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.
