Yes, and ? These are un-related stacks.

Some highend DAC/ADC have high speed serial interfaces and
encode/packetize the data before sensing them to the CPU/FPGA/ASIC
that will deal with the samples, would you consider that a PHY
emulation as well ? The way the samples are transported from one
endpoint to the other is largely irrelevant here ...
