Rather than using linuxapp and bsdapp everywhere, we can change things to
use the, more readable, terms "linux" and "freebsd" in our build configs.
Rather than renaming the configs we can just duplicate the existing ones
with the new names using symlinks, and use the new names exclusively
internally. ["make showconfigs" also only shows the new names to keep the
list short] The result is that backward compatibility is kept fully but any
new builds or development can be done using the newer names, i.e. both
"make config T=x86_64-native-linuxapp-gcc" and "T=x86_64-native-linux-gcc"
work.

Previously, it was possible to limit maximum amount of memory
allowed for allocation by creating validator callbacks. Although a
powerful tool, it's a bit of a hassle and requires modifying the
application for it to work with DPDK example applications.
Fix this by adding a new parameter "--socket-limit", with syntax
similar to "--socket-mem", which would set per-socket memory
allocation limits, and set up a default validator callback to deny
all allocations above the limit.
This option is incompatible with legacy mode, as validator callbacks
are not supported there.

We remove xen-specific code in EAL, including the option --xen-dom0,
memory initialization code, compiling dependency, etc.
Related documents are removed or updated, and bump the eal library
version.

DPDK has support for both sw and hw mempool and
currently user is limited to use ring_mp_mc pool.
In case user want to use other pool handle,
need to update config RTE_MEMPOOL_OPS_DEFAULT, then
build and run with desired pool handle.
Introducing eal option to override default pool handle.
Now user can override the RTE_MEMPOOL_OPS_DEFAULT by passing
pool handle to eal `--mbuf-pool-ops-name=""`.

The coremask option in DPDK is difficult to use and we should be
promoting the use of the corelist (-l) option. The patch
adjusts the docs to use -l EAL option instead of the -c option.
The patch only changes the docs and not the code as the -c option
will continue to exist unless it is removed in the future. The -c
option should be kept to maintain backward compatibility.

This is a useful default for simple applications where the assignment
of lcores to CPUs doesn't matter. It's also useful for more complex
applications that automatically assign tasks to cores based on the
NUMA topology.

Since DPDK now has support for the in-tree uio_pci_generic driver,
update the GSG document to reference this module, and to use it
in preference to the igb_uio driver, which is DPDK-specific.

which contains the table of contents.
This is the first document from a set of documents.
