Fix compilation errors on Centos 7.4 when CONFIG_RTE_KNI_KMOD_ETHTOOL
is set to 'y'.
Centos 7.4 needs HAVE_NDO_BRIDGE_GETLINK_FILTER_MASK_VLAN_FILL:
igb_main.c: In function ‘igb_ndo_bridge_getlink’:
igb_main.c:2289:2: error: too few arguments to function
‘ndo_dflt_bridge_getlink’
return ndo_dflt_bridge_getlink(skb, pid, seq, dev, mode, 0, 0, nlflags);
^
Centos 7.4 needs HAVE_VF_VLAN_PROTO and needs to redefine
ndo_set_vf_vlan to .extended.ndo_set_vf_vlan:
igb_main.c:2318:2: error: unknown field ‘ndo_set_vf_vlan’ specified
in initializer
.ndo_set_vf_vlan = igb_ndo_set_vf_vlan,

rx_q fifo can only be released by kernel thread. There may be
mbuf leaks in rx_q because kernel threads are randomly stopped.
When the kni is released and netdev is unregisterd, convert the
physical address mbufs in rx_q to the virtual address in free_q.
By the way, alloc_q can be processed together to speed up the
release rate in userspace.
In my test, it is improved from 300-500ms with a mempool that has
131072 mbufs to 10ms(regardless of the specifications).

When cross-compiling, if no kernel_dir was specified, then the kernel
modules were still being compiled for the build machine. Fix this by
only building modules on cross-compile when we have a kernel_dir value
set. Print out a message indicating why we are skipping kernel
compilation, and in case that the headers for kernel compile are not
found, print a warning instead of erroring out.

With the legacy build system MODULE_CFLAGS can be set to pass compiler
flags specific for the kernel modules builds.
This is used currently by Ubuntu and Debian.
Set ccflags-y in the Kbuild to achieve the same result with Meson, and
to keep backward compatbility with older scripts.
Fixes regression in Ubuntu/Debian when the Kbuild is included in the
DKMS source package, as DKMS will pick it up silently by default if
present, causing the MODULE_CFLAGS to be ignored.

The meson.build files for building the kernel modules directory could
be improved now that it is extracted from the EAL. For example, no
global processing is necessary inside the kernel folder, just need to
subdir to the appropriate bsd or linux folder to do the actual work.
To avoid potential race conditions with the BSD module builds when
the kernel build system is creating the dev_if.h and other files,
we serialize the kernel module builds (all 2 of them!) by setting
up each module to depend on all the previous.

Starting from Linux v3.16 pci_is_bridge() is in linux/pci.h,
in previous versions it is in drivers/pci/pci.h which is private header.
Fix build error when calling pci_is_bridge by not calling/supporting
pci_is_bridge with kernel versions before 3.16.
