[rescue] Fix for 3Com 2500 NFS Problems with Solaris Host

I know a couple people here ran into the same problem as I did when 
accessing FDDI NFS hosts from ethernet when using a 3Com 2500 as 
their switch. In order to fix the problem, one must add "ndd -set 
/dev/ip  ip_path_mtu_discovery 0" to "/etc/init.d/inetinit". This 
info comes courtesy of a post made by Peter Eriksson. The logic 
behind it is that the Sun tells the 3Com not to do IP fragmentation 
which leads to problems when switching from the 4500 to 1500 byte 
MTUs. I assume Linux does the same thing which is why clients have 
trouble connecting to it.
