https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D268490 --- Comment #49 from Santiago Martinez <sm@codenetworks.net> --- Hi Daniel,=20 from the config posted seems to be diff,but maybe i miss understood the fir= st msg.Anyhow the behavior that Marek is describing is not limited only to tho= se cards. You can increase the MTU on the phy or reduce the mtu on the logical= .=20 I can see the same issue with IXL, BNXT and so on. This is an output from my lab machines. ixl2: flags=3D8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0= mtu 9000 ixl2.1011: flags=3D8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> met= ric 0 mtu 9000 BR_DCN_PF: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mt= u 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=20= =20=20=20=20=20=20 [ 5] 1.01-2.04 sec 0.00 Bytes 0.00 bits/sec 2 8.73 KBytes=20=20= =20=20=20=20=20 [ 5] 2.04-3.04 sec 0.00 Bytes 0.00 bits/sec 1 8.73 KBytes=20=20= =20=20=20=20=20 [ 5] 3.04-4.00 sec 0.00 Bytes 0.00 bits/sec 0 8.73 KBytes=20=20= =20=20=20=20=20 [ 5] 4.00-5.05 sec 0.00 Bytes 0.00 bits/sec 0 8.73 KBytes=20=20= =20=20=20=20=20 ^C[ 5] 5.05-5.82 sec 0.00 Bytes 0.00 bits/sec 1 8.73 KBytes=20= =20=20=20=20=20=20 - - - - - - - - - - - - - - - - - - - - - - - - - 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=20= =20=20=20=20=20=20 [ 5] 1.00-2.00 sec 118 MBytes 990 Mbits/sec 0 1.75 MBytes --=20 You are receiving this mail because: You are the assignee for the bug.=
