Subject: What does this code do

While browsing the Linux networking code I came across these two lines
in __ip_append_data() which I do not understand.

                /* Check if the remaining data fits into current packet. */
                copy = mtu - skb->len;
                if (copy < length)
                        copy = maxfraglen - skb->len;
                if (copy <= 0) {

Why not just use maxfraglen.

Perhaps someone can explain why this is needed.

Regards
