Hi Darren
That would be UDP LSO right? Solaris 10 update 4 has
LSO for TCP, but not UDP. The key point I want to make here
is the adapter I'm working with has LSO for TCP also, the UDP
part it doesn't, yet, but no big deal because neither does Solaris.
I implemented MDT and it works for UDP and TCP and in a side
by side comparison of LSO v MDT, for TCP on the same card
MDT wins.
I want to get the Max performance for my adapter and Solaris
and presently MDT is proving the best way to do it. Having come
to this conclusion I thought I should share it with the alias, because
I need it to be maintained in Solaris, I was not expecting to hear
it was being EOL'd that's just premature.
