In some cases, for a custom build a user may want to override those settings via CFLAGS, so we need to ensure that the definitions do not override the user-provided values. Bruce Richardson (3): config: remove explicit undefinition of unset values config: allow overriding some build defaults doc: add notes on overriding extra config values config/rte_config.h | 122 +++++++++++++++++++--- doc/guides/linux_gsg/build_dpdk.rst | 8 ++ doc/guides/prog_guide/build-sdk-meson.rst | 8 ++ 3 files changed, 121 insertions(+), 17 deletions(-) -- 2.25.1
