Since this would be on the order of a second after submission, this seems unlikely then. The even better solution would be if the hardware timed-out an old packet by itself after about 1 second. Does this happen already? If not, can it? - Jonathan _______________________________________________ Bloat mailing list [email protected] https://lists.bufferbloat.net/listinfo/bloat
