Hi Stephen, Ferruh,
As an end-user take on this (hence community comment) :), this ties into
the rte_eth_tap that Keith sent out and it has been acked and reviewed, So
I am trying to see the pros/cons of using this (kni pmd) vs. the tun/tap
PMD [1].
Previously, we were using Ferruh's KDP/KCP patc

Thank you, Ferruh.
As we are staying on the existing implementation, I think we can do some
improvements:
1. Implement more commands for net_device_ops.
2. Implement ethtool support the same way as net_device_ops are implemented
? send commands to application.
3. Add ability to set default MAC add

That's probably a smart alternative for packet injection.

Hi,
There was an "Interworking with the Linux Kernel" discussion in the DPDK
userspace event, this mail is to summarize the output and to get more
comments from community.
Briefly, KNI mostly will stay as it is as an interworking with the Linux
kernel solution.
Out of tree kernel module concern

That is a myth. Both require the some number of copies.
TUN/TAP copies is a syscall and KNI copies is a kthread.
Actually, the KNI method
