Here instead of recreating each packet separately, we use clones counter
to resend the same mbuf to the line multiple times.

PMDs handle that transparently due to reference counting inside of mbuf.

Reaching max PPS on small packet sizes helps here:
Some data from our 2 port x 50G device. Using 2*6 tx queues, 64b packets,
PowerEdge R7525, AMD EPYC 7452:

Doing similar measurements per core, I see one core can do

Commit in the fixes line moved the 'DEV_RX_OFFLOAD_JUMBO_FRAME' offload

net/virtio: fix Arm build with old compiler

../drivers/net/virtio/virtio_rxtx_packed_neon.h:
In function ‘virtqueue_enqueue_batch_packed_vec’:

The message shows ‘vreinterpretq_p128_u32’ intrinsic is not supported
