I've just started working with DPDK recently, and I'm a little confused by the intended behavior when transmitting and receiving on the same port.
Currently, I haven't been able to receive the same packet that I transmitted, regardless of the source/destination MACs on the Ethernet packet (broadcast, self, etc), or whether the port is in promiscuous mode. I've verified from other hosts on the network that my packets are being sent, that I am able to receive packets (as long as I didn't send them), and that I get the same behavior when using vfio-pci with both e1000 and vmxnet3 (emulated in VMware). Is there some built-in source MAC filtering that I'm missing? Or do I have to enable loopback mode? Thanks, Dominic
