Hello,
We did pktgen over LAN testing for several hours:
iftop

<= 92.7Mb 92.7Mb 92.5Mb
─────────────────────────────────────────────────────────────────────────────────────────────────────────────────────
TX: cumm: 2.50MB peak: 57.7Kb rates: 7.71Kb 5.97Kb 10.7Kb

TOTAL: 28.0GB 92.9Mb 92.7Mb 92.8Mb 92.6M
Without any problems.
