Take care of FW & NVS with the auto-detection between wl127x and
wl128x.
[Moved some common code outside if statements and added notes about
NVS structure assumptions; Fixed a bug when checking the nvs size: if
the size was incorrect, the local nvs variable was set to NULL, it
should be wl->nvs instead. -- Luca]
[Merged with potential buffer overflow fix -- Luca]

Definitions to support wl128x:
- New FW file name
- Chip ID
- New PLL Configuration Algorithm macros that will be used at wl128x
boot stage
- Rename NVS macro name: wl127x and wl128x are using the same NVS
file name. However, the ini parameters between them are
different. The driver will validate the correct NVS size in
wl1271_boot_upload_nvs().

We are currently using this flag to check whether it's safe
to call into ->request_fn(). If it is set, we punt to kblockd.
But we get a lot of false positives and excessive punts to
kblockd, which hurts performance.
The only real abuser of this infrastructure is SCSI. So export
the async queue run and convert SCSI over to use that. There's
room for improvement in that SCSI need not always use the async
call, but this fixes our performance issue and they can fix that
up in due time.

- the MSS value is actually contained in a 11 bits wide (0x7ff) field.
The extra bit in the former MSSMask did encompass the TSO command
bit ("LargeSend") as well (0xfff). Oops.
- the Tx descriptor layout is not the same through the whole chipset
family. The 8169 documentation, the 8168c documentation and Realtek's
drivers (8.020.00, 1.019.00, 6.014.00) highlight two layouts:
1. 8169, 8168 up to 8168b (included) and 8101
2. {8102e, 8168c} and beyond
- notwithstanding the "first descriptor" and "last descriptor" bits, the
same Tx descriptor content is enforced when a packet consists of several
descriptors. The chipsets are documented to require it.

Mouse gets "stuck" after restore of PV guest but buttons are in working
condition.
If driver has been configured for ABS coordinates at start it will get
XENKBD_TYPE_POS events and then suddenly after restore it'll start getting
XENKBD_TYPE_MOTION events, that will be dropped later and they won't get
into user-space.
Regression was introduced by hunk 5 and 6 of
5ea5254aa0
("Input: xen-kbdfront - advertise either absolute or relative
coordinates").
Driver on restore should ask xen for request-abs-pointer again if it is
available. So restore parts that did it before 5ea5254.

When testing some new P2P code, Angie found that the

up being bigger than a regular command. This is quite
obvious -- a normal command is limited to roughly 360
bytes but a beacon may be much larger of course.
To fix this, use the huge command buffer.

Since huge commands all share a single buffer,
there can only be a single one in flight at a

other. This is true in the driver now, but it
seems like a possible source of bugs, so add

sent synchronously.
