This means dpdk21.08 & dpdk21.11 supports "Arkville 21.05", right? And what exactly "Arkville 22.07" represents, I assume it is a package distributed by Arkville. Is the "Arkville 22.07" information enough, or is there any benefit to document required FW versions? Also can you please update release notes that device FW(s) needs to be updated to "Arkville 22.07". ^ permalink raw reply [flat|nested] 49+ messages in thread
