Your initial premise seemed to include the offload of TCP
as well. Doesn't that mean:

application -> driver -> card [ creates full TCP/IP pkt ]

TCP is stateful, feature rich and highly configurable.
Do you expect that a fw/hw implementation will provide
an equivalent implementation? Support for tuning, options,
network taps, diag, bug fixes, feature tweaks, ... ?

Very curious..

thanks,
