I've encountered a problem with NetBSD current (not CVS, released) and the 
SIS 900 series Ethernet chipset.  NetBSD correctly identifies the PHY, sets 
up the interrupt, etc.  A ping from an outside machine to the NetBSD machine 
works correctly.  However, packets originating on the NetBSD machine appear 
to be garbled (speculation) and "packet size exceeded" errors are reported 
(fact).  The error says that the packet size is between 2300 and 2400 bytes, 
not always the same value but always within these limits.  (The network is 
your usual 10/100 ethernet with an MTU of about 1500 bytes.)

If this is not a known problem I'll track it down.  If it is a know problem, 
please let me know.  I checked the bug database but I'm not confident that 
I'm sufficiently conversant with it (the bug database, that is) to be sure 
that there really isn't anything there.

TIA,
