[dpdk-users] Setting real MAC address in KNI application

[dpdk-users] Setting real MAC address in KNI application

[Sushil Adhikari]

When I run the DPDK KNI application it gives random mac address to the
ethernet ports. How can I configure it to set up the real MAC address of
the hardware(ethernet ports)? It seems like I can get mac address by
calling rte_eth_macaddr_get but to set up I need to call kni_net_set_mac
which takes in net_device structure which again I don't have access to from
my application. Is there a way to set up the mac address of dpdk ports to
its original mac address in kni application.

Hey Suchil,
Just add a MAC to your /etc/network/interfaces:

iface kni0 inet static
hwaddress 10:20:30:40:50:60

Regards,
Andriy

Thank you for the replay but I am trying to do it in the KNI application
which runs before bringing the network up. I found one recent patch which
seem to work
http://dpdk.org/dev/patchwork/patch/24067/

I applied the patch and added mac address in configuration parameter of
struct rte_kni_conf.
