Sorry for the lack of info.
I followed the directions to disable modules, uninstall the default drivers and install the provided mellanox driver in post #169. I'd like to bring my ESXi back to default, presumably by uninstalling the provided driver and installing the default drivers/enabling modules.
I haven't been able to figure out how to do this... I basically tried to do what was laid out in your post, in reverse, but that didn't work. It asked me for a depot, that's where I got lost. I tried googling, but this is my first foray into ESXi in my homelab setting and my google skills are failing me.
Yes, the card is listed in devices, but is not appearing in the list of physical NICs.
Thanks for your help.
Edit: I managed to uninstall all of the individual Mellanox drivers. Now I'm just not sure which to install so that future updates to ESXi will be seamless.
