So far, only net_device * could be passed along with netdevice notifier

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.

In INTA mode, cnic and bnx2x share the same IRQ. During chip reset,
for example, cnic will stop servicing IRQs after it has shutdown the
cnic hardware resources. However, the shared IRQ is still active as
bnx2x needs to finish the reset. There is a window when bnx2x does
not know that cnic is no longer handling IRQ and things don't always
work properly.
Add a flag to tell bnx2x that cnic is handling IRQ. The flag is set
before the first cnic IRQ is expected and cleared when no more cnic
IRQs are expected, so there should be no race conditions.

If the initiator and target try to close the connection at about the same
time, there is a race condition in the termination sequence for bnx2x.
Fix the problem by waiting for the remote termination to complete before
deleting the Connection ID. This will prevent the firmware assert.

This patch moves the bnx2x and cnic drivers into using FW 7.8.2
which was recently submitted into the linux-firmware tree.
A short summary of minor bugs fixed by this FW:
1. In switch dependent mode, fix several issues regarding inner vlan
vs. DCB priorities.
2. iSCSI - not all packets were completed on a forward channel.
3. DCB - fixed for 4-port devices.
4. Fixed false parity reported in CAM memories when operating near -5%
on the 1.0V core supply.
5. ETS default settings are set to fairness between traffic classes
(rather than strict priority), and uses the same chip receive buffer
configuration for both PFC and pause.
For a complete list of fixes made by this FW, see commit 236367db
in the linux-firmware git repository.

iterator variable
If list_for_each_entry, etc complete a traversal of the list, the iterator
variable ends up pointing to an address at an offset from the list head,
and not a meaningful structure. Thus this value should not be used after
the end of the iterator. There does not seem to be a meaningful value to
provide to netdev_warn. Replace with pr_warn, since pr_err is used
elsewhere.
This problem was found using Coccinelle (http://coccinelle.lip6.fr/).

We register with bnx2x before we allocate ctx_tbl structure, so it is
possible for bnx2x to call cnic_ctl before the structure is allocated.
This can sometimes cause NULL pointer dereference of cp->ctx_tbl. We
fix this by adding simple checking for valid state before proceeding.
The cnic_ctl call is RCU protected so we don't have to deal with race
conditions.
Because of the additional checking, we need to finish the shutdown
before clearing the CNIC_UP flag.

Adding casts of objects to the same type is unnecessary
and confusing for a human reader.
For example, this cast:
int y;
int *p = (int *)&y;
I used the coccinelle script below to find and remove these
unnecessary casts. I manually removed the conversions this
script produces of casts with __force, __iomem and __user.
@@
type T;
T *p;
@@
- (T *)p

When a bnx2x device encounters parity errors, it will not respond to all
SPQ messages. As a result, the shutdown sequence before reset can take
a long time as the ulp drivers (bnx2i/bnx2fc) have to wait for timeout
of all such messages.
To improve this scenario, when bnx2x returns error on the SPQ, we'll send
an immediate response to the ulp drivers to avoid such lengthy timeouts.
Adjust the return code of relevant functions to return error only if
the message cannot be sent on the SPQ so that we'll generate an error
completion to the ulp drivers.
