@Stormgren My azonenberg/latentpacket repo has all of the networking stuff but yeah I probably need to update the high level project docs.
The high level goal is a layer 2 (to start), possibly with some layer 3 functionality in the future, switch that's simple, no frills, and fast.
I don't need support for 30 different kinds of multicast routing and DECnet and AX.25 and IPoAC.
Just give me a basic, 1990s style fixed function CAM ASIC style, switch with as few features and as little attack surface as possible, but also modern 10/25G interface support and good power efficiency.
So the vision is a switch with a dedicated 1000baseT SSH management interface and RS232 console port connected to the management CPU, while all switch fabric ports are completely independent of management and cannot talk to the management engine (there will be no "slow path", the CPU cannot see traffic going to/from switch ports).
I don't need a lot of bells and whistles. Just port based VLANs, 802.1q, ability to force ports to specific speed and maybe duplex states, access to diagnostics like performance counters and error rates, and probably eventually some kind of port mirror/capture capability.
