Hello,
since the invocation of ipv6_add_dev() at NETDEV_REGISTER time in
addrconf_notify() i get an 'add_dev failed' when registering a netdevice
with a MTU of 16.
As the code doesn't check for ipv6 capable hardware types it simply runs
into an error for some non-ipv6 capable networking hw ...
This patch below may just be a hint - maybe you find any 'nicer'
implementation for this.
Best regards,
Oliver
