How to compile and install latest realtek network driver in pfSense 2.4.x (FreeBSD 11.1)

1. Download FreeBSD 11.1 VMDK and create a VM with it as HDD.

2. Get FreeBSD source tree for your exact FreeBSD version and uncompress it to /usr/src:

   fetch -o /tmp ftp://ftp.freebsd.org/pub/`uname -s`/releases/`uname -m`/`uname -r | cut -d'-' -f1,2`/src.txz
   tar -C / -xvf /tmp/src.txz
   

3. Download latest Realtek network driver (you need to input an email address).

4. Uncompress driver:

   tar xvzf 0007-rtl_bsd_drv_v194.01.tgz
   

5. Make driver:

   cd rtl_bsd_drv_v194.01
   make
   

   1. If the last command fails, change the following line in file if_re.c

      From: #include <dev/re/if_rereg.h>

      To: #include "if_rereg.h"

6. Copy the file if_re.ko to the /boot/kernel folder in pfSense device.

   scp if_re.ko root@<pfSense device IP>:/boot/kernel

7. Change file permissions in if_re.ko file accessing through SSH to pfSense.

   chmod 555 /boot/kernel/if_re.ko

8. Modify /boot/loader.conf.local file and add the following line at the end of the file: if_re_load="YES"

   • Through console: vi /boot/loader.conf.local
   • Through web: Diagnostics > Edit File and click Load. When finished editing click Save.

9. Reboot pfSense.

10. After restart, verify if module is installed through ssh with kldstat. Example execution:

    [2.4.2-RELEASE][root@pfSense.local]/root: kldstat
        Id Refs Address            Size     Name
         1    7 0xffffffff80200000 2c3ea98  kernel
         2    1 0xffffffff82e3f000 80900    if_re.ko
         3    1 0xffffffff83021000 46c6     cryptodev.ko

For future users:
You can just search package using this command: pkg search realtek-re-kmod, and this output will like to this:

realtek-re-kmod-198.00_3       Kernel driver for Realtek PCIe Ethernet Controllers

Then you can install using following command: pkg install realtek-re-kmod-198.00_3

And follow package's message.

In my case, Realtek provided source is broken to build in FreeBSD 14.
