6lowpan netlink

6lowpan netlink

[Alexander Aring]

Hi all,

I want to spread around that I started to work on some overdue
implementation, a netlink 6lowpan configuration interface, because
rtnetlink is not enough... it's for configuring very specific 6lowpan
device settings.

Thanks.

I would like to trigger a discussion about rtnetlink or generic. I can
put a nested rtnetlink for some device specific settings but then the
whole iproute2 (as it's currently is) would maintain a specific
6lowpan setting which maybe the user never wants...
I think we should follow this way when there is a strict ipv6 device
specific setting e.g. l2 neighbor information in ipv6 ndisc.

Unless you'll have to repeat attributes which are already present 
in rtnetlink in an obvious way genetlink > rtnetlink.

I think this is not the case, I do not implement a new protocol
family... I just need to manipulate some 6lowpan stack settings that
aren't part of the current ipv6 protocol familty rtnetlink operations.

Thanks.
