I am sure, "[eth_drv_ioctl] Warning: Driver can't set multi-cast mode"
doesn't interfere normal IPv4 opreations. Maybe there are some hardware

I got this waring on my target using dp83902a driver, and it doesn't
matter.
However I have added the multicast support, and will contribute it after
full test.
