I recently installed a Broadcom P425G (4x 25Gbe) on a hardware running OPNsense 23.1. Unfortunately, there seems to be a problem with the drivers and no ethernet card is shown (ifconfig -a). 

I should mention that on Linux the P425G Ethernet card works, and that on Linux I was able to install the latest P425G firmware [1].

OPNsense (13.1-RELEASE-p7) has a driver/module: if_bnxt.ko . With this module loaded, no network device is found. Furthermore, I tried to compile the latest version of the if_bnxt.ko module from [1]. Even after unload the bundled driver and loading the new driver, no Ethernet device was found.

Do you have any suggestion ?


Here a portion of the output of pciconf -lbcevV :
