A few remaining Clippy suggestions.

1. Don't name structs with the name of the module:

warning: item name ends with its containing module's name. You can always call `BaseConfig` as `config::Base`
  --> src/config.rs:19:1
   |
19 | / pub struct BaseConfig {
20 | |     pub frontends: HashMap<String, FrontendConfig>,
21 | |     pub backends: HashMap<String, BackendPool>,
22 | |     pub stats: Stats,
23 | |     pub passthrough: Option<Passthrough>,
24 | | }
   | |_^
   |

   = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#module_name_repetitions

and

warning: item name starts with its containing module's name
  --> src/stats.rs:24:1
   |
24 | / pub struct StatsApi {
25 | |     stats: Arc<RwLock<Stats>>,
26 | | }
   | |_^
   |

2. If your enum is called ReadError all fields inside are errors, so it is kind of redundant to have Error in the enum fields.

warning: All variants have the same postfix: `Error`
  --> src/config.rs:57:1
   |
57 | / pub enum ReadError {
58 | |     IOError(IOError),
59 | |     ParseError(Vec<toml::de::Error>),
60 | |     DecodeError(toml::de::Error),
61 | | }
   | |_^
   |
   = note: `-W clippy::pub-enum-variant-names` implied by `-W clippy::pedantic`
   = help: remove the postfixes and use full paths to the variants instead of glob imports
   = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#pub_enum_variant_names

3. it seems that tokio::prelude is unused here:

warning: unused import: `tokio::prelude`
  --> src/proxy/mod.rs:11:5
   |
11 | use tokio::prelude::*;
   |     ^^^^^^^^^^^^^^
   |
   = note: `#[warn(unused_imports)]` on by default

What do you think? I used cargo-outdated to track outdated dependencies. All tests and build seem to pass.

I would squash this to clean all repeated commits as our sources got different from my experimentations on my on source.

Since we're now sending out with IP_HDRINCL set on raw socket the kernel will perform the checksum calculation on the ip header anyway. So there's no need to do it twice

• configure workers to listen and send on independent sockets
• setup listening L2 socket to fanout for load balancing
• send on L3 socket
• remove channels for passing packets
• remove arp managing

Does DSR work across servers in different datacentres?

I have got the standard proxy working but cant get the config working for DSR and cant see where I'm going wrong from the instructions. Is there a log anywhere I could check?

The interface is listening with no errors, but I cant complete a TCP connection with the server behind it.

I set up the balancers as per the instructions below, is there anythign I could be missing?

Thank You for any help
