dpdk: dpdk-input optimizations and fixes
- fix issue caused by assumption that ethertype starts at 0 - intoduce buffer templates to speed-up vlib_buffer_t metadata initialization - avoid check for multiseg buffers inside loop if multiseg is disabled - interleave prefetches to reduce load on L1 cache Change-Id: I3b76e6d3e1e15ed28f01625edb7fbe9f38112e03 Signed-off-by: Damjan Marion <damarion@cisco.com>
