uwb: Remove the WLP subsystem and drivers

The only Wimedia LLC Protocol (WLP) hardware was an Intel i1480 chip
with a beta release of firmware that was never commercially available as
a product.  This hardware and firmware is no longer available as Intel
sold their UWB/WLP IP.  I also see little prospect of other WLP
capable hardware ever being available.

- * This implements a very simple network driver for the WLP USB
- * device that is associated to a UWB (Ultra Wide Band) host.
- *
- * This is seen as an interface of a composite device. Once the UWB
- * host has an association to another WLP capable device, the
- * networking interface (aka WLP) can start to send packets back and
- * forth.
- *
- * Limitations:
- *
- *  - Hand cranked; can't ifup the interface until there is an association
- *
- *  - BW allocation very simplistic [see i1480u_mas_set() and callees].
- *

- *     i1480u_driver_{exit,init}(): initialization of the driver.

- *                     matching 'i1480u_id_table' is connected.
- *
- *                     This allocs a netdev instance, inits with

- *
- * i1480u's RX handling is simple. i1480u will send the received
- * network packets broken up in fragments; 1 to N fragments make a
- * packet, we assemble them together and deliver the packet with netif_rx().
- *
- * Beacuse each USB transfer is a *single* fragment (except when the
- * transfer contains a first fragment), each URB called thus
- * back contains one or two fragments. So we queue N URBs, each with its own
- * fragment buffer. When a URB is done, we process it (adding to the
- * current skb from the fragment buffer until complete). Once
- * processed, we requeue the URB. There is always a bunch of URBs
- * ready to take data, so the intergap should be minimal.
- *
- * An URB's transfer buffer is the data field of a socket buffer. This
- * reduces copying as data can be passed directly to network layer. If a
- * complete packet or 1st fragment is received the URB's transfer buffer is
- * taken away from it and used to send data to the network layer. In this
- * case a new transfer buffer is allocated to the URB before being requeued.
- * If a "NEXT" or "LAST" fragment is received, the fragment contents is
- * appended to the RX packet under construction and the transfer buffer
- * is reused. To be able to use this buffer to assemble complete packets
- * we set each buffer's size to that of the MAX ethernet packet that can
- * be received. There is thus room for improvement in memory usage.
- *
- * When the max tx fragment size increases, we should be able to read
- * data into the skbs directly with very simple code.
- *
- * ROADMAP:
- *
- *   ENTRY POINTS:
- *
- *     i1480u_rx_setup(): setup RX context [from i1480u_open()]
- *
- *     i1480u_rx_release(): release RX context [from i1480u_stop()]
- *
- *     i1480u_rx_cb(): called when the RX USB URB receives a
- *                     packet. It removes the header and pushes it up
- *                     the Linux netdev stack with netif_rx().
- *
- *       i1480u_rx_buffer()
- *         i1480u_drop() and i1480u_fix()

- * Called when an RX URB has finished receiving or has found some kind

- * LIMITATIONS:
- *
- *  - We read USB-transfers, each transfer contains a SINGLE fragment
- *    (can contain a complete packet, or a 1st, next, or last fragment
- *    of a packet).
- *    Looks like a transfer can contain more than one fragment (07/18/06)
- *
- *  - Each transfer buffer is the size of the maximum packet size (minus
- *    headroom), i1480u_MAX_PKT_SIZE - 2
- *
- *  - We always read the full USB-transfer, no partials.
- *
- *  - Each transfer is read directly into a skb. This skb will be used to
- *    send data to the upper layers if it is the first fragment or a complete
- *    packet. In the other cases the data will be copied from the skb to
- *    another skb that is being prepared for the upper layers from a prev
- *    first fragment.
- *
- * It is simply too much of a pain. Gosh, there should be a unified
- * SG infrastructure for *everything* [so that I could declare a SG
- * buffer, pass it to USB for receiving, append some space to it if
- * I wish, receive more until I have the whole chunk, adapt
- * pointers on each fragment to remove hardware headers and then
- * attach that to an skbuff and netif_rx()].

