Network Core Helpers
Overview
The network subsystem contains two functions for sending and receiving
data from the network. The net_recv_data() is typically used by network
device driver when the received network data needs to be pushed up in the
network stack for further processing. All the data is received via a network
interface which is typically created by the device driver.
For sending, the net_send_data() can be used. Typically applications do not
call this function directly as there is the BSD Sockets API
for sending and receiving network data.
