Both these macros, if disabled, cause the IP task to filter the packets instead of the network driver task (EMAC task) using network driver-specific filtering functions.
Are there any ways to configure the driver to filter these properly?
Which version of FreeRTOS+TCP are you using? If using the newer versions then there are 2 network interfaces for STM32 - newer version and legacy. Please confirm which one is used.
I believe you previously had the ipconfigETHERNET_DRIVER_FILTERS_FRAME_TYPES enabled and the ipconfigETHERNET_DRIVER_FILTERS_PACKETS disabled? If thats the case something is causing eConsiderFrameForProcessing to drop the packets, adding more debug logs or breakpoints could help isolate the issue.
