How to wake_up the wait_queue of a socket?

[Peter Teoh]

essentially, when the packet arrive, it will be assigned to the correct
process based on IP address + port matching, and then the corresponding
process's blocked scheduling status will be changed to continue execution,
so that when the scheduler next selection of runnable process will pick him
out for continue execution.   The process will then pick his data up from
the network queue.

hope I have not made any mistake in my logic?
