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.

6e36a6f14c ethernet: add ETHERTYPE define 
adapts to third-party code compilation. in the process of porting ConnMan,
we encounter some situations where the structure is not defined, or the
returned data types do not match the expectations. Refer to the common
implementation of other systems and add relevant definitions.

277e0b941a include/sys/socket.h: Add SOCK_CTRL to socket type 
SOCK_CTRL is added to provide special control over network drivers
and daemons. Currently, SOCK_DGRAM and SOCK_STREAM perform this control,
but these use socket resources. In the case of usersocket in particular,
this is a waste of the device's limited socket resources.

2a780e0467 net/ipfwd: fix devif_forward after IOB offload. 
Problem:
- `iob_copyout` to `d_buf` doesn't set `io_len` of the IOB, so `devif_poll` failed to copy the data into `buf` by `iob_copyout`

Modification:
- Just Move the IOB in `devif_forward`.

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

------------------------------------------------------------
Layout of frist iob entry:

        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()    |
  |       ...          |       ...         |

4281acdb83 net/chksum: move all chksum api declarations to common header 
The following APIs need to be overriden by the arch after enabling
CONFIG_NET_ARCH_CHKSUM, move these functions to the common header
file to avoid prototype conflicts

uint16_t chksum(uint16_t sum, FAR const uint8_t *data, uint16_t len);
uint16_t net_chksum(FAR uint16_t *data, uint16_t len);
uint16_t ipv4_upperlayer_chksum(FAR struct net_driver_s *dev, uint8_t proto);
uint16_t ipv6_upperlayer_chksum(FAR struct net_driver_s *dev,
                                uint8_t proto, unsigned int iplen);
