Grimes from comment #14) What limits do you suggest? The total number of entries (IP_MAXFRAGS) is limited to nmbclusters / 32, w= hich is 400 in this case, since nmbclusters is 12800. Since we have 1024 queues, only up to 400 could be used. This also means that we can reassemble up to = 400 packets in parallel, as long as the hash value is different. You just can't handle collisions. --=20 You are receiving this mail because: You are on the CC list for the bug.=
