This is for SDK 2.9.2. In enet_driver.c there are a number of "#ifdef FEATURE_ENET_WAKEUP_IRQS". In S32K148_features.h it is #define'ed as FEATURE_ENET_WAKE_IRQS...
It could be intended as a different "#define" (there is a reference to FEATURE_ENET_WAKE_IRQS too in enet_driver.c) but in this case the other #define is missing (and other ENET IRQ features use a single such #define).
I thought so too at the beginning - but then I compared with other #define's such as FEATURE_ENET_RX_IRQS (and others) and there it uses only one #define for both flag and value... Even if what you suggest was true - the feature flag should be defined as (as 1 or as 0) - other similar feature flags in that file are defined so.
