Squashed commit of the following:
net/udp: Address most of the issues with UDP write buffering. There is a remaining issue with handling one network going down in a multi-network environment. None of this has been test but it is certainly ready for test. Hence, the feature is marked EXPERIMENTAL.
net/udp: Some baby steps toward a corrected write buffering design.
net/udp: Remove pesky write buffer macros.
Eliminate trailing space at the end of lines.
net/udp: A little more UDP write buffering logic. Still at least on big gaping hole in the design.
net/udp: Undefined CONFIG_NET_SENDTO_TIMEOUT.
net/udp: Crude, naive port of the TCP write buffering logic into UDP. This commit is certainly non-functional and is simply a starting point for the implementatin of UDP write buffering.
net/udp: Rename udp/udp_psock_sendto.c udp/udp_psock_sendto_unbuffered.c.

* Name: net_setup
|
|
*
|
|
* Description:
|
|
* This is called from the OS initialization logic at power-up reset in
|
|
* order to configure networking data structures. This is called prior
|
|
* to platform-specific driver initialization so that the networking
|
|
* subsystem is prepared to deal with network driver initialization
|
|
* actions.
|
|
*
|
|
* Actions performed in this initialization phase assume that base OS
|
|
* facilities such as semaphores are available but this logic cannot
|
|
* depend upon OS resources such as interrupts or timers which are not
|
|
* yet available.
|
|
*
|
|
* Input Parameters:
|
|
* None
|
|
*
|
|
* Returned Value:
|
|
* None
