net: bridge: add support for per-port vlan stats

2018-10-12T17:18:58+00:00

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.

net: bridge: convert mcast options to bits

2018-09-26T17:04:23+00:00

This patch converts the rest of the mcast options to bits. It also packs the mcast options a little better by moving multicast_mld_version to an existing hole, reducing the net_bridge size by 8 bytes. Signed-off-by: Nikolay Aleksandrov Reviewed-by: Stephen Hemminger Signed-off-by: David S. Miller

net: bridge: convert and rename mcast disabled

2018-09-26T17:04:23+00:00

Convert mcast disabled to an option bit and while doing so convert the logic to check if multicast is enabled instead. That is make the logic follow the option value - if it's set then mcast is enabled and vice versa. This avoids a few confusing places where we inverted the value that's being set to follow the mcast_disabled logic.

net: bridge: add bitfield for options and convert vlan opts

2018-09-26T17:04:22+00:00

Bridge options have usually been added as separate fields all over the net_bridge struct taking up space and ending up in different cache lines. Let's move them to a single bitfield to save up space and speedup lookups. This patch adds a simple API for option modifying and retrieving using bitops and converts the first user of the API - the bridge vlan options (vlan_enabled and vlan_stats_enabled).
