Hi, I am using machine with
on board NIC - pci-e connection - Intel Corporation Ethernet Connection I217-LM (rev 04) -e1000e kernel deriver add on card - pci conncetion - Intel Corporation 82540EM Gigabit Ethernet Controller (rev 02) -e1000 kernel driver whenever i bind only I217-LM with igb_uio, testpmd($ sudo ./testpmd -c 0xff -n 4 -- -i) runs well without any error and pmd identify port and everything. but whenever i bind 82540EM with igb_uio, testpmd($ sudo ./testpmd -c 0xff -n 4 -- -i) runs with error "EAL: Error reading from file descriptor 21: Input/output error" though it runs and identify port etc. But continues "EAL: Error reading from file descriptor 21: Input/output error" is printed on screen. So is this error specfic to nic or driver e1000 or pci connection ? I am unable to identify. If i add one more card of Intel Corporation 82540EM Gigabit Ethernet Controller (rev 02) -e1000 kernel driver with pci connection, now it gives two errors "EAL: Error reading from file descriptor 21: Input/output error" and "EAL: Error reading from file descriptor 23: Input/output error" one after another in continues stream I tried for dpdk-2.0.0, dpdk-2.2.0 and dpdk-16.04 What is exact problem behind error and how can we resolve this. -- *Regards,Upendra Sunil PathrikarBharti School of Telecom Technology and Management,Indian Institute of Technology, Delhi.*
