bnx2x, cnic, bnx2i, bnx2fc: Fix bnx2i and bnx2fc regressions.
commit b9871bcfd211d316adee317608dab44c58d6ea2d
bnx2x: VF RSS support - PF side
changed the configuration of the doorbell HW and it broke iSCSI and FCoE.
We fix this by making compatible changes to the doorbell address in bnx2i
and bnx2fc. For the userspace driver, we need to pass a modified CID
so that the existing userspace driver will calculate the correct doorbell
address and continue to work.

bnx2x, bnx2fc: Use per port max exchange resources
The firmware supports a maximum of 4K FCoE exchanges. In 4-port devices,
or when working in multi-function mode, this resource needs to be distributed
between the various possible FCoE functions.
This information needs to be calculated by bnx2x and propagated into bnx2fc
via cnic. bnx2fc can then use this value to calculate corresponding xid
resources instead of using global constants.

[SCSI] bnx2fc: Map the doorbell register between offload and enable requests
We used to map doorbell register after FW enable request is complete.
This causes a race condition when unsolicited event is received, and FW
sends a CQE for it. Since the doorbell is not mapped, driver does not
arm CQ, which means FW will not notify the driver for further CQ
completions. To resolve this, map the doorbell between offload and
enable, so that driver is ready to receive the unsolicited packets and
arm the CQ as soon as FW enable is performed.

[SCSI] bnx2fc: Improve error recovery by handling parity errors
During parity errors, the ramrods are not issued to FW. bnx2fc waits for the
timeout value, and proceeds with cleaning up the IOs. Since we are already
out-of-sync with FW, cleanup commands timeout too, and do not get the
completion. This operation takes 36 secs for each session to upload causing
huge delays. To fix this, bnx2fc now gets a PARITY_ERROR from cnic driver, and
upon failure, the driver does not issue any commands to the FW and finishes the
upload process sooner.

[SCSI] bnx2fc: Allocate fcoe_ctlr with bnx2fc_interface, not as a member
Currently the fcoe_ctlr associated with an interface is allocated
as a member of struct bnx2fc_interface. This causes problems when
when later patches attempt to use the new fcoe_sysfs APIs which
allow us to allocate the bnx2fc_interface as private data to a
fcoe_ctlr_device instance. The problem is that libfcoe wants to
be able use pointer math to find a fcoe_ctlr's fcoe_ctlr_device
as well as finding a fcoe_ctlr_device's assocated fcoe_ctlr. To
do this we need to allocate the fcoe_ctlr_device, with private
data for the LLD. The private data will contain the fcoe_ctlr
and its private data will be the bnx2fc_interface.
+-------------------+
| fcoe_ctlr_device |
+-------------------+
| fcoe_ctlr |
+-------------------+
| bnx2fc_interface |
+-------------------+
This prep work will allow us to go from a fcoe_ctlr_device
instance to its fcoe_ctlr as well as from a fcoe_ctlr to its
fcoe_ctlr_device once the fcoe_sysfs API is in use (later
patches in this series).

which when exhausted the discovery fails. Increase the XID resource range to

[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.

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

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: Fix MTU issue by using static MTU
bnx2x now uses seperate MTUs for networking and FCoE. FCoE MTU is fixed to 2500
and bnx2fc now needs to match this logic by using FCOE_MTU instead of
netdev->mtu.

[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.

[SCSI] bnx2fc: Broadcom FCoE offload driver
This driver is for Broadcom Netxtreme II 57712 chip. The following
patch contains the driver sources for bnx2fc driver. libfc/libfcoe
changes to enable bnx2fc have already gone through the fcoe
tree. bnx2fc is a SCSI low level driver that interfaces with SCSI
midlayer, libfc, libfcoe, cnic modules. bnx2fc driver uses services
of libfc for slow path operations such as FIP and fabric
discovery. The fast path IO perations are performed after offloading
the session information to the underlying FCoE firmware.
