We've spoken to at least one small NIC vendor that puts ~48GB of RAM on their FPGA based smart nic. That let's them handle TCP rexmits without paying the price of re-DMA'ing data from the host to re-encrypt it. I wish the FPGA didn't blow our power budget, because their solution would be ideal for P2P DMA.
