Hello,

what NIC are you using? And with what type of connection (RJ-45, SFP, Twinax)?

I updated NIC driver from 3.2.12-k to 3.2.18 and
set mtu to 9000 and
hw.intr_storm_threshold=0

I will report what will happen next.

Do you use DHCP client to get IP address for this interface? If so, take a look
at https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=229432 for a workaround
and solution.

You didn't report on what happened after updating. Did anything change?

Now I use FreeBSD 11.2-RELEASE-p4 and 3.2.18 ix0 driver from official website.
I don't see any problems. I think is everything is OK.

Worth noting that Intel also provides its upstream ix driver [1] via
ports/packages. See https://www.freshports.org/net/intel-ix-kmod/ (currently
3.3.6).

[1] And em, ixl drivers via intel-em-kmod / intel-ixl-kmod
