I asked the question below a while back but got no answer. Does that mean BCM5754 integrated GbE will not be supported by 6.2 release at all? The HARDWARE.TXT file does not list it, but the source code seems to have the BCM5754 support, or at least so the CVS comments say. Does anyone know when if_bge will support BCM5754 GbE? We really hope to run FreeBSD on our Dell Precision desktops. Thanks in advance!
