void bond_change_active_slave	(	struct bonding *	bond,
		struct slave *	new_active
	)

change_active_interface - change the active slave into the specified one : our bonding struct : the new slave to make the active one

Set the new slave to the bond's settings and unset them on the old curr_active_slave. Setting include flags, mc-list, promiscuity, allmulti, etc.

If 's link state is BOND_LINK_BACK we'll set it to BOND_LINK_UP, because it is apparently the best available slave we have, even though its updelay hasn't timed out yet.

If new_active is not NULL, caller must hold bond->lock for read and curr_slave_lock for write_bh.

Returns NULL if list is empty, bond->next_vlan if is NULL, or ->next otherwise (even if it is itself again).

This functions should be called when one of the following occurs:

The old curr_active_slave has been released or lost its link.
The primary_slave has got its link back.
A slave has got its link back and there's no old curr_active_slave.
