net: Add GRO support for vxlan traffic

2014-01-22T02:05:04+00:00

Add GRO handlers for vxlann, by using the UDP GRO infrastructure. For single TCP session that goes through vxlan tunneling I got nice improvement from 6.8Gbs to 11.5Gbs --> UDP/VXLAN GRO disabled $ netperf -H 192.168.52.147 -c -C $ netperf -t TCP_STREAM -H 192.168.52.147 -c -C MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.52.147 () port 0 AF_INET Recv Send Send Utilization Service Demand Socket Socket Message Elapsed Send Recv Send Recv Size Size Size Time Throughput local remote local remote bytes bytes bytes secs. 10^6bits/s % S % S us/KB us/KB 87380 65536 65536 10.00 6799.75 12.54 24.79 0.604 1.195 --> UDP/VXLAN GRO enabled $ netperf -t TCP_STREAM -H 192.168.52.147 -c -C MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.52.147 () port 0 AF_INET Recv Send Send Utilization Service Demand Socket Socket Message Elapsed Send Recv Send Recv Size Size Size Time Throughput local remote local remote bytes bytes bytes secs. 10^6bits/s % S % S us/KB us/KB 87380 65536 65536 10.00 11562.72 24.90 20.34 0.706 0.577 Signed-off-by: Shlomo Pongratz Signed-off-by: Or Gerlitz Signed-off-by: David S.

vxlan: Have the NIC drivers do less work for offloads

2013-10-29T09:39:13+00:00

This patch removes the burden from the NIC drivers to check if the vxlan driver is enabled in the kernel and also makes available the vxlan headrooms to them. Signed-off-by: Joseph Gasparakis Tested-by: Kavindya Deegala Signed-off-by: Jeff Kirsher

vxlan: Notify drivers for listening UDP port changes

2013-09-05T16:44:30+00:00

This patch adds two more ndo ops: ndo_add_rx_vxlan_port() and ndo_del_rx_vxlan_port(). Drivers can get notifications through the above functions about changes of the UDP listening port of VXLAN. Also, when physical ports come up, now they can call vxlan_get_rx_port() in order to obtain the port number(s) of the existing VXLAN interface in case they already up before them. This information about the listening UDP port would be used for VXLAN related offloads. A big thank you to John Fastabend (john.r.fastabend@intel.com) for his input and his suggestions on this patch set.
