Subject: KNI interface operational state UP issue
Date: Fri, 9 Jan 2015 17:20:26 -0800	[thread overview]
Message-ID: <CAFGSfknTNGabm_+2o7TTQE-HN-exXkGFzuNj83hDTDvwUSRwZw@mail.gmail.com> (raw)

I am using the dpdk1.6.0r1
The rte_kni.lo is loaded:
lsmod | grep kni
rte_kni               279134  1

however, the ifconfig vEth0, and vEth1 does not show link up ?
How do i get the operational state up for these interfaces.
$ sudo tcpdump -i vEth0
tcpdump: vEth0: That device is not up

ifconfig vEth0
vEth0     Link encap:Ethernet  HWaddr 00:00:00:00:00:00
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:12 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:3388 (3.3 KB)  TX bytes:0 (0.0 B)

 ifconfig vEth1
vEth1     Link encap:Ethernet  HWaddr 00:00:00:00:00:00
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:60 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:10252 (10.2 KB)  TX bytes:0 (0.0 B)

These KNI interfaces are created as per dmeg below from the CREATE IOCTL.
sudo ifconfig vEth0 192.168.0.11 netmask 255.255.0.0
SIOCSIFFLAGS: Timer expired
aziz@fast-1:~/stm15-0108/stm/dpdk/dpdk-1.6.0r1_ss/lib/librte_eal/linuxapp/kni$
ifconfig vEth0
vEth0     Link encap:Ethernet  HWaddr 90:e2:ba:5f:1a:64
          inet addr:192.168.0.11  Bcast:192.168.255.255  Mask:255.255.0.0
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:50 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:14488 (14.4 KB)  TX bytes:0 (0.0 B)

Trying to set the vEth0 up, looks like it is doing the callback in the dpdk
to the corresponding PMD NIC interface, and not the vEth0 kernel interface.


Thanks,
