bnx2x: Prevent restarting Tx during bnx2x_nic_unload
Tx queues were stopped before bp->state was changed to a value different
from BNX2X_STATE_OPEN, which allowed the bnx2x_tx_int() called from the
NAPI context to re-enable it. This then allowed the netdev->ndo_start_xmit()
to be called in the middle of the function reset and rings freeing.
This patch changes bp->state to a value different
from BNX2X_STATE_OPEN BEFORE disabling the Tx queues in order to restore the
broken protection against the above race in the bnx2x_tx_int().

Overview:
Support mapping of priorities to traffic classes and
traffic classes to transmission queues ranges in the net device.
The queue ranges are (count, offset) pairs relating to the txq
array.
This can be done via DCBX negotiation or by kernel.
As a result Enhanced Transmission Selection (ETS) and Priority Flow
Control (PFC) are supported between L2 network traffic classes.
Mapping:
This patch uses the netdev_set_num_tc, netdev_set_prio_tc_map and
netdev_set_tc_queue functions to map priorities to traffic classes
and traffic classes to transmission queue ranges.
This mapping is performed by bnx2x_setup_tc function which is
connected to the ndo_setup_tc.
This function is always called at nic load where by default it
maps all priorities to tc 0, and it may also be called by the
kernel or by the bnx2x upon DCBX negotiation to modify the mapping.
rtnl lock:
When the ndo_setup_tc is called at nic load or by kernel the rtnl
lock is already taken. However, when DCBX negotiation takes place
the lock is not taken. The work is therefore scheduled to be
handled by the sp_rtnl task.
Fastpath:
The fastpath structure of the bnx2x which was previously used
to hold the information of one tx queue and one rx queue was
redesigned to represent multiple tx queues, one for each traffic
class.
The transmission queue supplied in the skb by the kernel can no
longer be interpreted as a straightforward index into the fastpath
structure array, but it must rather be decoded to the appropriate
fastpath index and the tc within that fastpath.
Slowpath:
The bnx2x's queue object was redesigned to accommodate multiple
transmission queues. The queue object's state machine was enhanced
to allow opening multiple transmission-only connections on top of
the regular tx-rx connection.
Firmware:
This feature relies on the tx-only queue feature introduced in the
bnx2x 7.0.23 firmware and the FW likewise must have the bnx2x multi
cos support.

The following couple of patches add dcbnl an unsolicited notification of
the the DCB configuration for the CEE flavor of the DCBX protocol. This
is useful when the user-mode DCB client is not responsible for
conducting and resolving the DCBX negotiation (either because the DCBX
stack is embedded in the HW or the negotiation is handled by another
agent in the host), but still needs to get the negotiated parameters.
This functionality already exists for the IEEE flavor of the DCBX
protocol and these patches add it to the older CEE flavor.
The first patch extends the CEE attribute GET operation to include not
only the peer information, but also all the pertinent local
configuration (negotiated parameters). The second patch adds and export
a CEE specific notification routine.

net: dcbnl, add multicast group for DCB
Now that dcbnl is being used in many cases by more
than a single agent it is beneficial to be notified
when some entity either driver or user space has
changed the DCB attributes.
Today applications either end up polling the interface
or relying on a user space database to maintain the DCB
state and post events. Polling is a poor solution for
obvious reasons. And relying on a user space database
has its own downside. Namely it has created strange
boot dependencies requiring the database be populated
before any applications dependent on DCB attributes
starts or the application goes into a polling loop.
Populating the database requires negotiating link
setting with the peer and can take anywhere from less
than a second up to a few seconds depending on the switch
implementation.
Perhaps more importantly if another application or an
embedded agent sets a DCB link attribute the database
has no way of knowing other than polling the kernel.
This prevents applications from responding quickly to
changes in link events which at least in the FCoE case
and probably any other protocols expecting a lossless
link may result in IO errors.
By adding a multicast group for DCB we have clean way
to disseminate kernel DCB link attributes up to user
space. Avoiding the need for user space to maintain
a coherant database and disperse events that potentially
do not reflect the current link state.

cnic: Improve error recovery on bnx2x devices
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.

bnx2: Update driver to use new mips firmware.
bnx2-mips-06-6.2.3 and bnx2-mips-09-6.2.1.b
New firmware fixes iSCSI problems with some LeftHand targets that don't
set TTT=0xffffffff for Data-In according to spec. Firmware generates
exception warnings for this condition and becomes very slow. This is
fixed by suppressing these warnings when using default error mask.

bnx2: Add missing memory barrier in bnx2_start_xmit()
Sync DMA descriptor before hitting the TX mailbox for weak memory model

There has been discussions several years ago about this. Some believe
that writel() should guarantee ordering. Others want explicit barriers
if necessary. Today writel() does not have the ordering guarantee and
many other drivers use explicit barriers.

When RSS is enabled, interrupt vector 0 does not receive any rx traffic.
The rx producer index fields for vector 0's status block should be
