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.

- * Prolific PL-2301/PL-2302 driver ... http://www.prolifictech.com
- *
- * The protocol and handshaking used here should be bug-compatible
- * with the Linux 2.2 "plusb" driver, by Deti Fliegl.
- *
- * HEADS UP: this handshaking isn't all that robust. This driver
- * gets confused easily if you unplug one end of the cable then
- * try to connect it again; you'll need to restart both ends. The
- * "naplink" software (used by some PlayStation/2 deveopers) does
- * the handshaking much better! Also, sometimes this hardware
- * seems to get wedged under load. Prolific docs are weak, and
- * don't identify differences between PL2301 and PL2302, much less
- * anything to explain the different PL2302 versions observed.
