[B.A.T.M.A.N.] question about frag_can_reassemble()

Hi Sven,

I had a question about the code in frag_can_reassemble().

net/batman-adv/unicast.h 51 52 merged_size = (skb->len - sizeof(*unicast_packet)) * 2; ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 53 merged_size += sizeof(struct unicast_packet) + uneven_correction; 54 55 return merged_size <= mtu; 56 }

Can the skb->len be less than sizeof(*unicast_packet) (ie 20 bytes)? If "len" is less than 10 then we would return false but if it's over 10 then we would return true. Roughly.
