- Producer and consumer indices are also updated in the interrupt context

mmiowb() is now implied by spin_unlock() on architectures that require
it, so there is no reason to call it from driver code. This patch was
generated using coccinelle:
@mmiowb@
@@
- mmiowb();
and invoked as:
$ for d in drivers include/linux/qed sound; do \
spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done
NOTE: mmiowb() has only ever guaranteed ordering in conjunction with
spin_unlock(). However, pairing each mmiowb() removal in this patch with
the corresponding call to spin_unlock() is not at all trivial, so there
is a small chance that this change may regress any drivers incorrectly
relying on mmiowb() to order MMIO writes between CPUs using lock-free
synchronisation. If you've ended up bisecting to this commit, you can
reintroduce the mmiowb() calls using wmb() instead, which should restore
the old behaviour on all architectures other than some esoteric ia64
systems.

bnx2fc_process_new_cqes() has protection against CPU hotplug, which relies
on the per cpu thread pointer. This protection is racy because it happens
only partially with the per cpu fp_work_lock held.
If the CPU is unplugged after the lock is dropped, the wakeup code can
dereference a NULL pointer or access freed and potentially reused memory.
Restructure the code so the thread check and wakeup happens with the
fp_work_lock held.

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.

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.

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 |

This prep work will allow us to go from a fcoe_ctlr_device

fcoe_ctlr_device once the fcoe_sysfs API is in use (later
patches in this series).

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
lports and verifying if the lport is valid or not before accessing it.

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.
