Years ago, the hunt for the cheapest 10gbe NICs resulted in buying Mellanox ConnectX-2 single-port 10gbe network cards from eBay for around $10. Nowadays those cards have increased in cost to around $20-30. While still cheap, not quite the cheapest. There are now alternatives!
Before diving into details, let’s get a something very clear. If you want the absolute simplest plug-and-play 10gbe LAN for your homelab, pay the extra for Mellanox. If you’re willing to go hands-on, do some simple manual configuration and installation, read on for my experiences with Emulex 10gbe NICs.
Emulex NICs can often be had for around $15 on eBay, sometimes even cheaper. I recently picked up a set of 4 of these cards, which came bundled with 6 SFP+ 10g-SR modules for a grand total of $47.48. Considering I can usually find SFP+ modules for about $5/ea, these alone were worth $30.
Card model numbers to look out for
- Emulex OCE10102
- Emulex OCE11102
- HP NC550SFP
- IBM 49Y7952
- IBM 96Y3766
FreeNAS 11.3
FreeNAS is the easiest OS to work with. These cards will work out of the box with the latest driver back-ported from FreeBSD 13-CURRENT, and enabled by default. Just put the card in, and configure like you would any other NIC on FreeNAS.
FreeBSD 12.1-RELEASE
FreeBSD 12 includes the latest driver, much like FreeNAS, however it is not enabled to load automatically. One small file edit is all this will take! Add the following line to your /boot/loader.conf
file.
root@OPNsense:~ # echo 'if_oce_load="YES"' >> /boot/loader.conf
After that, reboot, and configure your NIC like normal.
FreeBSD 11.2-RELEASE
If all you want is basic network connectivity and VLAN support, simply follow the directions above for FreeBSD 12.1-RELEASE. However, do note that this FreeBSD releases uses an outdated driver that does not work with features such as CARP.
FreeBSD 11.3-RELEASE and FreeBSD 11.4-RELEASE
These versions of FreeBSD include a broken version of the Emulex oce(4) driver. SOME cards will work, SOME cards will cause a kernel panic initializing the driver. Please continue reading on for details on custom compiling the Emulex oce(4) driver.
If you’re already experienced at compiling and implementing FreeBSD driver changes, simply head over to this commit for the patch.
https://github.com/freebsd/freebsd/commit/b44d7086a16f737935e1eec7c7995adbc077081e
OPNsense 20.1 and HardenedBSD 11.2-RELEASE
These OSes come with the same driver included with FreeBSD 11.2-RELEASE. Out of the box, the driver has basic networking and VLAN functionality, but is also disabled by default, and also lacks support for advanced networking features like CARP. If you don’t need the more advanced networking features, simply follow the instructions above for FreeBSD 12.1-RELEASE to enable the Emulex oce(4) driver at boot.
If you want the quick and easy solution, I’ve provided the pre-compiled binary for the patched driver at the following URL. https://vincerants.com/public/opnsense/if_oce.ko

Custom Compiling the Emulex oce(4) Driver – Prepping the /usr/src Tree
Because my intended use case for these NICs are a series of OPNsense routers, this part of the guide is going to be custom tailored for building the driver natively on this OS.
First, install nano
for easier text file editing. Next, enable the FreeBSD package repository. Use this repository to install git
so that way we may clone the source tree.

Message from freetype2-2.10.1:

The 2.7.x series now uses the new subpixel hinting mode (V40 port's option) as
the default, emulating a modern version of ClearType. This change inevitably
leads to different rendering results, and you might change port's options to
adapt it to your taste (or use the new "FREETYPE_PROPERTIES" environment
variable).
The environment variable "FREETYPE_PROPERTIES" can be used to control the
driver properties. Example:
FREETYPE_PROPERTIES=truetype:interpreter-version=35 \
cff:no-stem-darkening=1 \
autofitter:warping=1
This allows to select, say, the subpixel hinting mode at runtime for a given
application.
If LONG_PCF_NAMES port's option was enabled, the PCF family names may include
the foundry and information whether they contain wide characters. For example,
"Sony Fixed" or "Misc Fixed Wide", instead of "Fixed". This can be disabled at
run time with using pcf:no-long-family-names property, if needed. Example:
FREETYPE_PROPERTIES=pcf:no-long-family-names=1
How to recreate fontconfig cache with using such environment variable,
if needed:
# env FREETYPE_PROPERTIES=pcf:no-long-family-names=1 fc-cache -fsv
The controllable properties are listed in the section "Controlling FreeType
Modules" in the reference's table of contents
(/usr/local/share/doc/freetype2/reference/site/index.html, if documentation was installed).

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.

|Subject: [PATCH] Fix array out of bound panic introduced in r306219.
|
|As I see, different NICs in different configurations may have different
|numbers of TX and RX queues. The code was assuming 1:1 mapping between
|event queues (interrupts) and TX/RX queues. Since number of interrupts
|is set to maximum of TX and RX queues, when those two are different, the
|system is doomed.
|
|I have no documentation or deep knowledge about this hardware, so this
|change is based on general observations and code reading. If some of my
|guesses are wrong, please do better. I just confirmed HP NC550SFP NICs
|are working now.

Custom Compiling the Emulex oce(4) Driver – Installing the Driver
With the driver built the only thing left to do is install it on the system. Copy the driver to the /boot/kernel/
folder and enable the driver in /boot/loader.conf
