Some global variables can be eliminated, since they are not part of

I think `rte_rawdevs` can also be removed from an exposed symbol. In all
cases (at least for now), this is being accessed using an API (and no
macros). There should be no need for people to read this directly if
sufficient get_by_* APIs are available.
+1 to make it library internal.
But `rte_rawdevs` is both in public header and .map file, so it is part of
public API, we can't remove it without deprecation process.
And I want to leave the decision of removing an public symbol to library
maintainers.
Yes, I missed that part :)
I will fix it in next release by sending deprecation in this.
Wouldn't same be valid for rte_compressdevs as well?
`rte_compressdevs` is already removed, but if you mean `rte_cryptodevs` it has
same problem with `rte_rawdevs`, it is part of API.
Ah yes, my mistake.
I was thinking about rte_eventdevs and rte_cryptodevs (but, this symbol
is being used by a crypto/scheduler)
