Greetings
I am working on testing a DPDK based VM and need to see if packets are really leaving the host interface. I am using an HP DL-380 server with Intel based 10G nics. I have enabled SR-IOV and am using 1 VF on each of 2 PFs. I want to sniff packets on the host but when I start tshark on the PF device I do not see any packets. but I know they are are passing to the VM (some of them anyway). How can you setup the PF to be able to see
traffic to the VF or when the VF is enabled it completely bi-passes this capability?
