4a4ccf8a22 kni: fix meson warning about console keyword
Since kni no longer includes the ethtool code and so is faster to build, we
no longer need the console parameter to have incremental screen updates as
it builds. Therefore, we drop the keyword which removes the warning.

de480bbf13 kni: fix build with Linux 4.9.x
The 'get_user_pages_remote()' API is updated in kernel 4.10.0 [1],
but the check added as > 4.9.0,
this logic is broken for kernels 4.9.x, because they justify
> 4.9.0 check but have the old API.

Fixing the check as >= 4.10.0

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.

37a95bbff0 kernel/freebsd: always use clang for kmod compilation
Clang is the system compiler for FreeBSD and kernel module builds can fail
when built with gcc, e.g. when testing with test-meson-builds.sh.
Therefore, it's safer to always use clang to build the kmods since the
actual flags used are outside of DPDK's control and cannot be guaranteed to
work with all compilers.

e73831dc6c kni: support userspace VA
Patch adds support for kernel module to work in IOVA = VA mode by
providing address translation routines to convert userspace VA to
kernel VA.

KNI performance using PA is not changed by this patch.
But comparing KNI using PA to KNI using VA, the latter will have lower
performance due to the cost of the added translation.

This translation is implemented only with kernel versions starting 4.6.0.

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.

4c820b22c0 kni: fix build on RHEL 8
'ndo_change_mtu_rh74' was changed to 'ndo_change_mtu' in RHEL8.

Build error log:
/home/dpdk-18.11/kernel/linux/kni/compat.h:107:24: error: ‘const struct
net_device_ops’ has no member named ‘ndo_change_mtu_rh74’; did you mean
‘ndo_change_mtu’?

c6c36fe28a kni: fix build on Linux < 3.14
The atomic functions smp_load_acquire() and smp_store_release()
were introduced in Linux 3.14. Older kernels miss the functions:

kni_fifo.h:19:2: error:
	implicit declaration of function ‘smp_load_acquire’
kni_fifo.h:30:2: error:
	implicit declaration of function ‘smp_store_release’

The fallback is to drop the atomic barrier, as it was before
the commit below.

Fixes: 711859cd0d ("kni: fix kernel FIFO synchronization")

89397a01ce kni: set default carrier state of interface
Add module parameter 'carrier='on|off' to set the default carrier state
for linux network interfaces created by the KNI module.  The default
carrier state is 'off'.

For KNI interfaces which need to reflect the carrier state of
a physical Ethernet port controlled by the DPDK application, the
default carrier state should be left set to 'off'.  The application
can set the carrier state of the KNI interface to reflect the state
of the physical Ethernet port using rte_kni_update_link().

For KNI interfaces which are purely virtual, the default carrier
state can be set to 'on'.  This enables the KNI interface to be
used without having to explicity set the carrier state to 'on'
using rte_kni_update_link().

a9460a0b2e kni: fix build on Linux 4.19
The build error observed with Linux kernel 4.19 when KNI ethtool
support enabled (CONFIG_RTE_KNI_KMOD_ETHTOOL=y)

.../build/build/kernel/linux/kni/kni_ethtool.c:193:3:
   error: ‘struct ethtool_ops’ has no member named ‘get_settings’;
  .get_settings  = kni_get_settings,
   ^~~~~~~~~~~~

.../build/build/kernel/linux/kni/kni_ethtool.c:194:3:
   error: ‘struct ethtool_ops’ has no member named ‘set_settings’;
  .set_settings  = kni_set_settings,
   ^~~~~~~~~~~~

With kernel 4.19 ethtool_ops `get_settings` & `set_settings` are
replaced with `get_link_ksettings` & `set_link_ksettings`
Commit 9b3004953503 ("ethtool: drop get_settings and set_settings callbacks")

This fix practically removes `get_settings` & `set_settings` support
for the kernel versions that have the new ethtool_ops without
implementing the new ones.

70efa41164 igb_uio: fix unexpected removal for hot-unplug
When a device is hot-unplugged, pci_remove will be invoked unexpectedly
before pci_release, it will caused kernel hung issue which will throw the
error info of "Trying to free already-free IRQ XXX". And on the other hand,
if pci_remove before pci_release, the interrupt will not got chance to be
disabled. So this patch aim to fix this issue by adding pci_release call
in pci_remove, it will gurranty that all pci clean up will be done before
pci removal.
