https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=268490 --- Comment #49 from Santiago Martinez <sm@codenetworks.net> --- Hi Daniel, from the config posted seems to be diff,but maybe i miss understood the first msg.Anyhow the behavior that Marek is describing is not limited only to those cards. You can increase the MTU on the phy or reduce the mtu on the logical. I can see the same issue with IXL, BNXT and so on. This is an output from my lab machines. ixl2: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 9000 ixl2.1011: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 9000 BR_DCN_PF: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9000 Connecting to host 192.168.11.42, port 5201 [ 5] local 192.168.11.41 port 42631 connected to 192.168.11.42 port 5201 [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.01 sec 69.9 KBytes 568 Kbits/sec 2 8.73 KBytes [ 5] 1.01-2.04 sec 0.00 Bytes 0.00 bits/sec 2 8.73 KBytes [ 5] 2.04-3.04 sec 0.00 Bytes 0.00 bits/sec 1 8.73 KBytes [ 5] 3.04-4.00 sec 0.00 Bytes 0.00 bits/sec 0 8.73 KBytes [ 5] 4.00-5.05 sec 0.00 Bytes 0.00 bits/sec 0 8.73 KBytes ^C[ 5] 5.05-5.82 sec 0.00 Bytes 0.00 bits/sec 1 8.73 KBytes - - - - - - - - - - - - - - - - - - - - - - - - - ifconfig ixl2.1011 mtu 8974 ifconfig BR_DCN_PF mtu 8974 iperf3 -c 192.168.11.42 Connecting to host 192.168.11.42, port 5201 [ 5] local 192.168.11.41 port 48630 connected to 192.168.11.42 port 5201 [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 120 MBytes 1.00 Gbits/sec 0 1.41 MBytes [ 5] 1.00-2.00 sec 118 MBytes 990 Mbits/sec 0 1.75 MBytes -- You are receiving this mail because: You are the assignee for the bug.
