Hi Hooman
Here is what I've got when the script triggered just in time when the
interface was locked

What device is at the other end of link?
Just a simple soho router/switch/wifi AP. I use it as a gigabit switch
with dot1q support and wifi AP.
It's management capabilities and features are very limited. Here is what
I've got form the switch info, it's rather obscure, for ex. I have no
idea what does Dot3StatsFCSErrors means. But at least I had no problems
with this switch and another nic which is nvidia LOM running nfe driver

The input errors netstat reports correspond to the missed_packets
reported by the driver.
Also the driver has been OACTIVE when the problem occurred.
There are also a strange number of xon/xoff frames transmitted and
received by the driver.
You may try these settings and see if they help:
- hw.em.fc_setting=0 (in /boot/loader.conf)
- hw.em.rxd="4096" (in /boot/loader.conf)
- hw.em.txd="4096" (in /boot/loader.conf)
- Fix speed and duplex at both link sides. After doing that, confirm
on the freebsd
box (with ifconfig) and the other device (with whatever command it
provides) that
the same speed and duplex is used by both devices.
Thanks for taking a look at this and for the tips, I'll do the changes
and will see if this helps.
you also have high values for dev.em.0.rx/tx_[abs]_int_delay. If you
have set them manually, remove them or replace them with these in
loader.conf:
hw.em.rx_int_delay=0
hw.em.tx_int_delay=66
hw.em.tx_abs_int_delay=66
hw.em.rx_abs_int_delay=66
Yes, indeed it was my blind tuning trying to change anything here and
there because of those locks. Will remove this to the default.
