Can't flash MDF examples to ESP32 - mesh_chain_layer_t error

[karunt]

I'm trying to flash and monitor the mwifi/router example to my ESP32 chip, but the compilation process throws the following error:

In file included from C:/Users/Karun/ESP/esp-mdf/components/mwifi/mwifi.c:15:

Similar thing happens when trying to flash the mconfig example. Any idea how to resolve this? I'm out of ideas.
