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

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

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

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.

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.

new interface to support iob offload:

025430a964 net/icmpv6: Fix icmpv6_reply function
Fix icmpv6_reply logic broken by commit 48311cc61f and 391b501639.

- 48311cc61f "Fix unaligned memory access when creating ICMP Port Unreachable messages"
  - It removed `htonl` function outside `data`, then the byte order may be wrong, so add `htons` back.
- 391b501639 "net: extract l3 header build code into new functions"
  - It mis-removed the `memmove`, and the icmpv6 has no payload copied after this commit.

23dfdeacab net/nat: Split out ipv4_nat_in/outbound_internal
Split out ipv4_nat_in/outbound_internal which returns entry instead of error code, for later ICMP error types, does not change any current logic.

Reason: Outer packet doesn't have information of port, so we need to find entry by inner packet, and apply the entry to outer packet.

| Outer Packet: SRC = Peer IP<No Port>, DST = External IP<No Port> |
| Inner Packet: SRC = External IP:Port, DST = Peer IP:Port         |

8b211128f1 net/nat: Support param to manipulate src or dest
This commit is for later ICMP error types processing, and does not change any current logic.

Reason for supporting both side of modification is that an inbound ICMP Error MSG may carry original packet like this:

|          IP HDR: SRC = Peer IP,       DST = External IP |
|        ICMP HDR: ERROR MSG                              |
| <Origin> IP HDR: SRC = External IP,   DST = Peer IP     |
| <Origin> L4 HDR: SRC = External Port, DST = Peer Port   |

So we need to support inbound translation (External -> Local) on SRC or DST of each header.

And so do the outbound direction.

a26ea96f3b net/icmpv6: Fix datalen in icmpv6_reply
The `datalen` indicates the whole len of original packet, which will become the payload inside icmpv6 packet.

Using `datalen = (ipv4->len[0] << 8) + ipv4->len[1]` in icmp_reply is correct, because it includes IPv4 header, but when coming to IPv6, the `len` does not include the header, so we need to add it back.

0ec4b0a149 tcp: recv returns 0 without set errno
Issue:
recv return 0  means peer side has already closed the connection according to
man page's description.
0 is returned without set errno when TCP rx timeout happens with current
design.

Solution:
return result instead of ir_result when ir_result is 0, then -1 will be
returned with errno set to EAGAIN for tcp rx buffer empty case.

socket with an invalid port, server cannot find a listener conn
to handle this connet request, then it will response a TCP_RESET

Support ICMP ECHO REQUEST & REPLY. Id of ICMP is processed like port of TCP in NAT. However, our ICMP stack doesn't have a method to manage id allocation like tcp_selectport(), the id is set by apps (like icmp_ping.c) without conflict avoidance, so not adding such conflict avoidance logic to ICMP stack when implementing NAT.
