[PATCH v4 05/10] examples/l3fwd: use accelerated CRC on riscv

[Daniel Gregory]

From: Daniel Gregory <daniel.gregory at bytedance.com>

When the RISC-V Zbc (carryless multiplication) extension is present, an
implementation of CRC hashing using hardware instructions is available.
Use it rather than jhash.
