    net: bridge: add support for per-port vlan stats · 9163a0fc
    Nikolay Aleksandrov authored
    This patch adds an option to have per-port vlan stats instead of the
    default global stats. The option can be set only when there are no port
    vlans in the bridge since we need to allocate the stats if it is set
    when vlans are being added to ports (and respectively free them
    when being deleted). Also bump RTNL_MAX_TYPE as the bridge is the
    largest user of options. The current stats design allows us to add
    these without any changes to the fast-path, it all comes down to
    the per-vlan stats pointer which, if this option is enabled, will
    be allocated for each port vlan instead of using the global bridge-wide
    one.
