You could have lowpan_fragment_xmit create an entirely new skb, call dev_hard_header, determine how many bytes you can pack into that skb and then do that. If you can transmit that fragment, return the number of bytes transmitted, if you can't, return -ENOBUFS or whatever seems more appropriate. Ideally, also ask mac802154 (somehow, not sure how) about how many bytes you can fit into the fragment instead of using a fixed maximum fragment size. ------------------------------------------------------------------------------ Subversion Kills Productivity.
