Wenzhuo,
>From "MAINTAINERS" file in package of dpdk source code, I know that you maintain e1000e driver now, could you help me for an question? I use DPDK-pktgen based on Intel I350-DA2 network adapters, when I loopback two ports on one NIC(I350_eth1 <-> I350_eth2), I got 1Gbps line rate TX throughput. But when I link a Firewall between two ports, just like I350_eth1 -> Firewall_port1 -> Firewall_port2 -> I350_eth2, even I try to burst tx throughput as line rate by power CPU cores, it only get 600Mbps tx throughput which is firewall's rx speed, seem the tx speed from I350 just depend on peer firewall rx capability. I try this on others network adapters like X520-DA2 and X710DA2, both of them got different results, tx speed only depend on CPU power, but no related with rx capability of network devices. Could you know why of this? Is there any configuration/interface/register update this feature? Let us send packet with line rate, but not care rx speed. / # lspci | grep I350 0e:00.0 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01) 0e:00.1 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01) / # Thanks and Regards, Haifeng
