One exception is SOCKLND on Chelsio's T3, quote:

"The T3 ASIC uses the mechanism of Direct Data Placement (DDP)  that
provides a flexible zero copy on receive capability for regular TCP
connections, requiring no changes to the sender, the wire protocol, or
the socket API on sending or the receiving side."

I remembered that a small SOCKLND fix was landed recently to make use
of this zero copy receive capability.
