Why? skb->len is not limited to a u16. The only affect is when skb->len is used to fill in the ipv4/ipv6 header.Seriously ? Have you looked recently at core networking stack, and have you read my netdev presentation ?

Core networking stack will trim your packets skb->len based on what is found in the network header,
Core networking stack is s/w under our control; much more complicated and intricate changes have been made.
