some advice?

Did you perform the step where you unbind from the sf config driver and bind to the mlx5_core.sf driver?

ex)

echo mlx5_core.sf.4  > /sys/bus/auxiliary/drivers/mlx5_core.sf_cfg/unbind
echo mlx5_core.sf.4  > /sys/bus/auxiliary/drivers/mlx5_core.sf/bind

Also, you’ll need en3f0pf0sf4 to be trusted. en3f0pf0sf5 is already trusted.

I hadn’t done the “unbind” and “bind” operations and I forgot to set “trust” en3f0pf0sf4.
Thank you.

URL FILTER>>

is it working correctly now?

4

Yes it looks like it’s started up. The URL filter application is interactive like this. The docs show you how to create, compile and apply rules.

I got this error “bash: echo: write error: No such device”.
