This patch can make above such checking in a common way in rte_ethdev

This patch assumes that all PMDs in 18.05-rc2 have already
converted to offload API defined in 17.11 . It also assumes
that all PMDs can return correct offloading capabilities

defined in 17.11 to avoid upper application broken due to offload
API change.
PMD can use the info that input [rt]xconf->offloads only carry

app/testpmd: fix empty list of RSS queues for flow

Since the commit referenced below, specifying a RSS action without any
queues (e.g. "actions rss queues end / end") does not override the default
set automatically generated by testpmd.

In short, one cannot instantiate a RSS action with 0 target queues anymore
in order to determine how PMDs react (hint: this is currently undocumented
so they may reject it, however ideally they should interpret it as a
default setting like for other fields where empty values stand for
"defaults".)

The function pthread_create() expects void *(*func) (void *)

void (*func) (void *), so now gcc 8.1 warns that the cast is

the declaration of lthread_func_t from returning a void to
