User-space networking stack API allows user-space daemon to provide TCP/IP stack implementation for NuttX network. Main use for this is to allow use and seamless integration of HW-provided TCP/IP stacks to NuttX. For example, user-space daemon can translate /dev/usrsock API requests to HW TCP/IP API requests while rest of the user-space can access standard socket API, with socket descriptors that can be used with NuttX system calls.

One problem with UDP communications is that, unlike TCP/IP, there is
|
|
no backlog of UDP packets. So if you are listening at the precise
|
|
moment that the UDP packet is sent, it will not be received. This
|
|
is not incompatible with the properties of UDP, but can result in
|
|
bad performance if packets are missed, time out, and are resent.
|
|
|
|
Some Ethernet controllers have built-in RAM and the drivers can
|
|
support retention of UDP packets in that RAM. If the drivers
|
|
supports such a capability, this option may be enabled to use it.
|
|
NOTE: If this option is enabled, the driver must support the
|
|
rxavail() method in the net_driver_s structure.
