Add user-space networking stack API (usrsock)
...
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.

While working with version 7.10 I discovered a problem in TCP stack that could be observed on high network load. Generally speaking, the problem is that RST flag is set in unnecessary case, in which between loss of some TCP packet and its proper retransmission, another packets had been successfully sent. The scenario is as follows: NuttX did not receive ACK for some sent packet, so it has been probably lost somewhere. But before its retransmission starts, NuttX is correctly issuing next TCP packets, with sequence numbers increasing properly. When the retransmission of previously lost packet finally succeeds, tcp_input receives the accumulated ACK value, which acknowledges also the packets sent in the meantime (i.e. between unsuccessful sending of lost packet and its proper retransmission). However, variable unackseq is still set to conn->isn + conn->sent, which is truth only if no further packets transmission occurred in the meantime. Because of incorrect (in such specific case) unackseq value, few lines further condition if (ackseq <= unackseq)is not met, and, as a result, we are going to reset label.

TCP: check for an active connection before cleaning it up
...
If there is no active connection (e.g. it is waiting in accept), then
the connection object, which doesn't yet exist, should not be cleaned
up when the socket is closed.

TCP: return from write when there is no buffer space
...
During a write, if there is no more buffer space for the user data,
return the amount that was written instead of waiting until there
is free space. If nothing has been written yet, then block as before.
This solves a deadlock that occurs if the user data is too large to
fit in the available buffer: the write thread will block before any
data is added to the write queue, leaving no possibility that more
buffers will free up when they are ACKed (since they have not yet been
sent). The write thread will then block forever and hold all of the
buffers.

TCP: add writable check during poll
...
When a poll requesting POLLOUT happens, the poll should return
immediately if a write will not block. This change adds that, as
opposed to the old behaviour of blocking until a timer from the
Ethernet driver eventually triggers the poll to complete.
This is only implemented for buffered TCP. Unbuffered TCP should
behave as before.

net/tcp: The logic that binds a specific networkd device to a connection was faulty for the case of multiple network devices. On bind(), the local address should be used to associate a device with the connection (if the local address is not INADDR_ANY); On connect(), the remote address should be used (in case the local address is INADDR_ANY). On accept(), it does not matter but the remote address is the one guarenteed to be available.
