Beaglebone black networking with latest 6 branch?

A few years ago I was able to bring up the RTEMS 6 branch and rtems-libbsd
on a beaglebone black. The ethernet device worked in this configuration.

I'm trying to update that code, so I cloned the latest rtems 6 branch and
the rtems-libbsd 6-freebsd-14 branch. Everything builds and RTEMS boots,
but the network devices don't seem to initialize. I need to take a closer
look at this, but there are messages about devices not being found in the
libbsd init code.
FreeBSD beaglebone notes have this:
 Tested 2024-04-02: 13.3-R boots, 14.X and 15.X do not. /phk

I tried building the rtems-libbsd 6-freebsd-13 branch, but it had
compilation errors - should that be used with an older commit of the rtems
6 branch?

How about Lwip? Does that work for the beagle? I would almost prefer that
for my application if it works.

Another option is the RPI4 - did anyone get that working with libbsd?

Thanks!
