Subject: [dpdk-dev] [PATCH v2 0/3] Use common Linux tools to control DPDK ports
Date: Fri, 12 Feb 2016 13:45:32 +0000	[thread overview]
Message-ID: <1455284735-9606-1-git-send-email-ferruh.yigit@intel.com> (raw)
In-Reply-To: <1453911849-16562-1-git-send-email-ferruh.yigit@intel.com>

This work is to make DPDK ports more visible and to enable using common
Linux tools to configure DPDK ports.

Patch is based on KNI but contains only control functionality of it,
also this patch does not include any Linux kernel network driver as
part of it.

Basically with the help of a kernel module (KCP), virtual Linux network
interfaces named as "dpdk$" are created per DPDK port, control messages
sent to these virtual interfaces are forwarded to DPDK, and response
sent back to Linux application.

Virtual interfaces created when DPDK application started and destroyed
automatically when DPDK application terminated.

Communication between kernel-space and DPDK done using netlink socket.

Currently implementation is not complete, sample support added for the
RFC, more functionality can be added based on community response.

With this RFC Patch, supported: get/set mac address/mtu of DPDK devices,
getting stats from DPDK devices and some set of ethtool commands.

In long term this patch intends to replace the KNI and KNI will be
depreciated.

v2:
* Use rtnetlink to create interfaces
* Add more ethtool support: get/set ringparam, set pauseparam.
* fix ethtool get/set eeprom
* lots of minor updates, enhancements in the code


Samples:

$ ifconfig
dpdk0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        ether 90:e2:ba:0e:49:b8  txqueuelen 1000  (Ethernet)
        RX packets 33  bytes 2058 (2.0 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 33  bytes 2058 (2.0 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

dpdk1: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        ether 00:1b:21:76:fa:21  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

After some traffic on port 0:

$ ifconfig
dpdk0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        ether 90:e2:ba:0e:49:77  txqueuelen 1000  (Ethernet)
        RX packets 962  bytes 57798 (56.4 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 962  bytes 57798 (56.4 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0


$ ethtool -i dpdk0
