Add support coex for ESP32C6

[TuEmb]

Hi @bugadani, @bjoernQ,

I created a PR to support Coex for ESP32C6. Those changes were discussed from #300

• Enabled COEX feature and created new COEX example for ESP32C6.
• Added big-heap when run COEX mode.
• Calling G_COEX_FUNCS in COEX mode
• Increase tx_queue_size to be greater than rx_queue_size

I'm not sure if we should change the default just to get rid of some warnings

We probably will revise the defaults at some point (e.g. check #233 (review) ) and when we do it, we also need to update the documentation about it

Especially since this is user-configurable

[TuEmb]

I think we can keep default value as #233. We can change when using because it user-configurable

[bjoernQ]

Works great! Thanks a lot for this

I'm not sure about changing the defaults and this needs a cargo fmt - otherwise I'm fine with merging this.

I tested on all supported targets and nothing broke 👍

Be sure to remove esp32c6 from this list when you rebase :https://github.com/esp-rs/esp-wifi/blob/7632e74285a70e155a10e8dee4b6dde50d78394f/esp-wifi/build.rs#L22

I'd really love to get this merged.

Unfortunately reviewing this is a bit difficult since there is a merge commit in bc3017a (i.e. +3,083 −9,239) - would you mind removing that commit and rebase on main instead?

It also seems that in esp-wifi/lib.rs the default of tx_queue_size: usize, is still changed to 10

it also seems it stopped working for me 😢

Ah - it works when using the big-heap feature. Maybe something to address in src\lib.rs when defining the DEFAULT_HEAP_SIZE

Got it to work by reverting bc3017a, doing what Scott said in #327 (comment) , reverting the change to the default of tx_queue_size and using big-heap

@TuEmb do you want to do these changes or should I take over if you don't have the time to do this (certainly keeping your original commit)

[TuEmb]

Thanks for reviewing @bjoernQ ,

Let me do these changes soon 🤝

[bjoernQ]

LGTM - Thanks for your contribution!

[bjoernQ]

You just need to fix the formatting issue then we can get this in
