There are two warnings in the VFIO section about limitations of VFIO and
limitations on who can bind/unbind devices. Since these don't actually
describe any unsafe conditions, and are more informational, we can
change these to notes. This also helps emphasise the other warnings in
the documents which flag genuine security concerns.

doc: consolidate VFIO content on Linux drivers page
Rather than having separate sections for VFIO and VFIO no-iommu mode, as
well as a separate section further down the document on troubleshooting
VFIO, we can consolidate all these as subsections into a primary VFIO
section. This section starts with the basics of VFIO use, then covers
no-iommu mode, before moving on to the more advanced topics such as
creating VFs and ending with the troubleshooting subsection.

The VFIO section of the page about Linux drivers was rather long and
unstructured. This can be improved by splitting it up into subsections,
to cover the specifics of memory limits and creating VFs. When moving
the various text notes into the relevant subsections, we can drop the
note about kernels earlier than 3.6, since DPDK no longer supports
kernels that old.

While the details of VFIO and UIO may be of interest to some, most users
of the doc are likely primarily interested in how to bind their devices
to the kernel driver and then move on to running the app. Therefore, the
most important part of the "Linux Drivers" section of the GSG is the
subsection on "Binding and Unbinding", so put that first.

The GSG has a note warning that use of UIO is inherently unsafe due to

"warning" and moving it to the top of the UIO subsection makes this a

The "Linux Drivers" section of the GSG already notes that, for use of

Therefore, there is no need to duplicate this information in the
"additional functionality" section. Also the kernel configuration
options documented in the section are enabled as standard on all common
distro kernels, so the information should not be needed in a GSG doc.

Not all directories were given in the GSG document, but many of those

"kernel" as the only undocumented directories, so add them in too for
completeness.

it is not guaranteed to always be.

doc: merge Linux requirements for applications build
When building end-applications linked with DPDK, the only additional
tool needed is pkg-config/pkgconf. However, the standard development
tools meta-packages on most distro's include this as standard, meaning
it does not really require its own section. The one outlier in the
existing text is "alpine" where it is not present when using "libc-dev"
target. However, changing "gcc" and "libc-dev" to "alpine-sdk"
metapackage aligns alpine with the other distros in this regard.
