Retire switchd and switchctl. While interesting they never managed to really get into a usable state. The OpenFlow API is mostly superseeded by P4 and so this is a bit of a dead end. OK akoshibe@ yasuoka@ deraadt@ kn@ patrick@ sthen@

switchd(8) will sometimes not save a copy of a packet needing forwarding even when a switch(4) instance requires it to supply it. Cases where this can happen are: if the copy of the packet recieved from the switch is too short (source/destination pairs can't be recovered), is non-unicast, or when switchd has to fall back to flooding traffic. Factor out the check for short packets, stopping before forwarding decisions are made if the full packet is needed by the switch. Set the packet buffer early for cases where it is needed otherwise. Also replace a few bzero's with memset's. Diff based on one by guenther@ OK phessler@

Learn remote switch flow tables properties to find out where to install the default table-miss flow for OpenFlow 1.3.5. This is enough to make switchd(8) to work with switch(4) and HP 3800 switch out-of-the-box. ok reyk@

Remove "workarounds" for the read and write path that were needed to handle /dev/switch connections that didn't quite behave like TCP connections (no support for writev, no partial reads).

Start reworking the "device" support in switchd: Once connected, a device is just an fd that is connected to a switch, either via TCP or via /dev/switch. Change the switchctl from "device add" to "connect" etc. This change is an intermediate step towards other changes, including the configuration grammar, so a few things will be left undocumented for now. switchctl(8) examples, switchctl connect /dev/switch0 switchctl connect /dev/switch0 forward-to 10.1.1.1 switchctl connect 127.0.0.1 switchctl connect 127.0.0.1 forward-to 10.1.1.1 switchctl disconnect /dev/switch0 Discussed with rzalamena@

Implement socket server code that properly handles async I/O, partial messages, multiple messages per buffer and important things like connection limits and file descriptor accounting. It works with TCP connections as well as switch(4). The ofrelay.c part replaces networking that was in ofp.c and will soon handle all socket connections of switchd. It is called "ofrelay" because it will be used as client, server, and forwarder. OK rzalamena@

Import switchd(8), a basic WIP OpenFlow implementation for OpenBSD. switchd consists of two parts: 1. switchd(8) and switchctl(8), an OpenFlow controller or "vswitch". 2. switch(4), an OpenFlow-aware kernel "bridge". This the 1st part, the driver will be imported later. The code will remain disabled for a while, but it helps development to have it in the tree. switchd currently supports partial OpenFlow 1.0, but the goal is to use OpenFlow 1.3.5 instead (switch(4) already does 1.3.5). For more background information see: http://www.openbsd.org/papers/bsdcan2016-switchd.pdf https://youtu.be/Cuo0qT-lqig With help from yasuoka@ goda@ Import discussed with deraadt@
