^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) * This supports simple USB network links that don't require any special
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) * framing or hardware control operations. The protocol used here is a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) * strict subset of CDC Ethernet, with three basic differences reflecting
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) * the goal that almost any hardware should run it:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) * - Minimal runtime control: one interface, no altsettings, and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) * no vendor or class specific control requests. If a device is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) * configured, it is allowed to exchange packets with the host.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) * Fancier models would mean not working on some hardware.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) * - Minimal manufacturing control: no IEEE "Organizationally
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) * Unique ID" required, or an EEPROMs to store one. Each host uses
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) * one random "locally assigned" Ethernet address instead, which can
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) * of course be overridden using standard tools like "ifconfig".
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) * (With 2^46 such addresses, same-net collisions are quite rare.)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) * - There is no additional framing data for USB. Packets are written
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) * exactly as in CDC Ethernet, starting with an Ethernet header and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) * terminated by a short packet. However, the host will never send a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) * zero length packet; some systems can't handle those robustly.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40) * Anything that can transmit and receive USB bulk packets can implement
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 41) * this protocol. That includes both smart peripherals and quite a lot
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 42) * of "host-to-host" USB cables (which embed two devices back-to-back).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 43) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 44) * Note that although Linux may use many of those host-to-host links
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 45) * with this "cdc_subset" framing, that doesn't mean there may not be a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 46) * better approach. Handling the "other end unplugs/replugs" scenario
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 47) * well tends to require chip-specific vendor requests. Also, Windows
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 48) * peers at the other end of host-to-host cables may expect their own
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 49) * framing to be used rather than this "cdc_subset" model.
