[SCSI] bnx2fc: Introduce interface structure for each vlan interface
Currently, bnx2fc has a hba structure that can work with only a single vlan
interface. When there is a change in vlan id, it does not have the capability
to switch to different vlan interface. To solve this problem, a new structure
called 'interface' has been introduced, and each hba can now have multiple
interfaces, one per vlan id.
Most of the patch is a moving the interface specific fields from hba to the
interface structure, and appropriately modifying the dereferences. A list of
interfaces (if_list) is maintained along with adapter list. During a create
call, the interface structure is allocated and added to if_list and deleted &
freed on a destroy call. Link events are propagated to all interfaces
belonging to the hba.
