Yes, it is doable. The KNI establishes software based request/response queues
between
vNIC device in kernel and PMD in user space. So all ethtool commands will be
interpreted by
KNI driver and forwarded to PMD which really configure NIC registers.
Basically, it is the only option. Or you have t
15.5 mpps is amazing.
Does the RX core run the distributor or there is another distributor core?

This patch support measure RX burst cycles.
It stops only when all the injected packets are received.
It won't repeat re-send recevied packets.
Now it measures two situations, poll before/after xmit(w or w/o desc. cache

Usage Example:
1. Run unit test app in interactive mode

The unit test to support measure rx or tx only.
Usage Example:
1. Run unit test app in interactive mode
app/test -c f -n 4 -- -i
2. Choose rx or tx standalone, default is both

3. Run and wait for the result

It provides unit test to measure cycles/packet in NIC loopback mode.
It simply gives the average cycles of IO used per packet without test equipment.
When doing the test, make sure the link is UP.
Usage Example:
1. Run unit test app in interactive mode
app/test -c f -n 4 -- -i
2. Run and wait

Hello,
I would like to use KNI interface *only* for the ethtool/ifconfig support,
not for the data packets movement into and from the kernel. For the fast
path, I would like to use PMD. Is this doable? What are the other options
for a PMD driver to support standard linux utilities?
Thanks in adv.,

If you agree, I can fix them before applying the patchset.

Hello All,
When a outgoing packet is sent with data Len more than 1514 which will be a
case in VLAN (Max 1518 ) the packet is getting dropped because of the below
code snippet. This looks incorrect as in case of VLAN .

/* Needs to minus ether header len */
Hi,
I have an application which consists of *.c files and I have been using the
DPDK build system happily so far.
The way I do it is I include the rte.vars.mk and rte.extlib.mk in my
application Makefile.
I set the LIB variable to .a
I set SRCS-y :=
And that's it, it works.

Hi Rashmin,
We found similar issue when we start/stop vmnet dev several time. (> 3 times)
It happens kernel panic, and sometimes kernel will occur core dump.
Let me know if you want to submit patch to fix it.
Thanks

Here is the docker step, it is quite straightforward. Basically they are the
same as LXC.
UIO:
docker run -i -t --device=/dev/uio0:/dev/uio0 --device=/dev/uio1:/dev/uio1 -v
/mnt:/mntfedora20-dpdk-2 /bin/bash
