Thanks for your reply. Your guess is right. I run the openvswitch+dpdk with vmxnet3. 
First,I set the nb_desc of rx queue to 2048, and then stop the device, change nb_desc to 4096.
When I start the device again, I get the openvswitch crash caused by dpdk. Writing a sample program based on dpdk, I also get a crash.
The e1000 dpdk driver allocates RX ring for max possible mumber of hardware descriptors. I guess vmxnet3 should be in the same case.
I will submit v3.
