bonding: 802.3ad: make aggregator_identifier bond-private
[ Upstream commit 163c8ff30dbe473abfbb24a7eac5536c87f3baa9 ]
aggregator_identifier is used to assign unique aggregator identifiers
to aggregators of a bond during device enslaving.
aggregator_identifier is currently a global variable that is zeroed in
bond_3ad_initialize().
This sequence will lead to duplicate aggregator identifiers for eth1 and eth3:
create bond0
change bond0 mode to 802.3ad
enslave eth0 to bond0 //eth0 gets agg id 1
enslave eth1 to bond0 //eth1 gets agg id 2
create bond1
change bond1 mode to 802.3ad
enslave eth2 to bond1 //aggregator_identifier is reset to 0
//eth2 gets agg id 1
enslave eth3 to bond0 //eth3 gets agg id 2
Fix this by making aggregator_identifier private to the bond.
