Add 2 configurations
1. Config to drop recived packet
CONFIG_NET_TCP_DEBUG_DROP_RECV=y
CONFIG_NET_TCP_DEBUG_DROP_RECV_PROBABILITY=50 /* Default drop probability is 1/50 */

2. Config to drop sent packet
CONFIG_NET_TCP_DEBUG_DROP_SEND=y
CONFIG_NET_TCP_DEBUG_DROP_SEND_PROBABILITY=50 /* Default drop probability is 1/50 */

8a63d29c6e net/devif_poll: optimize device buffer alloc in txpoll 
Allocate the device buffer only if the protocol really need to send data.
not all protocols require the driver to prepare additional iob before
sending, especially UDP, each iob reserves l2/l3 header in advance
after prepare write buffer, net device could reuse this entry to send directly

d87620abc9 net: downgrade iob priority of input/udp/icmp to avoid blocking devif 
When trying to use iperf2, we found it comsumes all the IOB when sending UDP packets, then devif_poll has no IOB to send the packet out, so speed drops to 0 and never recovers.

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

879c337e30 net/nat: Use hashtable to optimize performance 
Performance tested on simulator:

Before optimization:      -25% bandwidth @2k entries, -64% @10k entries
hashtable size=  2(1bit): -24% bandwidth @2k entries, -65% @10k entries
hashtable size=  4(2bits):-15% bandwidth @2k entries, -51% @10k entries
hashtable size= 32(5bits): -3% bandwidth @2k entries, -14% @10k entries
hashtable size=256(8bits): -1% bandwidth @2k entries,  -3% @10k entries

Note: Tested on worst performance, the earliest entry will be the worst.

794adc5814 net/tcp: contig received data to reducing iob consumption 
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.
