[haiku-development] Re: RTL8101/8102 FreeBSD Driver

As for dprintf: while debuggingsome other network driver I found out that
not all messages get written to /var/log/syslog after being emitted with
dprintf; I know that they're emitted because replacing the dprintf s with a
null pointer dereference makes the kernel panic.
