Neterion x3100 10GbE ASIC supports UDP LSO in hardware (x3100 is announced but not generally available yet).
Shipping Xframe-II and Xframe-E 10GbE NICs support somewhat different version of hw UDP offload (known as UFO :-)); currently it is productized in Linux and some other OSes, but not in Solaris. Overall, expanding Solaris LSO to support UDP (in addition to TCP) will be very worthwhile; we can help to debug and get it working as soon as Solaris stack code is ready. UDP market is likely to grow (due to video streaming market, and general improvement in datacenter Ethernet); having generic TCP/UDP LSO support will be a good thing.
