I entirely agree with you.  Thanks for the note.  It looks like vpn has
incorporated the change regarding CHECKSUM_HW:

+// With linux 2.6.19, they renamed CHECKSUM_HW to CHECKSUM_COMPLETE
+#if LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,19)
+  #define CHECKSUM_HW CHECKSUM_COMPLETE
+  #define SKB_CHECKSUM_HELP(a,b)	skb_checksum_help((a))
+#else
+  #define SKB_CHECKSUM_HELP(a,b)	skb_checksum_help((a),(b))
+#endif

Hope vmware provides a fix so that we do not have to adjust the kernel
file each time it is updated.
