SubjectRe: ipv6 stack seems to forget to send ACKs
From
Date
Hi Wichert,

Looking at your trace it seems that the receiving machine is dropping
all packets that do not have traffic class set. Note that all segments
received with [class 0x2] get properly acked. The others probably don't
get to TCP at all. You might want to check your filters and QoS
policies.

BR,

MikaL
