Me too. Now I'm writing my version of mervell yukon2 driver, which has partial checksum and lso capabilities. When I want to use both of partial checksum and lso, mss value of lso packets which hcksum_retrieve() returned seemed partial checksum, instead of mss. I also use lso for realtek816x and nVIDIA integrated nics, which have full checksum and lso capabilities. They work well for me. -masa > _______________________________________________ driver-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/driver-discuss
