I used an emulation testbed from Emulab.net with Dummynet traffic shaper
adding 100ms RTT
between two nodes, the link capacity is 1Gbps and both nodes are using
freebsd13.2.

I believe the default values for bce tx/rx pages are 2. And I happened to
find
this problem before that when the tx queue was full, it would not enqueue
packets
and started return errors.
And this error was misunderstood by the TCP layer as retransmission.
After adding hw.bce.tx_pages=3D4 and hw.bce.rx_pages=3D4 in /boot/loader.co=
nf
and reboot:
