Hello

I'm trying to install DPDK on my laptop.

I have 82579LM NIC which i'm trying to bind to the igb_uio driver. I get
the following error

# ./tools/pci_unbind.py --status

Network devices using IGB_UIO driver
====================================
<none>

Network devices using kernel driver
===================================
0000:00:19.0 '82579LM Gigabit Network Connection' if=eth0 drv=e1000e
unused=

Other network devices
=====================
<none>


# ./tools/pci_unbind.py --force --bind=igb_uio 00:19.0
Error: bind failed for 0000:00:19.0 - Cannot bind to driver igb_uio
Error: unbind failed for 0000:00:19.0 - Cannot open
/sys/bus/pci/drivers//unbind

After this, the --status shows this :

# ./tools/pci_unbind.py --status

Network devices using IGB_UIO driver
====================================
<none>

Network devices using kernel driver
===================================
<none>

Other network devices
=====================
0000:00:19.0 '82579LM Gigabit Network Connection' unused=e1000e


My kernel version is 3.5.0-23-generic ( Ubuntu 12.04.2 LTS). I heard about
an UIO bug in 3.10; is this the same bug i;m hitting?

Thanks
Jyoti
