module loading, please include the output from the "dmesg" and
"modinfo" commands mentioned above.
+ There is an optional module parameter to openvswitch_mod.ko called
+ vlan_tso that enables TCP segmentation offload over VLANs on NICs
+ that support it. Many drivers do not expose support for TSO on VLANs
+ in a way that Open vSwitch can use but there is no way to detect
+ whether this is the case. If you know that your particular driver can
+ handle it (for example by testing sending large TCP packets over VLANs)
+ then passing in a value of 1 may improve performance. Modules built for
+ Linux kernels 2.6.37 and later do not need this and do not have this
+ parameter. If you do not understand what this means or do not know if
+ your driver will work, do not set this.

% ovsdb-tool create /usr/local/etc/ovs-vswitchd.conf.db vswitchd/vswitch.ovsschema
