Subject: Regarding dev->addr_len
Date: Fri, 08 Aug 2014 14:10:48 +0530	[thread overview]
Message-ID: <53E48D10.3090606@gmail.com> (raw)

Hi Alex,

I need some clarification regarding address length for the netdevice.
We are always setting up that to IEEE802154_ADDR_LEN [1].

If i receive a packet (RS: Router Solicitation) with short addressing mode,
it is discarding at higher layers.

If the linux node receives the RS packet from TinyOS node its discarding
at [2] due to address length field. Here [2] we are getting *lladdr* as NULL.


Actually we have to update the dev->addr_len filed as per the packet info it received ..?

How can we make it work..?
