After compiling DPDK, load module and start our process. A common problem is we have no idea where is the NIC going :).
And DPDK actually provides some tools for these operations, one of them is
dpdk-devbind.py. It located at
We can use it to get current status:
$ dpdk-devbind.py --status # shorthand $ dpdk-devbind.py -s
$ dpdk-devbind.py --bind e1000e 00:06.0 # shorthand $ dpdk-devbind.py -b e1000e 00:06.0 # we also can use NIC name, but remember that a NIC could have no name # only PCI would always existed. $ dpdk-devbind.py -b igb_uio eth1
$ dpdk-devbind.py --unbind 00:06.0 # shorthand $ dpdk-devbind.py -u 00:06.0 # equal to $ dpdk-devbind.py --bind none 00:06.0
p.s. Remember that these operations requiring permission(
sudo or what).
Just that, have fun!
