MengjinWu 7fc2c0856e lib/nvmf: use DSA to offload recv data digest crc32 in nvmf-TCP ... allow DSA device to async offload crc32 calculation in nvmf-TCP This patch can use DSA to accelerate crc32 computation, making the io performance of TCP paths using crc32 approach the io performance of TCP paths that do not use crc32. Using SLIST to minimize the performance drop. SLIST has less operation compared to TAILQ. Thinking about memory thrashing, we should use the same memory as possible to receive new PDUs. So, insert newly freed PDU in to head is better. The performance drop is within 1% compared to the TCP path without crc32.
