Re: [PATCH 1/9] batman-adv: add UNICAST_4ADDR packet type

To push this question in a direction: May I assume that the driver always 
ensures that the ethernet header is 4 byte boundary - NET_IP_ALIGN (2) 
aligned?

Yes.

When yes, this would result in a slight variations of your suggestion: 
unicast/bcast headers have to end at 4 bytes boundary + 2 bytes. The reason is 
easy to explain. batman-adv unicast/bcast headers are used to encapsulate the 
important parts of an ethernet frame:

Ethernet Header for P2P | batman-adv header stuff | ethernet header | payload.

Would you aggree?

Then you can get rid of the packed crap.
