I managed to finally get time to look into my esp32. I had to make 2 small changes to get things to compile, but it seems to do something now.
I do have issues starting monitor mode though:

esp32>  monitor start
Starting Monitor Mode...
[422.798838] I (423115) WIFI_CTL: Switching to MONITOR MODE (Ch 6)
[423.798986] I (424116) WiFi_Monitor: Initializing WiFi monitor mode on channel 6
[423.799417] E (424116) wifi_init: Failed to init, WiFi is initialized by esp_wifi_init
[423.810069] E (424127) WiFi_Monitor: WiFi init failed: ESP_ERR_INVALID_STATE
[423.810418] E (424127) WIFI_CTL: Failed to init monitor mode

this fails even when selecting other channels... (I note I did run wifi connect to my network first).
