Thanks, Bmac! My Mellanox card isn't IPoIB though. It's an actual 40Gbps Ethernet HCA. I'm sure the silicone is the same as the IB cards but it's hard-wired to function as a pure Ethernet controller...

Hi Yairi, I am not sure I know what you mean... ethtool does not reports counters for packets that have been sent or received via RDMA. thanks,Dan
View ArticleRe: Confusion with Packet and Byte counters for RoCE over ConnectX-3
you are correct. those are not going to know how many RoCE and how many other counters.ethtool -S <ifname> will provide you with bytes, packets for Rx and Tx data. for Infiniband case, things are...
