After chatting with Marcel we need a better UAPI for bringing features into upstream radvd... and maybe RTNL has the feature to get the dev->addr_len. :-) I will try to add the current stuff which we have in debugfs into some netlink UAPI. - Alex -- To unsubscribe from this list: send the line "unsubscribe linux-wpan" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

This patch adds debugfs entry for get the link layer type for userspace. Signed-off-by: Alexander Aring <aar@pengutronix.de> --- Patrik, after changing the dev->addr_len = 6 in btle 6lowpan. I think you should add this patch to the end of your patch series. Then a "recent" radvd will use the correct hardware address length. net/6lowpan/debugfs.c | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+)
