[SCSI] bnx2fc: NPIV ports go offline when interface is brought down & up
When there are 255 NPIV ports, and the interface is brought down & up, both
physical and NPIV ports are logged off and never logged back in. Since
discovery happens on single CPU, XID resources on that CPU will be limited,
which when exhausted the discovery fails. Increase the XID resource range to
ensure that the discovery completes successfully. Also ensure that
fc_exch_mgr_alloc() doesn't fail on the system that has lower number of CPUs.

[SCSI] bnx2fc: Handle LOGO flooding from the target
Host drops sessions when flood of unsolicited LOGOs are received from the
target. Because of unsufficient PLOGI retries, upon exceeding the retry count
of 3, the target sessions are dropped. Increased the retry count to 255 to
allow sufficient retries in this scenario.

[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.

[SCSI] bnx2fc: Fix kernel panic when deleting NPIV ports
Deleting NPIV port causes a kernel panic when the NPIV port is in the same zone
as the physical port and shares the same LUN. This happens due to the fact that
vport destroy and unsolicited ELS are scheduled to run on the same workqueue,
and vport destroy destroys the lport and the unsolicited ELS tries to access
the invalid lport. This patch fixes this issue by maintaining a list of valid
lports and verifying if the lport is valid or not before accessing it.

New 7.0 FW: bnx2x, cnic, bnx2i, bnx2fc
New FW/HSI (7.0):
- Added support to 578xx chips
- Improved HSI - much less driver's direct access to the FW internal
memory needed.
New implementation of the HSI handling layer in the bnx2x (bnx2x_sp.c):
- Introduced chip dependent objects that have chip independent interfaces
for configuration of MACs, multicast addresses, Rx mode, indirection table,
fast path queues and function initialization/cleanup.
- Objects functionality is based on the private function pointers, which
allows not only a per-chip but also PF/VF differentiation while still
preserving the same interface towards the driver.
- Objects interface is not influenced by the HSI changes which do not require
providing new parameters keeping the code outside the bnx2x_sp.c invariant
with regard to such HSI chnages.
Changes in a CNIC, bnx2fc and bnx2i modules due to the new HSI.

[SCSI] bnx2fc: common free list for cleanup commands
Cleanup commands are issued to the firmware to cleanup any stuck ios
that are supposed to be implicitly aborted. In the worst case we can
have all scsi ios filling up the free_list and we may not be able to
allocate cleanup tasks. So the driver has to reserve free_list entries
to be able to allocate the cleanup tasks. This reserve free_list common
to all cpus is allocated as one additional entry in the per cpu
free_lists.
In bnx2fc_cmd_alloc(), there is a related fix to use get_cpu() for the
free_list_index. This will prevent using the wrong index if the CPU
is preempted.
