* kvargs: The function ``rte_kvargs_process`` will get a new parameter
for returning key match count. It will ease handling of no-match case.
* eal: To be more inclusive in choice of naming, the DPDK project
will replace uses of master/slave in the API's and command line arguments.
References to master/slave in relation to lcore will be renamed
to initial/worker. The function ``rte_get_master_lcore()``
will be renamed to ``rte_get_initial_lcore()``.
For the 20.11 release, both names will be present and the
old function will be marked with the deprecated tag.
The old function will be removed in a future version.
The iterator for worker lcores will also change:
``RTE_LCORE_FOREACH_SLAVE`` will be replaced with
``RTE_LCORE_FOREACH_WORKER``.
The ``master-lcore`` argument to testpmd will be replaced
with ``initial-lcore``. The old ``master-lcore`` argument
will produce a runtime notification in 20.11 release, and
be removed completely in a future release.
* eal: The function ``rte_eal_remote_launch`` will return new error codes
after read or write error on the pipe, instead of calling ``rte_panic``.
