Deserialization using serde_yaml seems to be failing when it involves a nested struct

[divn123]

Deserialization using serde_yaml seems to be failing when it involves a nested struct like below. Is this a bug or am I missing something here?
Cargo.toml

[package]
name = "random"
version = "0.1.0"
edition = "2021"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
serde_yaml = "0.9.27"
serde = { version = "1.0.123", features = ["derive"] }

Rust code

use serde::{Deserialize, Serialize};
use std::net::SocketAddr;

#[derive(Debug, Clone, Deserialize, Serialize)]
#[serde(rename_all = "kebab-case")]
struct Config<A> {
    sync: Option<bool>,
    #[serde(flatten)]
    addition: A,
}

#[derive(Debug, Clone, Deserialize, Serialize)]
#[serde(rename_all = "kebab-case")]
struct MyConfig {
    pub netconfig: Option<NetworkConfig>,
}

#[derive(Debug, Clone, Serialize, Deserialize)]
#[serde(rename_all = "kebab-case")]
//#[serde(tag = "type", content = "value")]
pub enum NetworkConfig {
    Ethernet(SocketAddr),
}

// #[tokio::main]
fn main() {
    let config_str = r#"
netconfig: !ethernet 192.168.2.10:1234
"#;

    let value: serde_yaml::Value = serde_yaml::from_str(config_str).unwrap();
    println!("file-to-value \n {:?}", value);
    let config: MyConfig = serde_yaml::from_value(value.clone()).unwrap();
    println!("value-to-struct\n {:?}", config);
    // This below line fails
    let config: Config<MyConfig> = serde_yaml::from_value(value).unwrap();
    println!("value-to-struct\n {:?}", config);
}

Output with error
