5 #  - If correctly tuned[1], single CPU 10G wirespeed small pkts is possible[2]
7 # Using pktgen "burst" option (use -b $N)
8 #  - To boost max performance
9 #  - Avail since: kernel v3.18
10 #   * commit 38b2cf2982dc73 ("net: pktgen: packet bursting via skb->xmit_more")
11 #  - This avoids writing the HW tailptr on every driver xmit
12 #  - The performance boost is impressive, see commit and blog [2]
