I did measurements when implemented the patch and just retested once again
using pmcstat instruction and BR_MISP_RETIRED.ALL_BRANCHES counters.
With the patch applied the number of instruction events is 1% less and number
of mispredicted branch events is 5% less.

Hi Rick, Garret & others,
Thanks for the replies and useful info. I may take a look at enabling some
kernel module reloading, but, if the usual approach is rebooting, I expect
that this won't be an issue.
Regarding the NFS functionality itself, I can give a bit more of an overview

Hi,
thanks you all for the replies.
Unfortunately, the network chip is still not working and I updated the
PR (https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=197535) with the
last tests.
It seems that received packets are not transferred to mbuf or they are
transferred, but later, after the mbu

Oops.
The bug is with -h. If you remove -h you get the expected output
(except not humanized). I’ll fix it

We can't and don't plan to preserve the driver KPI for the 11 branch. We
actually plan to change it very much, in sake of keeping it stable there
on. Please see on what is going on in the projects/ifnet branch.
So, I'd suggest to intro

Hello FreeBSD,
Using natd it is possible to configure different "in_port" and "out_port"
and divert packets to necessary port for both directions.
Is there any way diverting a packet to in-kernel NAT
to give an advise in which direction packets src/dst addresses
should be translated?

Here's the scenario:
1) A small number of (Linux) clients run a large number of processes
(compute jobs) that read large files sequentially out of an NFS
filesystem. Each process is reading from a different file.
2) The clients are behind a network bottleneck.
3) The Linux NFS client will issue
So we have products coming soon that need to extend the media, if you have
grandiose plans in the future you can worry about things then, Linux can
handle the extended media TODAY, wouldn't it be nice to do so as well?
Also, this solution is something that can be MFC'd into 10 STABLE,
if you do so

Tbh, I respect Gleb's approach, but developing such a thing would take a
while; the fix Mike proposed would be a fix now.
I mean, I'd like to see a decoupling of media types and speeds from
"standard" names, and maybe have both an ability to query what modules a
device supports and what speeds it
