Function netstack3_ip::device::add_ip_addr_subnet_with_config

pub fn add_ip_addr_subnet_with_config<I: IpDeviceIpExt, BC: IpDeviceBindingsContext<I, CC::DeviceId>, CC: IpDeviceStateContext<I, BC> + GmpHandler<I, BC> + DadHandler<I, BC>>(
    core_ctx: &mut CC,
    bindings_ctx: &mut BC,
    device_id: &CC::DeviceId,
    addr_sub: AddrSubnet<I::Addr, I::AssignedWitness>,
    addr_config: I::AddressConfig<BC::Instant>,
    _device_config: &I::Configuration,
) -> Result<CC::AddressId, ExistsError>

Adds addr_sub to device_id with configuration addr_config.

_device_config is not used but required to make sure that the caller is currently holding a a reference to the IP device’s IP configuration as a way to prove that caller has synchronized this operation with other accesses to the IP device configuration.
