[dpdk-dev] [PATCH v3 01/12] common/dpaax: move internal symbols into INTERNAL section

[Thomas Monjalon]

Adding a bit more definitions to better understand.

A "stable" library exports at least one symbol in the current stable ABI.
Its soname is suffixed with the current ABI version.
If the library exports no symbol in the current ABI, but has a symbol in
the next ABI, the soname is suffixed also with the current ABI version.

A "pure experimental" library exports only experimental symbols.
Its soname is suffixed with 0. and the stable ABI version.

A "pure internal" library has only internal symbols,
or no exported symbols at all, like in most PMDs.
Its soname is suffixed with the current ABI version.

An "experimental & internal" library exports experimental and internal
symbols, but none in current or next stable ABI.
We don't have such case yet.

I think the original intent was to use the suffix 0.x for libs
which export no stable ABI. But it is inconsistent currently.

Please read the options below, and give your opinion.
Thanks
