Perhaps a difference between 9.2 and 10 for one of the macros?  My code is:

ifp->if_hw_tsomax = IP_MAXPACKET - (ETHER_HDR_LEN + ETHER_VLAN_ENCAP_LEN);
        printf("CSF - 3 Init, ifp->if_hw_tsomax = %d\n", ifp->if_hw_tsomax);

(BTW, you should submit the hw_tsomax sysctl patch, that's useful to others)

Oh, I thought it was giving every packet that is greater than or equal to
65518 - Could you show me the proper command? That's the third time I've
used dtrace, so I'm making this up as I go. :-)
