[dpdk-dev] [PATCH 1/2] app/test: Add ABI Version Testing functionality

Tue May 28 13:51:57 CEST 2019
This patchset adds ABI Version Testing functionality to the app/test
unit test framework, comprised of
1. The TEST_DPDK_ABI_VERSION_* and REISTER_TEST_ABI_VERSION macros to
register abi versions with infrastructure.
2. The MAP_ABI_SYMBOL_VERSION macro to remap symbols based on their ABI
Version.
3. The set_abi_version command, to switch between ABI Versions.
