Yes, it seems to be the case:
gem0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500
lladdr 00:11:24:87:a7:64
priority: 0
groups: egress
media: Ethernet autoselect (100baseTX full-duplex,rxpause,txpause)
status: active
inet 192.168.1.199 netmask 0xffffff00 broadcast 192.168.1.255
I have a crappy telco router, I’m actually not sure if I can disable it there.
There is a section on QoS, but the option is disabled.
Could the driver be forced to disable flow control? At least I could try
running it for a couple weeks to see if the bug is triggered again.
Thanks a lot,
Carlos
