I'm trying to use a Qnap dual port 2.5Gb NIC with FreeBSD 13.1.
FreeBSD recognizes the NIC and I'm able to connect to my LAN at
1Gb. However, trying to push heavy traffic through the NIC results
in a temporary loss of connectivity: traffic stops and the message
"igc0: link state changed to DOWN" appears in the system log. About
10 seconds later the message "igc0: link state changed to UP" is
logged, followed by some messages from dhclient indicating that it
has acquired a lease. At that point network connectivity works
normally, until I try to push a lot of traffic again. I've been
able to trigger this every time using iperf3 from another PC on my
LAN, and by using Ookla's speedtest client (my Internet service is
good for about 900 Mbps).
How long does it take to wedge the nic ? I have a pair of Topton
routers (4 IGC NICs) back to back and a simple iperf3 test seems to
work ok between the 2 units.
Actually, I was able to reproduce this too running iperf3 -P4 for
about 60 seconds. Watching via sysutils/ifstat, it does indeed drop
traffic when the link drops
ifstat -b
