Missed means the RX buffer is not enough. What's in my mind is that there's= only one buffer shared, so we cannot split it to every VF. So, for VF, we = have to check the PF stats to know there's jam. > Is this the same for dpdk with virtio? Can I know if there where dropps? I think this's another story. Let's wait and see what the virtio experts wi= ll teach us :) >=20 > -----Original Message----- > From: Lu, Wenzhuo [mailto:wenzhuo.lu@intel.com] > Sent: Thursday, March 10, 2016 2:40 PM > To: Yaron Illouz ; dev@dpdk.org > Subject: RE: ixgbevf missed stats >=20 > Hi Yaron, > The stats of PF is done by HW.
