I'm not totally sure about the capabilities of the e1000 NIC but based on the error you've mentioned, it seems that it can only support 1 TX queue. "Now, I can use only one logic core to run the app and the performance of l3fwd is undesirable." This shows that dpdk can run successfully with 1 TX queue only because probably your e1000 NIC only supports 1 queue.
