So: 1. copy the whole jumbo skb into fragmented one 2. reduce the MTUyou'll not reduce MTU of established connections though. And trying to advertise MSS changes in the middle of a TCP connection is an awful hack which I think will not work everywhere.
Not to mention that Ethernet isn't just IP, so the protocol that is being used might not have a concept of path MTU discovery at all.
