Although I can imagine a significant number of CRC32 operations in high-capacity gateways (LTE gateways, IP core routers and so forth), Intel processors are not so prevalent in those areas (edit: anecdotal, of course, it's just my perception of the area. I'm a bit bored to seek concrete numbers on this. MIPS-based multicore processors seem to be more commonly used.). Still, there may be a significant benefit from hardware implementations of those operations (checksumming, hashing, Triple-DES/AES for IPsec, etc).
