Title: [Tutorial] Compile network driver
Post by: d3pr3cat3d on February 14, 2021, 08:39:42 pm

This tutorial is how to compile and install the latest Intel if_em.ko driver, this may work for other drivers that you want to compile?

The right way is to use a OPNsense version that is the same version that you are using in production.

Thanks to almodovaris for pointing this out.

I found an old topic from franco that explained how to do this in OPNsense.

Prior to finding franco's post I ran in to this error while trying to compile the driver.

Code: [Select]

root@OPNsense:/tmp/em-7.7.8/src # make
make: "/usr/share/mk/bsd.kmod.mk" line 16: Unable to locate the kernel source tree. Set SYSDIR to override.
This my process for OPNsense version 21.1. I was using Arch Linux and running OPNsense as a VM using KVM with libvirt. The driver was copied to /tmp on the OPNsense VM.

If you installed the GITWEB option please follow these instructions:

In the directory /usr/local/share/examples/git/gitweb you can find all files to
make gitweb work as a public repository on the web.

All you have to do to make gitweb work is:
1) Please be sure you're able to execute CGI scripts in
   /usr/local/share/examples/git/gitweb.
2) Set the GITWEB_CONFIG variable in your webserver's config to
   /usr/local/etc/git/gitweb.conf. This variable is passed to gitweb.cgi.
3) Restart server.


If you installed the CONTRIB option please note that the scripts are
installed in /usr/local/share/git-core/contrib. Some of them require
other ports to be installed (perl, python, etc), which you may need to
install manually.

There are two files that you want to copy to your production OPNsense system, /tmp/em-7.7.8/src/em.4 and /tmp/em-7.7.8/src/if_em.ko

I copied them to /root.

Copy the man page to the proper directory

Code: [Select]

# gzip -c em.4 > /usr/share/man/man4/em.4.gz
When I copied the if_em.ko driver to /root I changed the name to if_em.ko-OPNsense-21.1v7.7.8 we need to put this in the right place now.

Edit/Update 1
The user DimitriDC posted a link below witch lead to user Franco posting the correct location to put the driver, it should be placed in /boot/modules/

Code: [Select]

cp if_em.ko-OPNsense-21.1v7.7.8 /boot/modules/if_em_updated.ko
Edit /boot/load.conf.local to contain the line:

Code: [Select]

if_em_updated_load="YES
Reboot and test.

Code: [Select]

# kldstat | grep update
12    1 0xffffffff82956000    67bd8 if_em_updated.ko

Hello,

thanks for the nice tutorial, when I followed it I ended up in the message.

cannot register pci/em from kernel: already loaded from if_em.ko
pci/em failed to register: 17

Any chance that the onboard intel® ethernet connection i219-v could be used ?

Title: Re: [Tutorial] Compile network driver
Post by: Gary7 on August 08, 2021, 07:36:31 pm

As an experiment on my home OPNsense firewall, I compiled the updated Intel network drivers for my APU2 system (I210 NIC)

Intel® Network Adapter Gigabit Base Driver for FreeBSD
   version 7.7.8   released 04/07/2020
Intel® Network Adapter Driver for 82575/6 and 82580-Based Gigabit Network Connections under FreeBSD
   Version 2.5.19   released 07/21/2021

I followed the instructions in this tutorial:
   pkg install git
   git clone plugins, ports, & src
   compiled both drivers

Everything went smoothly.
Copied if_igb.ko and if_em.ko to /boot/kernel (renamed the original files for backup)
Modified /boot/loader.conf.local: #if_em_load="YES" & if_igb_load="YES"
If loading the if_igb.ko driver failed, I could modify loader.conf.local to load if_em.ko and reboot again.

Rebooted and everything appeared to start normally. "if_igb.ko" was loaded without error.
Using kldstat, I verified that "if_igb.ko" was being used: 14    1 0xffffffff82968000    397a8 if_igb.ko

So far, networking on my firewall is working normally without error.
Now, some "hw.igb" tuning variables are available ( sysctl hw.igb ).
Performance appears to be normal. I still get my full ISP speed, 200+ Mbps.

I also see that the igb driver is smaller.
   if_igb.ko   223272 bytes
   if_em.ko   407664 bytes

Sharing my experience.
