Note:I'm still waiting to get the definitive PCI ID of this NIC, but it looks
like one we support (8111C, Windows lists it as Realtek RTL8168C/8111C)
The NIC fails to operate using IPHardware Checksum Offloading, rendering the
card useless unless ip:dohwcksum=0 is set in /etc/system.
Traffic other than TCP/UDP (that is, ICMP) works, so it looks like the card
is functioning properly, while in fact it doesn't. Difficult to diagnose
problem for end-users.
Work Around
add
set ip:dohwcksum = 0
to /etc/system
This doesn't appear to be a successful workaround in all cases according to internet reports on OpenSolaris.ORG http://opensolaris.org/jive/thread.jspa?threadID=91282
Comments
This is being seeing by various people using Intel mother boards, both Atom and Intel Core i7 based. Murayama has produced a driver (gani) which works for the RealTek 8111C chip, but it would be very good for consumer support to have Solaris natively work on this chip. A good roll-up of the various "hey my network is broken!" discussions is available at: http://sigtar.com/2009/02/12/opensolaris-rtl81118168b-issues/
