My testbed has Nvidia/Mellanox/Chelsio 10GbE network cards which are quite old, but sit well in the price (super cheap) usability (they work great on FreeBSD ond Linux) spectrum.
There is an issue on FreeBSD 14 -CURRENT where when you load the kernel module
for the card (mlx4en)
hangs. If you hit control C the process will
continue and the module will load properly. This is also an issue when you
load the module using
and as my router machine can't be
managed with serial yet I have no way to press control C when it is booting.
On the bug report I was asked if the firmware is up to date. It wasn't and doing so was not fun.
You should follow the Mellanox instructions rather than my blog post to do a firmware update, but The Mellanox FreeBSD documentation for ( Linux ) the cards is from 2015 and this is the process that worked for me in 2021.
Mellanox have a tools package you can download, there is also a port called
you can install:
# pkg install mstflint
The Mellanox tools need to know which card they are speaking to, you can find
the card with
once you have loaded the kernel module:
# pciconf -lv | grep mlx4 mlx4_core0@pci0:9:0:0: class=0x020000 rev=0x00 hdr=0x00 vendor=0x15b3 device=0x1007 subvendor=0x15b3 subdevice=0x000c
Downloading the firmware for card required a OPN and a PSID from the card. You
to get information about the card with the pci address and
the 'q' query command:
# mstflint -d pci0:9:0:0 q Image type: FS2 FW Version: 2.40.5030 FW Release Date: 4.1.2017 Product Version: 02.40.50.30 Rom Info: type=PXE version=3.4.746 Device ID: 4103 Description: Node Port1 Port2 Sys image GUIDs: ffffffffffffffff ffffffffffffffff ffffffffffffffff ffffffffffffffff MACs: ec0d9ae13420 ec0d9ae13421 VSD: PSID: MT_1200111023
This didn't give me an OPN so instead I looked at every entry on the download page until I found the correct PSID.
With the firmware downloaded and unzipped you can flash it using
# mstflint -d pci0:9:0:0 -i fw-ConnectX3Pro-rel-2_42_5000-MCX312B-XCC_Ax-FlexBoot-3.4.752.bin b Current FW version on flash: 2.40.5030 New FW version: 2.42.5000 Burning FS2 FW image without signatures - OK Restoring signature - OK
