Hi, there is a problem with the software implementation of TAPRIO and TCP communication. When using short intervals e.g. below one millisecond, large packets won't be transmitted. That's because the software implementation takes the packet length and calculates the transmission time. If the transmission time is larger than the configured interval, no packet will be transmitted. Fix that by segmenting the skb for the software implementation.
Tested with software only and full hardware offloading applied using iperf3. Vinicius, do you mind testing as well? Changes since RFC: * Move segmentation, so that timestamps for tx assisted mode are calculated for the segments * Skip it for the full hardware offloading case Previous versions: * https://lkml.kernel.org/netdev/20210312092823.1429-1-k...@linutronix.de/ Kurt Kanzenbach (1): taprio: Handle short intervals and large packets net/sched/sch_taprio.c | 64 +++++++++++++++++++++++++++++++++++------- 1 file changed, 54 insertions(+), 10 deletions(-) -- 2.20.1
