Bhasker Hariharan	e0b3d3323f	Add support for using PACKET_RX_RING to receive packets. PACKET_RX_RING allows the use of an mmapped buffer to receive packets from the kernel. This should cut down the number of host syscalls that need to be made to receive packets when the underlying fd is a socket of the AF_PACKET type.

Reduce PACKET_RX_RING memory usage

Previous memory allocation was excessive (80 MB). Changed
it to use 2 MB instead. There is no drop in perfomance due
to this change:

ab -n 100 -c 10 http://server/latin10m.txt  ==> 10 MB file
80 MB: 178 MB/s
 2 MB: 181 MB/s

Add support for using PACKET_RX_RING to receive packets.

PACKET_RX_RING allows the use of an mmapped buffer to receive packets from the
kernel. This should cut down the number of host syscalls that need to be made
to receive packets when the underlying fd is a socket of the AF_PACKET type.
