  As discussed on the dpdk-dev mailing list[1], we can make some easy
improvements in standardizing the naming of the various components in DPDK,
and their associated feature-enabled macros.

Following this patch, each library will have the name in format,
'librte_<name>.so', and the macro indicating that library is enabled in the
build will have the form 'RTE_LIB_<NAME>'.

Similarly, for libraries, the equivalent name formats and macros are:
'librte_<class>_<name>.so' and 'RTE_<CLASS>_<NAME>', where class is the
device type taken from the relevant driver subdirectory name, i.e. 'net',
'crypto' etc.

To avoid too many changes at once for end applications, the old macro names
will still be provided in the build in this release, but will be removed
subsequently.

Does this change the share object file names too, or only the macros?

It does indeed change the object name files, which is a little bit
concerning. However, the consensus based on the RFC seemed to be that the
benefit is likely worth the change. If we want, we can look to use symlinks
to the old names on install, but I think that just delays the pain since I
would expect few to actually change their build to the new names until the
old ones and the symlinks completely go away.

It is a backward incompatible change, so we need to provide symlinks,
right? On upgrade, programs linked to librte_old.so will fail to start.
Or was this targeted at 20.11 thus piggy-backing on the ABI change
which forces a re-link?

More of the latter, and the fact that changing the build system involved a
few library renames anyway for those using make. Since the ABI is changing
this release, and all the libs have a new major version number there is no
requirement for libs linked against an older version to work, and since
pkg-config should now be used for linking the actual names should not be
a concern.

That's the thinking anyway. :-)

Ok that makes sense, I wasn't sure if this series was targeted for
20.11 or for later. In that case,

Yes, if it doesn't make 20.11 we'll have to re-evaluate and be stricter
with the compatibility constraints. It might not be worth doing post-20.11.

+* build: The macros defined to indicate which DPDK libraries and drivers
