net/udp: Remove net stack dependency from CONFIG_NET_BROADCAST This change allows us to use CONFIG_NET_BROADCAST without network stack. (i.e. usrsock application can use broadcast) Signed-off-by: Masayuki Ishikawa <Masayuki.Ishikawa@jp.sony.com> Approved-by: Gregory Nutt <gnutt@nuttx.org>

Write buffers allows buffering of ongoing UDP/IP packets, providing

for higher performance, streamed output.

You might want to disable UDP/IP write buffering on a highly memory
|
|
memory constrained system where there are no performance issues.

These tiny nodes are used as "containers" to support queuing of
|
|
UDP write buffers. This setting will limit the number of UDP write
|
|
operations that can be "in-flight" at any give time. So a good
|
|
choice for this value would be the same as the maximum number of

UDP connections.

This option will force debug output from UDP write buffer logic,
|
|
even without network debug output. This is not normally something
|

that would want to do but is convenient if you are debugging the
|
|
write buffer logic and do not want to get overloaded with other

network-related debug output.

Dump the contents of the write buffers. You do not want to do this

detail.

Enable building of UDP read-ahead notifier logic that will execute a

worker function on the high priority work queue when read-ahead data
|
|
is available. This is is a general purpose notifier, but was
|
|
developed specifically to support poll() logic where the poll must
|
|
wait for read-ahead data to become available.
