Promicious mode

Hi Think01,

W5500 support MACRAW mode.
Raw packets can be sniff in this mode.

Refer to MACRAW mode in datasheet and reference code as below,

Driver Ethernet (Berkeley Socket type APIs) 1.0.2 :
[url]http://wizwiki.net/wiki/doku.php?id=products:w5500:driver[/url]

In MACRAW mode, socket / sendto / recvfrom / close function are used.

• Socket number ‘0’ can be only open in MACRAW mode.
  socket(0, Sn_MR_MACRAW, dummyport, 0)
  sendto(0, buf, len, dummpyip, dummpyport)
  recvfrom(0, buf, len, dummpyip, dummpyport)
  close(0)

Thanks,
