e10fda570b udp: change PKTINFO flag to socket_conn_s struct 
move the IPPROTO_IP/IPPROTO_IPV6 flag into the socket_conn_s structure to
make it more than just control udp.

26e2e1e32f net/udp: Remove wrong check in udp_readahead 
- Before IOB offload, srcaddr / src_addr_size / ifindex are written into
  IOB by iob_trycopyin, so io_pktlen > 0 is always true, this check is
  correct at that time. (It won't fail with zero-length UDP datagram.)
- After IOB offload, srcaddr / src_addr_size / ifindex are written into
  offset 0, without increasing io_pktlen. So this check will fail with
  zero-length UDP datagram now.
- We need to support zero-length UDP datagram and this check is
  unnecessary at this point.

c288752bef recvmsg: control msg support multi-attribute return 
adapts to third-party code compilation. in the process of porting ConnMan,
multiple control message options are enabled, such as IPV6_RECVPKTINFO and
IPV6_RECVHOPLIMIT, so I changed the Filling implementation of the control
message.

a2097cfb71 net: modify find device logic 
The priorities for finding a network adapter are as follows:
1. if laddr is not ANY, use laddr to find device;
2. if laddr is ANY, and bound index is not 0, use bound index
   to find device;
3. if laddr is ANY and no device is bound, use raddr to find
   device.

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

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.

34d2cde8a8 net/l2/l3/l4: add support of iob offload 
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

------------------------------------------------------------

        iob_data (aligned by CONFIG_IOB_ALIGNMENT)

            -------------------------------------------------

--------------------------------------------------------------------

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:

  ------------------------------------------
  |    IOB version     |     original      |
  |----------------------------------------|
  |  devif_iob_poll()  |   devif_poll()    |
  |       ...          |       ...         |
