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.

2eb9abc3d8 net/can: fix can mssage corruption if enable NET_TIMESTAMP 
Timestamp location in can message has changed,
In the original logic timestamp is saved at the end of the data segment:

io_data
   -------------------------------------------------
   |         CAN message            |  Time Stamp  |
   -------------------------------------------------
   |<---------------     io_len   ---------------->|

In the new structure timestamps will reuse NET_LL_GUARDSIZE to isolate CAN messages:
io_data       io_offset
   -------------------------------------------------
   |  Time Stamp  |         CAN message            |
   -------------------------------------------------
                  |<--------    io_len   --------->|

This PR will:
1. Increase NET_LL_GUARDSIZE to 16 (sizeof(struct timeval)) if NET_CAN && NET_TIMESTAMP are enabled
2. Apply timestamp to adapt to the new structure

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)
            |
            |                  io_offset(CONFIG_NET_LL_GUARDSIZE)
            |                                |
            -------------------------------------------------
      iob   |            Reserved            |    io_len    |
            -------------------------------------------------

-------------------------------------------------------------
Layout of different NICs implementation:

        iob_data (aligned by CONFIG_IOB_ALIGNMENT)

            |                                |

 ipforward  |            Reserved            |    io_len    |
            -------------------------------------------------

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

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