Move USB network drivers to drivers/net/usb.
It is preferable to group drivers by usage (net, scsi, ATA, ...) than by bus. When reviewing drivers, the [PCI|USB|PCMCIA|...] maintainer is probably less qualified on networking issues than a networking maintainer. Also, from a practical standpoint, chips often appear on multiple buses, which is why we do not put drivers into drivers/pci/net.

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