Can someone please confirm whether this is expected behavior? Why am I not able to see TSO pkts until I re-start iperf session?
Steps to reproduce:- 1. Load if_bnxt (or any other NIC) driver and assign IP 2. start iperf TCP traffic 3. Capture Tx pkts (command: tcpdump -i bnxt0), I can see > 60K length 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. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[email protected]"
