Mellanox ConnectX-2 pfSense Drivers
Pre-Compiled Kernel Modules for Mellanox ConnectX-2 / pfSense 2.4.4
For whatever reason, the drivers for this (very cost-effective) 10GBit SFP+ expansion card are not included in pfSense. Additionally, pfSense does not include the necessary compiler to build these modules from source.
To get the ConnectX-2 working under pfSense, I had to build the kernel modules for it from source on a separate FreeBSD 11 machine. To potentially save someone else this hassle, I've decided to upload these pre-compiled kernel modules to GitHub.
- Unzip the
Mellanox.zipfile (under Releases) somewhere on your pfSense host.
- Copy all of the
*.kofiles within to /boot/kernel/
chmod 555 /boot/kernel/ml*.koand
chmod 555 /boot/kernel/linuxkpi.koto ensure the new modules have the proper permissons.
kldload mlx4ento load the module - after doing this, pfSense should detect the card as a new interface
- After making sure the driver works properly, edit
mlx4en_load="YES"to load the driver on boot.
- Tested on pfSense 2.4.4 (FreeBSD 11.2-RELEASE-p3) amd64
- I cannot guarantee this will be compatible with your system, but it should work on any pfSense release based on FreeBSD 11
- Tested with Mellanox ConnectX-2 but this set of kernel modules should also support the ConnectX-3 and ConnectX-4. To enable ConnectX-4 support, you'll probably have to change
