This can +be done when the module is loaded (specifying the name of the network interface +as a paramter - e.g. 'insmod ozwpan g_net_dev=go0') or can be bound after +loading using an ioctl call. See the ozappif.h file and the ioctls +OZ_IOCTL_ADD_BINDING and OZ_IOCTL_REMOVE_BINDING. + +The devices connect to the host use Wi-Fi Direct so a network card that supports +Wi-Fi direct is required. A recent version (0.8.x or later) version of the +wpa_supplicant can be used to setup the network interface to create a persistent +autonomous group (for older pre-WFD peripherals) or put in a listen state to +allow group negotiation to occur for more recent devices that support WFD. + +The protocol used over the network does not directly mimic the USB bus +transactions as this would be rather busy and inefficient. Instead the chapter 9 +requests are converted into a request/response pair of messages.

This implementation reflects those simple callers. Some day I'm sure + * we'll need to move to a more robust posting/callback mechanism. + * + * Transmit calls pass in kernel virtual addresses and block copying this into + * the socket's tx buffers via a usual blocking sendmsg. They'll block waiting + * for a failed socket to timeout. TX callers can also pass in a poniter to an + * 'int' which gets filled with an errno off the wire in response to the + * message they send. + * + * Handlers for unsolicited messages are registered. Each socket has a page + * that incoming data is copied into. First the header, then the data. + * Handlers are called from only one thread with a reference to this per-socket + * page. This page is destroyed after the handler call, so it can't be + * referenced beyond the call. Handlers may block but are discouraged from + * doing so. + * + * Any framing errors (bad magic, large payload lengths) close a connection. + * + * Our sock_container holds the state we associate with a socket. It's current + * framing state is held there as well as the refcounting we do around when it + * is safe to tear down the socket. The socket is only finally torn down from + * the container when the container loses all of its references -- so as long + * as you hold a ref on the container you can trust that the socket is valid + * for use with kernel socket APIs. + * + * Connections are initiated between a pair of nodes when the node with the + * higher node number gets a heartbeat callback which indicates that the lower + * numbered node has started heartbeating.
