Why did you submit this _4_ times? I'm deleteing everything, I'm not even going to try and guess why you submitted this so many times and what might be different between each copy. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
sorry for wrongly use git, I cannot recall them back. There is no different between them. Anything else I can fix this?

we do have some USB net devices, which cannot do ARP. so we can introduce a new flag FLAG_NOARP, then client drivers can easily handle these kind of devices Signed-off-by: Wei Shuai <cpuwolf@gmail.com> --- drivers/net/usb/usbnet.c | 4 ++++ include/linux/usb/usbnet.h | 1 + 2 files changed, 5 insertions(+), 0 deletions(-)
