Kernel: Add a LoopbackAdapter for talking to yourself via 127.0.0.1. Choosing adapter for transmit is done by adapter_for_route_to(IPv4Address). This is just hard-coded logic right now but can be expanded to support a proper routing table. Also start moving kernel networking code into Kernel/Net/. 2019-04-02 13:46:44 +00:00			`#pragma once`

Kernel: Add simple ARP routing layer This replaces the previous placeholder routing layer with a real one! It's still very primitive, doesn't deal with things like timeouts very well, and will probably need several more iterations to support more normal networking things. I haven't confirmed that this works with anything other than the QEMU user networking layer, but I suspect that's what nearly everybody is using at this point, so that's the important target to keep working. 2019-08-28 11:58:01 +00:00			`struct RoutingDecision`
