5.1 compatability?

[alex-red]

Hey, thanks for this!

I'm playing around with a esp32-c6 which requires the esp-idf 5.1 which has a lot of breaking changes, particularily with dhcps_set_option_info. I thought I would pick your brain to see if you had any ideas how I could adapt this to work with 5.1.

Error:

My setup:

esphome:
  name: esp32-c6-a
  friendly_name: esp32-c6-a
  includes:
    - nat-ap.h
    
esp32:
  board: esp32-c6-devkitc-1
  variant: esp32c6
  framework:
    type: esp-idf
    version: 5.1.0
    platform_version: https://github.com/stintel/platform-espressif32#esp32-c6-test
    sdkconfig_options:
      CONFIG_COMPILER_OPTIMIZATION_SIZE: y
      CONFIG_LWIP_IP_FORWARD: y
      CONFIG_LWIP_IPV4_NAPT: y

I think this is how they want us to use it now: https://docs.espressif.com/projects/esp-faq/en/latest/software-framework/wifi.html#lwip-how-to-configure-the-option-contents-of-dhcp-server-in-esp-idf but I couldn't get it to work.

The 'incomplete type' seems to indicate that some include is missing.... but I haven't tried 5.x myself. Many esphome modules seem to not be compatible with version 5 yet.
