Hi, The ‘mtu’ field of the Interface table is a read-only field in OVSDB, hence it can’t be set via a call to ovs-vsctl.
Work is currently underway to provide a mechanism to modify netdev parameters dynamically at runtime; such parameters could include # RX queues, MTU, etc. See here: http://openvswitch.org/pipermail/dev/2016-April/069835.html In the meantime, if you’d like to play around with Jumbo frames and OVS-DPDK, you can use this patchset: http://openvswitch.org/pipermail/dev/2016-February/066405.html. Note, however, that this patchset is superseded by the aforementioned ‘dynamic netdev reconfigure’ series, and will not form part of the OVS codebase.
