Hello,
We are using Intel 82540EM Gigabit Ethernet Controller NIC card to
capture packets from multicaste ip address. As given in dpdk tutorial,
we need to bind an NIC before using it with dpdk application. The script
'dpdk_nic_bind.py' helps in binding the NIC to dpdk driver, but we are
unable to bind the given NIC. The error shown is as follows:
Error: bind failed for 0000:01:02.0 - Cannot bind to driver igb_uio
Error: unbind failed for 0000:01:02.0 - Cannot open
/sys/bus/pci/drivers//unbind
However, I have Intel 82579LM Gigabit Network Connection as my secondary
NIC, which is able to bind with the dpdk driver using the same script.
Can you please help in debugging this issue? The system used has Centos
6.7 OS and 2.6.32 kernel version.
Thank you,
K Rahul
