This moves the netdev/netlink namespace out of drivers and into their own packages. Also, defines netdev and netlink as L3/L4 and L2 OSI layers, respectively. Move some L3 functionality from netlink to netdev (GetIPAddr). For netlink, add ConnectParams for NetConnect to pass in L2 connection parameters (ssid, pass, auth_type, etc). Also adds connection mode (STA, AP, etc). For netlink, add SendEth and RecvEthFunc funcs to handle L2 send/recv of Ethernet pkts.

// This example listens on port :8080 for client connections. Bytes
|
|
// received from the client are echo'ed back to the client. Multiple
|
|
// clients can connect as the same time, each consuming a client socket,
|
|
// and being serviced by it's own go func.
|
|
//
|
|
// Example test using nc as client to copy file:
|
|
//
|
|
// $ nc 10.0.0.2 8080 <file >copy ; cmp file copy
