Public bug reported:
Hi,
I'm running Ubuntu 18.04 kernel 4.15.0-47-generic, openvswitch
2.10.0-0ubuntu2~cloud0 set up by neutron (from openstack rocky) - VXLAN
overlay.
I've found out that as soon as a linuxbrige or bond is involved the
network path of openvswitch, the offloading features of the NIC
(checksumming, segmentation, VXLAN encap) get disabled, which reduces
the throughput a lot.
You can find the flows below. Examples of setup used :
"Normal" setup :
br-bond0 (192.168.11.11)
bond0
enp50s0f0
enp113s0f0 (handling traffic)
Only interface in the bond :
br-bond0 (192.168.11.11)
bond0
enp50s0f0 (handling traffic)
Interface directly in the bridge :
br-bond0 (192.168.11.11)
enp50s0f0
With the setups above, there is NO offloading happening (tcpdump reports
packet sizes of the MTU (~9k)). If the IP address is directly on the
enp50s0f0 interface, then offloading works.
For what it's worth, the NICs are Mellanox MT27800.
Thanks !

Title:
offloading disabled when using linuxbrige or bonding

Hi,
I'm running Ubuntu 18.04 kernel 4.15.0-47-generic, openvswitch
2.10.0-0ubuntu2~cloud0 set up by neutron (from openstack rocky) -
VXLAN overlay.
I've found out that as soon as a linuxbrige or bond is involved the
network path of openvswitch, the offloading features of the NIC
(checksumming, segmentation, VXLAN encap) get disabled, which reduces
the throughput a lot.
You can find the flows below. Examples of setup used :
"Normal" setup :
br-bond0 (192.168.11.11)
bond0
enp50s0f0
enp113s0f0 (handling traffic)

enp50s0f0
With the setups above, there is NO offloading happening (tcpdump
reports packet sizes of the MTU (~9k)). If the IP address is directly
on the enp50s0f0 interface, then offloading works.
For what it's worth, the NICs are Mellanox MT27800.
