* Question about IPv6 neighbor discovery and 6lowpan @ 2013-11-21 15:02 Jukka Rissanen 2013-11-21 15:34 ` Alexander Aring 0 siblings, 1 reply; 6+ messages in thread From: Jukka Rissanen @ 2013-11-21 15:02 UTC (permalink / raw) To: David Miller; +Cc: netdev Hi, I am investigating RFC 6775 (Neighbor Discovery Optimization for IPv6 over Low-Power Wireless Personal Area Networks (6LoWPANs)) http://tools.ietf.org/html/rfc6775 The RFC suggests some changes to neighbor discovery procedure for the 6LoWPAN networks. I was looking net/ipv6/ndisc.c and it seems that ARPHRD type (from type field in net_device struct) is the only way to detect and change the discovery procedure in the ndisc.c code. Am I right with this assumption here? Cheers, Jukka ^ permalink raw reply [flat|nested] 6+ messages in thread

But I am investigating for rfc6775, too. :-) At the moment I see too many unsolved issues in the ieee802154/6lowpan implementation which should be fixed at first. :( - Alex ^ permalink raw reply [flat|nested] 6+ messages in thread

The reason I was interested in about this is that I proposed new ARPHRD_RAWIP earlier that I could use in BT LE 6lowpan code. Now I think that type might be too generic and perhaps I should have ARPHRD_6LOWPAN or even ARPHRD_BT_6LOWPAN. > > But I am investigating for rfc6775, too. :-) > > > At the moment I see too many unsolved issues in the ieee802154/6lowpan > implementation which should be fixed at first. :( > > - Alex No worries, the rfc6775 is common for both zigbee and bluetooth so whoever implements the rfc gets support for both of them at the same time.
