I just installed, updated to FreeBSD-current amd64, and still have the problem that kept me away from FreeBSD 12.x.

I would like to try this port, install on two computers.

Both have problematic (with FreeBSD, not NetBSD, OpenBSD or Linux) re Ethernet; one more severe than the other.

I'd like to compile on the less severely affected computer, perhaps install there and surely install on the more severely affected computer.

Would I just copy the module to the second computer, which would be running NetBSD, using NFS?
