Obviously, it's a bit different for x86_64 but that won't be running pre-10.6 so that's not a problem. The big difference for Ryan and me (10GbE driver authors) was the addition of mbuf_get_tso_requested() in 10.6 to support TSO. This is a critical feature for 10GbE (the difference between 5Gb/s at 100% CPU and 9.4Gb/s at moderate CPU usage) Having it as a separate function rather than as an extension to some extent function like mbuf_get_csum_requested() is frustrating because it makes a driver that wants to support TSO on 10.6 not loadable on 10.5 and 10.4. A question for the kext wizards: Is it possible to ship some kind of plugin that loads only on 10.4 and 10.5 which supplies a dummy mbuf_get_tso_requested() routine?
