20789d4dfd doc: improve Mellanox bifurcated model description
In the howto guide about flow bifurcation, the Mellanox case
(which does not require specific details) was missing in the landscape.

In the Linux drivers guide, it was not clear that the flow bifurcation
is performed in the NIC hardware.

References to flow isolated mode are also inserted in those contexts.

2eb7c526b9 doc: clarify IOMMU disabling for uio_pci_generic
If the devices used for DPDK are bound to the "uio_pci_generic" kernel
module, the IOMMU should be disabled in order not to break the IO
transmission because of the virtual / physical address mapping.

The patch clarifies the IOMMU configurations on both x86_64 and arm64
systems.

ccf5fd6045 doc: warn about UIO not working with UEFI secure boot
Added notes to the documentation warning that if UEFI secure boot
is enabled the Linux kernel may disallow the use of UIO on the
system, and a suggested workaround of using the vfio-pci kernel
module instead of igb_uio or uio_pci_generic.

0db52e6694 doc: move kernel drivers to a new chapter
The UIO and VFIO sections should not be part of
the "Compiling the DPDK Target from Source" chapter,
as it is PMD specific and not true for all PMDs.

Instead, moving those sections to a new chapter
which include all kernel drivers being used along with
the different PMDs.
