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.*
