Some Intel NICs (at least the 10G ones, but some Googling suggests some 1G as well) support SCTP checksum offload. Also, the checksum is a CRC32C and the SSE4.2

Some Intel NICs (at least the 10G ones, but some Googling suggests some 1G as well) support SCTP checksum offload. Also, the checksum is a CRC32C and the SSE4.2 CRC32 instruction can calculate these really fast.
