If this feature is negotiated, the driver must use the barriers suitable for hardware devices. Otherwise, the device and driver are assumed to be implemented in software, that is they can be assumed to run on identical CPUs in an SMP configuration. Thus a weaker form of memory barriers is sufficient to yield better performance. It is recommended that an add-in card based PCI device offers this feature for portability.

Thus extensions starting from DCTCPINFO cannot be requested directly. Some of them included into response unconditionally or hook into some of lower 8 bits. Extension INET_DIAG_CLASS_ID has not way to request from the beginning. This patch bundle it with INET_DIAG_TCLASS (ipv6 tos), fixes space reservation, and documents behavior for other extensions. Also this patch adds fallback to reporting socket priority. This filed is more widely used for traffic classification because ipv4 sockets automatically maps TOS to priority and default qdisc pfifo_fast knows about that. But priority could be changed via setsockopt SO_PRIORITY so INET_DIAG_TOS isn't enough for predicting class. Also cgroup2 obsoletes net_cls classid (it always zero), but we cannot reuse this field for reporting cgroup2 id because it is 64-bit (ino+gen). So, after this patch INET_DIAG_CLASS_ID will report socket priority for most common setup when net_cls isn't set and/or cgroup2 in use.
