/proc/net/softnet_stat exists for a long time, but proc.rst miss it.
Softnet_stat shows some statistics of struct softnet_data of online
CPUs. Struct softnet_data manages incoming and output packets
on per-CPU queues. Notice that fastroute and cpu_collision in
softnet_stat are obsoleted, their value is always 0.
