Hi Sasha,

Thanks for mentioning this patch.  PS: For NVMe-oF TCP, the default behavior is that the header digest and data digest is not enabled. But definitely, if you enabled, with accelerated CRC32 function, it would be helpful.

Subject: [SPDK] CRC32 optimization for ARM platform

Hi,

Richael Zhuang from ARM submitted  CRC32 optimization for ARM:

https://review.gerrithub.io/c/spdk/spdk/+/437218

I tested  the patch and it significantly boosts NVME-OF TCP on ARM platform. Can we move forward with the patch and merge it into master?

Best regards

Sasha
