Hi, According to the section 22.3.6 Available kernel drives in https://doc.dpdk.org/guides-21.11/cryptodevs/qat.html?highlight=qat , the "Driver/ver" column for device C4xxx is still in release pending status. Yes No No 3 C4xxx p qat_c4xxx c4xxx 18a0 1 18a1 128 Does it mean that DPDK still cannot run acceleration with QAT C4xxx device? If it can, how does it work? Thanks Changchun
