Title: Infiniband as Network interface?
Post by: studiofunk on March 21, 2019, 01:03:18 PM

Hi there,

we have a few Mellanox Infiniband interfaces (MCX354A-FCBT) and would love to get the 40G speed into our OPNsense system.
Anything possible?

I just found that the mlx4en driver is available. not the mlx4ib.

Could I get this to work somehow?

Best regards,
Thomas

I compiled it years ago for pfSense 2.1 but didn't touched it yet again.
Infiniband and FreeBSD isn't really funny, you should stick to en where possible.

With the sources package from FreeBSD 11.2 it's not a problem...

fetch ftp://ftp.freebsd.org/pub/FreeBSD/releases/amd64/11.2-RELEASE/src.txz
tar -C / -xvzf src.txz

echo '#!/bin/sh -e' > ofed_install.sh
echo -en '\n' >> ofed_install.sh
echo 'cd /usr/src/sys/modules' >> ofed_install.sh
echo 'for module in mlx4 ibcore mlx4ib ipoib; do ' >> ofed_install.sh
echo ' cd $module' >> ofed_install.sh
echo ' make' >> ofed_install.sh
echo ' make install' >> ofed_install.sh
echo ' sync' >> ofed_install.sh
echo ' kldload $module || true' >> ofed_install.sh
echo ' printf "${module}_load=\"YES\"\n" >> /boot/loader.conf.local' >> ofed_install.sh
echo ' cd ..' >> ofed_install.sh
echo 'done' >> ofed_install.sh
echo 'kldstat' >> ofed_install.sh
