I also noticed an issue with pktgen sending a limited number (many thousand) of
packets when
using smaller packet sizes (64B, 128B) while using the ixgbe driver with an
X550 (actually,
HPE-branded X550). I had applied the "[dpdk-dev] [PATCH] net/ixgbe: add
support of 2.5G and 5G"
patch from Wei Dai to dpdk-17.08-rc2 before building pktgen-3.3.7 on RHEL 7.3.
I was using pktgen to generate packets on both ports of the X550 at 2.5G and 5G
rates, but
noticed that transmission would stop after a few seconds for smaller packet
sizes.
