net: unify the pcpu_tstats and br_cpu_netstats as one
They are same, so unify them as one, pcpu_sw_netstats. Define pcpu_sw_netstat in netdevice.h, remove pcpu_tstats from if_tunnel and remove br_cpu_netstats from br_private.h Cc: Cong Wang <xiyou.wangcong@gmail.com> Cc: Stephen Hemminger <stephen@networkplumber.org> Signed-off-by: Li RongQing <roy.qing.li@gmail.com> Signed-off-by: David S.
