Subject: sch_netem: more precise length of packets
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8cfd88d6d70735c47b17aef855b4c81dde83c85c;p=linux-beck.git

sch_netem: more precise length of packets

With TSO/GSO/GRO packets, skb->len doesn't represent
a precise amount of bytes on wire.
This patch replace skb->len with qdisc_pkt_len(skb)
which is more precise.
