[vpp-dev] Skipping ipv4-input processing in L3Fwd

Hi, In case of L3Fwd, there is a possibility of handing of vlib_buffer from device-input to ipv4-lookup and thereby skipping ipv4-input/ipv4-input-no-chksum completely. All ipv4-input/ipv4-input-nochksum functionalities can be offloaded to hardware and hence the node can be skipped.
