This change is meant to address several race issues that become possible
because next_to_watch could possibly be set to a value that shows that the
descriptor is done when it is not.  In order to correct that we instead make
next_to_watch a pointer that is set to NULL during cleanup, and set to the
eop_desc after the descriptor rings have been written.

To enforce proper ordering the next_to_watch pointer is not set until after
a wmb writing the values to the last descriptor in a transmit.  In order to
guarantee that the descriptor is not read until after the eop_desc we use the
read_barrier_depends which is only really necessary on the alpha architecture.

====================
For the 57766 devices with no NVRAM, there is not enough space for the complete
boot code with EEE support. On these devices, the tg3 driver has to download
a service patch firmware to the scratchpad for the boot code to execute. This
patchset adds support to do the above.

A major portion of this patchset is refactoring the existing firmware download
section to allow a cleaner merge of the 57766 download. The 57766 firmware
differs from previous firmware in that it's not written to a contiguous area in
memory. It consists of multiple fragments to be written to different locations.
The patchset makes an attempt to make the new firmware format to be an
extension of the existing format.

The current firmware header parsing is complicated due to interpreting it as a
u32 array and accessing header members via array offsets. Add tg3_firmware_hdr
structure to access the firmware fields instead of hardcoding offsets. The same
header format will be used for individual firmware fragments in the 57766.

The fw_hdr and tg3 structures have all the information required for
loading the fw. Remove the redundant fw_info structure and pass fw_hdr
instead.

The 57766 rxcpu needs to be paused/resumed when we download the firmware just
like we do for existing firmware. Refactor the pause/resume code to be
reusable.

This patch also renames the "offset" argument of tg3_halt_cpu to "cpu_base"
since that's what it really is.

tg3 used the fw_needed member loosely as a synonym for firmware TSO. Now
that the 57766 needs firmware download support, fw_needed can no longer be
used like this. This patch creates a new FW_TSO flag and changes the
code to use it.

Also rearrange all the TSO flags together in the enum.

====================
This is a short series that now allows mac filter programming on any
card that support IFF_UNICAST_FLT by using the existing FDB interface.

Some existing drivers that had FDB functionality usually supported
it only in SR-IOV mode.  Since that's not always enabled, and
we want to take advantage of IFF_UNICAST_FLT support, these drivers
have been converted to call the default handler when not in SRIOV mode.
====================

Allow qlcnic to use the generic fdb handler when the driver options
are not enabled.   Untill the driver is fully fixed, this allows
the use of the FDB interface with qlogic driver, but simply puts
the driver into promisc mode since the driver currently does not
support IFF_UNICAST_FLT.

For fdb_add, use the default handler in the non-SRIOV case.
For the other fdb handlers, just remove them and use the
default ones.

If the driver does not support the ndo_op use the generic
handler for it. This should work in the majority of cases.
Eventually the fdb_dflt_add call gets translated into a
__dev_set_rx_mode() call which should handle hardware
support for filtering via the IFF_UNICAST_FLT flag.

Namely IFF_UNICAST_FLT indicates if the hardware can do
unicast address filtering. If no support is available
the device is put into promisc mode.
