Can not use jumbo frames with openvswitch bridge in kernel 4.10. This is fixed in kernel 4.11: Commit 91572088e3fd ("net: use core MTU range checking in core net infra") changed the openvswitch internal device to use the core net infra for controlling the MTU range, but failed to actually set the max_mtu as described in the commit message, which now defaults to ETH_DATA_LEN. This patch fixes this by setting max_mtu to ETH_MAX_MTU after ether_setup() call.
