+ if (between(tp->snd_up, tcb->seq + 1, tcb->seq + 0xFFFF)) {
+ th->urg_ptr = htons(tp->snd_up - tcb->seq);
+ th->urg = 1;
+ } else if (after(tcb->seq + 0xFFFF, tp->snd_nxt)) {
+ th->urg_ptr = 0xFFFF;
+ th->urg = 1;
+ }What does this make happen for a jumbo frame where the urgent pointer is within this packet, yet is beyond the 0xffff offset limit? I think this can't be used.
