Such an argument could certainly be made. Does skb->truesize include the skb header, as well as the buffer space allocated? > (as tho would turn the queue into tail-drop effectively) But fq_codel (and cake) are a little cleverer than that, even when they hit the hard limit. They still drop from the head, and they shoot the longest flow-queue first. - Jonathan Morton _______________________________________________ Codel mailing list [email protected] https://lists.bufferbloat.net/listinfo/codel
