b33474cb11 free TCP rx buffer immediately in tcp_close 
Issue:
TCP rx buffer is freed after 4-way handshake with current design.
3 socket's rx buffer might be consumed during ffmpeg switch music procedure,
and this might cause IOB exhausted.

Solution:
free TCP rx buffer immediately in tcp_close to make sure IOB won't be
exhausted.

cc940e8f69 net_lock:fix deadlock issue when running iperf tx test on usrsock 
Issue Description:
deadlock happens when runnging iperf TCP tx on usrsock with the
following commands：
device command: iperf2 -c <PC IP address> -u -i 1 -p 1122  -t 10
PC command: iperf -s -u -i 1 -p 1122

iperf's thread holds net_lock before call usrsock_setup_request_callback
and waits for conn->resp.sem by calling
nxsem_wait_uninterruptible(&conn->resp.sem), while conn->resp.sem
can only be signaled in usrsock_response, who is waiting for net_lock in
tptun's thread.

Solution:
call net_lockedwait_uninterruptible to make sure net_lock can be
released when conn->resp.sem is not available.

fbe641a916 socket:return -EAGAIN if timeout happends in psock_tcp_send 
psock_tcp_send will enter busyloop state when no IOB keeps at unavailable state
when the socket is blocking socket and this will cause WDT.
According to socket's manpage, -1 should be returned while errno set to EAGAIN
if send/recv timeout was set.

Here's the description:
SO_RCVTIMEO and SO_SNDTIMEO
Specify the receiving or sending timeouts until reporting an error. The argument is a struct timeval. If an input or output function blocks for this period of time, and data has been sent or received, the return value of that function will be the amount of data transferred; if no data has been transferred and the timeout has been reached then -1 is returned with errno set to EAGAIN or EWOULDBLOCK, or EINPROGRESS (for connect(2)) just as if the socket was specified to be nonblocking. If the timeout is set to zero (the default) then the operation will never timeout. Timeouts only have effect for system calls that perform socket I/O (e.g., read(2), recvmsg(2), send(2), sendmsg(2)); timeouts have no effect for select(2), poll(2), epoll_wait(2), and so on.

2afa1b3b64 net/udp: correct linger timeout 
UDP linger timeout will be wrongly converted to UINT_MAX by _SO_TIMEOUT() when it is set to 0,

net/socket/socket.h:
|
| #  define _SO_TIMEOUT(t) ((t) ? (t) * MSEC_PER_DSEC : UINT_MAX)

net/udp/udp_close.c:
|
| if (_SO_GETOPT(conn->sconn.s_options, SO_LINGER))
|   {
|     timeout = _SO_TIMEOUT(conn->sconn.s_linger);
|   }

this change will correct this behavior, if the linger is set to 0, the timeout value should be 0

43cc4bd7bf net_local: fix error when work with epoll 
epoll_wait collects revent by checking fds->revent,
but local_socket will copy fds to the other two private pollfd shandow struct,
then the pipe_poll will not be able to update fds->revent directly,
so need local_socket save fds and implement a private poll_notify function
to passing revent to original fds->revent.

34ade7a0b6 net/devif: fix devif_poll loop logic 
Previously, the devif_poll works in this flow:
devif_poll_xx -> bstop = callback -> continue if !bstop -> poll another

Now we split the polling and callback, so it should work like:
devif_poll_connections -> return true if callback need to be called
   -> bstop = callback -> loop if !bstop -> poll again

Conditions:
poll_connections == 0, d_len == 0, break, return 0
poll_connections == 1, d_len == 0, break, return 1 (other stop case,
                                                    don't callback)
poll_connections == 1, d_len > 0, callback == 1, break, return 1
poll_connections == 1, d_len > 0, callback == 0, loop

7f9cf184e5 net/devif_loopback: Add robustness to avoid infinite loop 
When ipv4_input/ipv6_input called by devif_loopback writes wrong data into buffer (another bug we're fixing), the else block does nothing but only record the 'dropped' statistic, then infinite loop happens.

Refers to previous lo device with dropping logic:

Fragmentation of network data will intensify iob consumption, if
the device receives a message storm of fragmented packets, the iob
cache will not be effectively used, this is not allowed on iot devices
since the resources of such devices are limited. Of course, this
also takes some disadvantages: data needs to be copied.
This option will brings some balance on resource-constrained devices,
enable this config to reduce the consumption of iob, the received iob
buffers will be merged into the contiguous iob chain.

1. Add new config CONFIG_NET_LL_GUARDSIZE to isolation of l2 stack,
   which will benefit l3(IP) layer for multi-MAC(l2) implementation,
   especially in some NICs such as celluler net driver.

new configuration options: CONFIG_NET_LL_GUARDSIZE

CONFIG_NET_LL_GUARDSIZE will reserved l2 buffer header size of
network buffer to isolate the L2/L3 (MAC/IP) data on network layer,
which will be beneficial to L3 network layer protocol transparent
transmission and forwarding

2. Support iob offload to l2 driver to avoid unnecessary memory copy

Support send/receive iob vectors directly between the NICs and l3/l4
stack to avoid unnecessary memory copies, especially on hardware that
supports Scatter/gather, which can greatly improve performance.
