Of particular note was the contributions of patches to fix NFS race conditions. Plus tools to stress and duplicate those conditions.

Believe a number of FreeBSD drivers made it into MacOS X. Don't know of any Apple product which used Intel Etherexpress Pro chipsets but I popped a PCI card in a Mac one day and it magically worked as if it had always been there.
