[lwip-devel] IPv6 Neighbour Advertisement without link-layer address option

[Philipp Tölke]

Hi everyone,

I noticed that lwip does not accept IPv6 Neighbour Advertisement 
messages without the link-layer address option.

By default the linux-kernel sends solicited NA messages without this 
option (you can switch it on with "sysctl -w 
net.ipv6.eth0.conf.force_tllao=1").

Is there a reason for not acception NA messages without the link-layer 
address option? If not, I would like to implement and submit a patch.

Regards,
Philipp
