Low Cost 10G Router

Somebody definitely should build full feature router with DPDK/netmap/pf_ring :)
I have finished detailed performance tests for all of them and could
achieve wire speed forwarding (with simple packet rewrite and checksum
calculation) with all of they.
I.e. I could process 10GE and 14.6 mpps (64byte packets) on very cheap
i7 3820 with single intel X540 NIC (total cost about $ 800) with CPU
But full BGP routing is a challenge but could be implemented with
existing approaches like DXR:
