2019-01-24bonding: count master 3ad stats separatelyNikolay Aleksandrov
I made a dumb mistake when I summed up the slave stats, obviously slaves can come and go which would make the master stats unreliable. Count and export the master stats separately.

2019-01-22bonding: add support for xstats and export 3ad statsNikolay Aleksandrov
This patch adds support for extended statistics (xstats) call to the bonding. The first user would be the 3ad code which counts the following events: - LACPDU Rx/Tx - LACPDU unknown type Rx - LACPDU illegal Rx - Marker Rx/Tx - Marker response Rx/Tx - Marker unknown type Rx All of these are exported via netlink as separate attributes to be easily extensible as we plan to add more in the future. Similar to how the bridge and other xstats exports, the structure inside is: [ IFLA_STATS_LINK_XSTATS ] -> [ LINK_XSTATS_TYPE_BOND ] -> [ BOND_XSTATS_3AD ] -> [ 3ad stats attributes ] With this structure it's easy to add more stat types later.

2019-01-22bonding: add 3ad statsNikolay Aleksandrov
Count the following types of 3ad packets per slave: - rx/tx lacpdu - rx/tx marker - rx/tx marker response - rx illegal lacpdus (right now counted on wrong length) - rx unknown lacpdu type - rx unknown marker type The counters are using atomic64 since this is not fast path.

2016-02-09bonding: 3ad: apply ad_actor settings changes immediatelyNikolay Aleksandrov
Currently the bonding allows to set ad_actor_system and prio while the bond device is down, but these are actually applied only if there aren't any slaves yet (applied to bond device when first slave shows up, and to slaves at 3ad bind time). After this patch changes are applied immediately and the new values can be used/seen after the bond's upped so it's not necessary anymore to release all and enslave again to see the changes.

2015-11-02bonding: simplify / unify event handling code for 3ad mode.Mahesh Bandewar
Old logic of updating state-machine is not required since ad_update_actor_keys() does it implicitly. The only loss is the notification differentiation between speed vs. duplex change. Now only one unified notification is printed. Signed-off-by: Mahesh Bandewar <maheshb@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-02-24bonding: Implement port churn-machine (AD standard 43.4.17).Mahesh Bandewar
The Churn Detection machines detect the situation where a port is operable, but the Actor and Partner have not attached the link to an Aggregator and brought the link into operation within a bound time period. Under normal operation of the LACP, agreement between Actor and Partner should be reached very rapidly. Continued failure to reach agreement can be symptomatic of device failure.
