Hi Or, We did not try only NETIF_F_SG for IPoIB CM. We tried it along with NETIF_F_IP_CSUM. We did run into issues with netperf i.e. netperf errors out along with NETIF_F_SG. However, iperf worked fine. Did not investigate that further.On 6/14/2012 7:09 PM, Sridhar Samudrala wrote:Enabling NETIF_F_SG improves the throughput further by avoiding a additional kernel memcpy caused by skb_linearize() in dev_queue_xmit().Hi Sridhar,If you **only** enable NETIF_F_SG for CM, does this yields any gain? did you had to patch the code for that end?
