The SPDK libraries are mostly storage-specific components (the I/OAT DMA engine can be used for generic copy offload, but it is particularly useful for copying between network and storage buffers). SPDK itself does not provide any network functionality.
I am not familiar enough with the Xeon Phi or GPU programming model to say for sure, but they could possibly be used to offload tasks like hashing/dedup or other storage-related functions.
