[PATCH net-next] net: bridge: replace struct br_vlan_stats with pcpu_sw_netstats

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Struct br_vlan_stats duplicates pcpu_sw_netstats (apart from
br_vlan_stats not defining an alignment requirement), therefore
switch to using the latter one.
