[PATCH 1/2] doc: remove reference to device selection option

[PATCH 1/2] doc: remove reference to device selection option

[David Marchand]

--use-device was replaced with -a / --vdev options in v1.6
with commit cac6d08c8bde ("devargs: replace --use-device option by
--pci-whitelist and --vdev").

It was reintroduced in the doc in v1.8 when the rst documentation
was imported in .rst format.

Fixes: 1ab07743b21b ("doc: getting started guide for linux")
Fixes: dacdbfa45752 ("doc: getting started guide for freebsd")

[PATCH 2/2] doc: use common description of EAL parameters

[David Marchand]

Rather than have a subset of the EAL parameters described in the sample
apps documentation, prefer referring to the full list.

-A large number of options can be given to the EAL when running an
-application. A full list of options can be got by passing `--help` to a
-DPDK application. Some of the EAL options for FreeBSD are as follows:
-
-*   ``-l CORELIST``:
-    A comma-separated list of the cores, or ranges of cores to run on.
-    For example, ``-l 0,1,4-6`` will run on cores 0, 1, 4, 5 and 6.
-    Note that core numbering can change between platforms and should be determined beforehand.
-
-*   ``-b <domain:bus:devid.func>``:
-    Blocklisting of ports; prevent EAL from using specified PCI device
-    (multiple ``-b`` options are allowed).
-
-*   ``-v``:
-    Display version information on startup.
-
-*   ``-m MB``:
-    Memory to allocate from hugepages, regardless of processor socket.
-
-Other options, specific to Linux and are not supported under FreeBSD are as follows:
-
-*   ``socket-mem``:
-    Memory to allocate from hugepages on specific sockets.
-
-*   ``--huge-dir``:
-    The directory where hugetlbfs is mounted.

-*   ``--mbuf-pool-ops-name``:
-    Pool ops name for mbuf to use.

-
-* ``-d``:

-  The application should use this option to load the PMDs

-  Use VMware TSC map instead of native RDTSC.
-
-* ``--base-virtaddr``:
-  Specify base virtual address.
-
-* ``--vfio-intr``:
-  Specify interrupt type to be used by VFIO (has no effect if VFIO is not used).

Those are some really, really old release versions! This issue has been
around a very long time, it seems!
