I see some differences in received bw for=20 offload=3D1 and 0 though Just using tsn_talker and tsn_listener: tc qdisc add dev eth2 parent 8001:1 cbs idleslope 20000 sendslope -980000 \ hicredit 30 locredit -1470 offload 1 with offload=3D1 (20Mbps BW) Receiving data rate: 19420 kbps Receiving data rate: 19410 kbps Similarly, but with offload=3D0 (SW, 20Mbps BW) Receiving data rate: 19980 kbps Receiving data rate: 20170 kbps So slightly higer variance in rate when doing SW, which is as expected. I plan to run this through some more tests tomorrow and measure variance on= the=20 receiver etc, I'll keep you posted on my findings.
