ringmap. #6, #7

[Alexander Fiveg]

In the #6 week, I was at home and I could not manage my work on project. Last 
days of #6-week I improved ringmap according to John Baldwins suggestions: 

+ now ringmap does not try do determine the type of adapter in order to set 
hardware dependent functions. This work does the native driver (em) and the 
native driver passes the pointer to the  hardware-dependent functions as 
parameter by calling ringmap_attach()

Week #7
+ ringmap partly integrated with ixgbe. Multiple queues support  is not made 
yet.
