ifconfig eth0
eth0	Link encap:Ethernet HWaddr 42:d3:59:ad:5a:2f at RUNNING mtu 1500

fdc6dbf176 netlink: add RTM_NEWADDR, RTM_DELADDR and RTM_GETADDR 
We have projects that need to sense ip address changes in time,
and set ip address or clear ip address through netlink
so the relevant implementation is added.
The usage and command structure are consistent with linux

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.

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

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

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

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:

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

  |----------------------------------------|
  |  devif_iob_poll()  |   devif_poll()    |

d09304008e net: Fix sa_family returned by SIOCGIFHWADDR 
* net/netdev/netdev_ioctl.c:
  (netdev_ifr_ioctl): The ioctl SIOCGIFHWADDR provides the hardware
   address (e.g., Ethernet MAC, etc.) of a network interface. It is
   based on Linux. (BSD-based systems don't have this ioctl.) The Linux
   implementation sets sa_family to ARPHRD_ETHER for Ethernet and IEEE
   802.11 interfaces [1]. NuttX was setting it to NET_SOCK_FAMILY for
   these interface types as well as 6LoWPAN and PKTRADIO; this was
   incorrect and also the value of NET_SOCK_FAMILY varies based on
   Kconfig settings. Correcting this to ARPHRD_ETHER for Ethernet and
   IEEE 802.11 and ARPHRD_IEEE802154 for 6LoWPAN and PKTRADIO.

6c4bd5c5ef net: Fix memcpy() size used by SIOCSIFHWADDR for radios 
* net/netdev/netdev_ioctl.c:
  (netdev_ifr_ioctl): The ioctl SIOCSIFHWADDR sets the hardware address
   (e.g., Ethernet MAC, etc.) of a network interface. Radio devices may
   have different lengths of hardware addresses, such as
   NET_6LOWPAN_EADDRSIZE (8), NET_6LOWPAN_SADDRSIZE (2), or
   RADIO_MAX_ADDRLEN (8). Also, Kconfig CONFIG_PKTRADIO_ADDRLEN allows
   the user to set any arbitrary size. Note that while the sister ioctl
   SIOCGIFHWADDR "get hardware address" copies
   `dev->d_mac.radio.nv_addrlen` bytes, SIOCSIFHWADDR was copying
   NET_6LOWPAN_ADDRSIZE bytes unconditionally. Depending on which radio
   is used, this could be incorrect. Fixing it to use
   `dev->d_mac.radio.nv_addrlen` for SIOCSIFHWADDR as well. Also adding
   DEBUGASSERT to ensure this is within bounds of source and
   destination of the copy.
