I suppose this could have been configured in libbsd (possibly config.inc) instead if that's what you're getting at. The overall goal is to be able to run the tests that use the network on any one of the board variants that this BSP supports. My takeaway from the earlier conversation on the list is that this was the preferred method of switching the ethernet interface for those tests.

Hi,

I am just catching up and missed this one until I saw the patch was pushed. I am
sorry but I am confused by this patch.

Could someone please explain this reason for this addition to the BSP and
approach being taken? Is there something in the BSP that requires this
information be provided here?

Provide the options necessary to enable any combination of CGEM ethernet
interfaces in LibBSD. The default is still CGEM3, so this should
continue to operate as expected on typical Zynq Ultrascale+ MPSoC
development hardware.
