that the validation function was called and relevant values
were set.
This may result in an issue if and when we only call the validation
function, or call the apply function without the validation (Currently
according to RTE flow we must call validation before creating flow, but
if we want to change that to save time during flow creation, for example
the user validated some rule and just want to change the IP there is no
true reason the validate the rule again).
This commit address both of those issues by extracting the validation
logic into detected functions and remove the use of the parser object.
The side effect of those changes is that in some cases there will be a
need to traverse the item list again.

Add the vectorized version of the no-scatter Rx handler. It aims to
process 8 descriptors per loop using AVX2 SIMD instructions. This
handler is in its own file enic_rxtx_vec_avx2.c, and makefile and
meson.build are modified to compile it when the compiler supports
AVX2. Under ideal conditions, the vectorized handler reduces
cycles/packet by more than 30%, when compared against the no-scatter
Rx handler. Most implementation ideas come from i40e's AVX2 based
handler, so credit goes to its authors.
At this point, the new handler is meant for field trials, and is not
selected by default. So add a new devarg enable-avx2-rx to allow the
user to request the use of the new handler. When enable-avx2-rx=1, the
driver will consider using the new handler.
Also update the guide doc and introduce the vectorized handler.

All information about a device to probe can be grouped
in a common string, which is what we usually call devargs.
An application should not have to parse this string before
calling the EAL probe function.
And the syntax could evolve to be more complex and support
matching multiple devices in one string.
That's why the bus name and device name should be removed from
rte_eal_hotplug_add().
Instead of changing this function, a simpler one is added
and used in the old one, which may be deprecated later.
When removing a device, we already know its rte_device handle
which can be directly passed as parameter of rte_eal_hotplug_remove().
If the rte_device is not known, it can be retrieved with the devargs,
by iterating in the device list (future RTE_DEV_FOREACH()).
Similarly to the probing case, a new function is added
and used in the old one, which may be deprecated later.
The new function is used in failsafe, because the replacement is easy.

When adding or removing external memory from the memory map, there
may be actions that need to be taken on account of this memory (e.g.
DMA mapping). Add support for triggering callbacks when adding,
removing, attaching or detaching external memory.
Some memory event callback handlers will need additional logic to
handle external memory regions. For example, virtio callback has to
completely ignore externally allocated memory, because there is no
way to find file descriptors backing the memory address in a
generic fashion. All other callbacks have also been adjusted to

All current calls for memseg walk functions were adjusted to

Mempools is a special case, because we may be asked to allocate
a mempool on a specific socket, and we need to ignore all page

If there is a event available qman portal fd will be set
and the function will be awakened. If no event is available,
it will only wait till the given timeout value.
In case of interrupt the timeout ticks are used as usecs.

Make the -Wno-format-nonliteral flag conditional, and only set in
clang and gcc builds, since this flag is not supported (nor needed)
when building dsw with icc.

Currently, DPDK will skip mapping some areas (or even an entire BAR)
if MSI-X table happens to be in them but is smaller than page size.
Kernels 4.16+ will allow mapping MSI-X BARs [1], and will report this
as a capability flag. Capability flags themselves are also only
supported since kernel 4.6 [2].
This commit will introduce support for checking VFIO capabilities,
and will use it to check if we are allowed to map BARs with MSI-X
tables in them, along with backwards compatibility for older
kernels, including a workaround for a variable rename in VFIO
region info structure [3].

This commit adds a unit test that checks the behaviour
of the unlinks_in_progress() function, ensuring that the
returned values are the number of unlinks requested,
until the scheduler runs and "acks" the requests, after
which the count should be zero again.

This commit adds a counter to each port, which counts the
number of unlinks that have been performed. When the scheduler
thread starts its scheduling routine, it "acks" all unlinks that
have been requested, and the application is gauranteed that no
more events will be scheduled to the port from the unlinked queue.

This commit fixes the cq index checks when unlinking
ports/queues while the scheduler core is running.
Previously, the == comparison could be "skipped" if
in particular corner cases. With the check being changed
to >= this is resolved as the cq idx gets reset to zero.

This patch enhances:
1. Configure the dequeue time out value as per the given
method or per dequeue, global or default.
2. The timeout values were being mixed as ns or ms timeouts,
Now the values are stored as ns and scale is in ms.
