In dp_netdev_input() we nevered fully covered the case where handler queues are
not there.

netdev-dpdk: Disable NIC offloading and multiseg mbufs
		
We do not use any offloading (now) or multiple segments per packet, so
we might as well disable those features while configuring the NIC.

This could give performance improvements. For ixgbe, for example, this change
allows the driver to use a simpler tx routine, resulting in throuput
improvements (~7.5%)

netdev-dpdk: Count and delete every dropped packet
		
Commit f4fd623c4c25 introduced a bug in netdev_dpdk_send(): if multiple
consecutive packets exceed MTU, only the first one is deleted and
counted.

This should fix the bug
