The config/rte_config.h source code configuration is for exotic configuration
parameters that we don't want to expose to Meson.
The threshold between normal and exotic is not well defined. :-)
The bug report says that ethdev rx/tx callbacks cannot be disabled in
config/rte_config.h, where it is configurable. This is not correct. They can be
disabled in config/rte_config.h, so there is no bug; the bug reporter just
didn't know how to do it.
Although I personally prefer #if over #ifdef, it would be a huge patch series
to replace all occurrences of #ifdef XYZ with #if XYZ. (2800+ LOC containing
'#ifdef': grep -r '#ifdef' | grep -v '__cplusplus' | wc)
