command "ip" is not fully supported in busybox?

Question

everybody, I using busybox 1.2.1 as my shell in embedded linux runing on Xilinx Zynq ARM Cortex x2.Any command that busybox support is ok but "ip".In busybox, I tried "ip",it shows that:

BusyBox v1.21.1 (2013-08-15 15:21:48 CST) multi-call binary.

Usage: ip [OPTIONS] {address | route | link | tunnel | rule} {COMMAND}

ip [OPTIONS] OBJECT {COMMAND}
where OBJECT := {address | route | link | tunnel | rule}
OPTIONS := { -f[amily] { inet | inet6 | link } | -o[neline] }

Then I try to use "ip" to configure "can0"(Controller Area Network device),the fully command shows below:

ip link set can0 type can bitrate 125000

This command is ok in my desktop Linux,but busybox says that:

ip: either "dev" is duplicate, or "type" is garbage

So I'm confused.I need this command to configure my "can0",could anybody help me solve this promblem? Thanks very much!

http://www.armadeus.com/wiki/index.php?title=CAN_bus_Linux_driver In this site they have mentioned to rebuild busybox for the ip command for the error you are receiving.

Alternatively you can control can interface via netlink protocol. See http://www.pengutronix.de/software/libsocketcan/download/ or libnl (http://lists.infradead.org/pipermail/libnl/2012-November/000817.html)
