Recent changes in Linux kernel TC action subsystem introduced new TCA_ACT_FLAGS_NO_PERCPU_STATS flag. The purpose of the flag is to request action implementation to skip allocating action stats with expensive percpu allocator and use regular built-in action stats instead. Such approach significantly improves rule insertion rate and reduce memory usage for hardware-offloaded rules that don't need benefits provided by percpu allocated stats (improved software TC fast-path performance). Set the flag for all compatible actions. Modify acinclude.m4 to use OVS-internal pkt_cls.h implementation when TCA_ACT_FLAGS is not defined by kernel headers and to manually define struct nla_bitfield32 in netlink.h (new file) when it is not defined by kernel headers.

* value = 0x0, and selector = 0x1
|
|
* implies we are selecting bit 1 and we want to set its value to 0.

|
