https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D222775 Bug ID: 222775 Summary: After re-enabling TSO, not seeing TSO pkts until restart iperf command Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: bhargava.marreddy@broadcom.com Staps to reproduce:- 1. Load if_bnxt driver 2. start iperf TCP traffic 3. Capture Tx pkts (command: tcpdump -i bnxt0), I can see > 60K lengh pkts. 4. Disable tso (command: ifconfig bnxt0 -tso) 5. Capture Tx pkts (command: tcpdump -i bnxt0). Max pkt length seen is 1440 (non-tso pkts) 6. Enable TSO (command: ifconfig bnxt0 -tso) 7. Capture Tx pkts (command: tcpdump -i bnxt0). Max pkt length seen is still 1440 (I was expecting TSO pkts here). 8. Terminate iperf sessions and start again. Now, I can see TSO pkts. Can someone please confirm whether this is expected behavior?=20 Why am I not able to see TSO pkts untill I re-start iperf session? --=20 You are receiving this mail because: You are the assignee for the bug.=
