Function Documentation

void bond_3ad_adapter_duplex_changed ( struct slave * slave )

bond_3ad_adapter_duplex_changed - handle a slave's duplex change indication : slave struct to work on

Handle reselection of aggregator (if needed) for this port.

Definition at line 2262 of file bond_3ad.c.

void bond_3ad_adapter_speed_changed ( struct slave * slave )

bond_3ad_adapter_speed_changed - handle a slave's speed change indication : slave struct to work on

Handle reselection of aggregator (if needed) for this port.

Definition at line 2234 of file bond_3ad.c.

int bond_3ad_bind_slave ( struct slave * slave )

bond_3ad_bind_slave - initialize a slave's port : slave struct to work on

Returns: 0 on success < 0 on error

Definition at line 1893 of file bond_3ad.c.

int bond_3ad_get_active_agg_info	(	struct bonding *	bond,
		struct ad_info *	ad_info
	)

bond_3ad_get_active_agg_info - get information of the active aggregator : bonding struct to work on : ad_info struct to fill with the bond's info

Returns: 0 on success < 0 on error

Definition at line 2371 of file bond_3ad.c.

void bond_3ad_handle_link_change	(	struct slave *	slave,
		char	link
	)

bond_3ad_handle_link_change - handle a slave's link status change indication : slave struct to work on : whether the link is now up or down

Handle reselection of aggregator (if needed) for this port.

Definition at line 2291 of file bond_3ad.c.

void bond_3ad_initialize	(	struct bonding *	bond,
		u16	tick_resolution
	)

bond_3ad_initialize - initialize a bond's 802.3ad parameters and structures : bonding struct to work on : tick duration (millisecond resolution)

Can be called only after the mac address of the bond is set.

		int	timeout
	)

Definition at line 1852 of file bond_3ad.c.

int bond_3ad_lacpdu_recv	(	const struct sk_buff *	skb,
		struct bonding *	bond,
		struct slave *	slave
	)

Definition at line 2463 of file bond_3ad.c.

int bond_3ad_set_carrier ( struct bonding * bond )

Definition at line 2337 of file bond_3ad.c.

void bond_3ad_state_machine_handler ( struct work_struct * work )

bond_3ad_state_machine_handler - handle state machines timeout : bonding struct to work on

The state machine handling concept in this module is to check every tick which state machine should operate any function. The execution order is round robin, so when we have an interaction between state machines, the reply of one to each other might be delayed until next tick.

This function also complete the initialization when the agg_select_timer times out, and it selects an aggregator for the ports that are yet not related to any aggregator, and selects the active aggregator for a bond.

Definition at line 2104 of file bond_3ad.c.

void bond_3ad_unbind_slave ( struct slave * slave )

bond_3ad_unbind_slave - deinitialize a slave's port : slave struct to work on

Search for the aggregator that is related to this port, remove the aggregator and assign another aggregator for other port related to it (if any), and remove the port.
