Hi Leonid
There you are you can use MDT as well, that's in Solaris 10 and 11,
for TCP and UDP, It's also in Solaris 9 but an older incarnation.
What's the MAX LSO your chip can do? If it has the common 64K
limit, then you would benefit from MDT as well. I agree about the
UDP market, it would be good to get the software interface for LSO into
Solaris as well, but for those who have hardware that hasn't got LSO
built in then they can use MDT, and for the Solaris install base which is
Solaris 10 now you can get the benefits of MDT in TCP/UDP now.
cheers
Frank