- *     i1480u_tx_release(): called by i1480u_disconnect() to release
- *                          pending tx contexts.
- *
- *     i1480u_tx_cb(): callback for TX contexts (USB URBs)
- *       i1480u_tx_destroy():
- *
- *     i1480u_tx_timeout(): called for timeout handling from the
- *                          network stack.
- *
- *     i1480u_hard_start_xmit(): called for transmitting an skb from
- *                               the network stack. Will interact with WLP
- *                               substack to verify and prepare frame.
- *       i1480u_xmit_frame(): actual transmission on hardware
- *
- *         i1480u_tx_create()	    Creates TX context
- *            i1480u_tx_create_1()    For packets in 1 fragment
- *            i1480u_tx_create_n()    For packets in >1 fragments
- *
- * TODO:

- * We need to be able to map ethernet addresses to device addresses
- * and back because there is not explicit relationship between the eth
- * addresses used in the ETH frames and the device addresses (no, it
- * would not have been simpler to force as ETH address the MBOA MAC
- * address...no, not at all :).
- *
- * A device has one MBOA MAC address and one device address. It is possible
- * for a device to have more than one virtual MAC address (although a
- * virtual address can be the same as the MBOA MAC address). The device
- * address is guaranteed to be unique among the devices in the extended
- * beacon group (see ECMA 17.1.1). We thus use the device address as index
- * to this cache. We do allow searching based on virtual address as this
- * is how Ethernet frames will be addressed.
- *
- * We need to support virtual EUI-48. Although, right now the virtual
- * EUI-48 will always be the same as the MAC SAP address. The EDA cache
- * entry thus contains a MAC SAP address as well as the virtual address
- * (used to map the network stack address to a neighbor). When we move
- * to support more than one virtual MAC on a host then this organization
- * will have to change. Perhaps a neighbor has a list of WSSs, each with a
- * tag and virtual EUI-48.
- *
- * On data transmission
- * it is used to determine if the neighbor is connected and what WSS it
- * belongs to. With this we know what tag to add to the WLP frame. Storing
- * the WSS in the EDA cache may be overkill because we only support one
- * WSS. Hopefully we will support more than one WSS at some point.
- * On data reception it is used to determine the WSS based on
- * the tag and address of the transmitting neighbor.

- * Verify frame from network stack, prepare for further transmission

- *         over the entire transmission.
- *         If it is a unicast the WSS connection should already be established

- * @returns: 0 on success no tx : WLP header successfully applied to skb buffer,
- *                                calling function can proceed with tx
- *           1 on success with tx : WLP will take over transmission of this
- *                                  frame
- *           <0 on error
- *
- * The network stack (WLP client) is attempting to transmit a frame. We can
- * only transmit data if a local WSS is at least active (connection will be
- * done here if this is a broadcast frame and neighbor also has the WSS
- * active).
- *
- * The frame can be either broadcast or unicast. Broadcast in a WSS is
- * supported via multicast, but we don't support multicast yet (until
- * devices start to support MAB IEs). If a broadcast frame needs to be
- * transmitted it is treated as a unicast frame to each neighbor. In this
- * case the WLP takes over transmission of the skb and returns 1
- * to the caller to indicate so. Also, in this case, if a neighbor has the
- * same WSS activated but is not connected then the WSS connection will be
- * done at this time. The neighbor's virtual address will be learned at
- * this time.
- *
- * The destination address in a unicast frame is the virtual address of the
- * neighbor. This address only becomes known when a WSS connection is
- * established. We thus rely on a broadcast frame to trigger the setup of
- * WSS connections to all neighbors before we are able to send unicast
- * frames to them. This seems reasonable as IP would usually use ARP first
- * before any unicast frames are sent.
- *
- * If we are already connected to the neighbor (neighbor's virtual address
- * is known) we just prepare the WLP header and the caller will continue to
- * send the frame.
- *
- * A failure in this function usually indicates something that cannot be
- * fixed automatically. So, if this function fails (@return < 0) the calling
- * function should not retry to send the frame as it will very likely keep
- * failing.
