Add a function scsi_vpd_lun_id() to return a unique device
identifcation based on the designation descriptors of
VPD page 0x83.
As devices might implement several descriptors the order
of preference is:
- NAA IEE Registered Extended
- EUI-64 based 16-byte
- EUI-64 based 12-byte
- NAA IEEE Registered
- NAA IEEE Extended
A SCSI name string descriptor is preferred to all of them
if the identification is longer than 16 bytes.
The returned unique device identification will be formatted
as a SCSI Name string to avoid clashes between different
designator types.

In the last change here, I neglected to update the cookie in one code
path: when a mgmt-tx has no real cookie sent to userspace as it doesn't
wait for a response, but is off-channel. The original code used the SKB
pointer as the cookie and always assigned the cookie to the TX SKB in
ieee80211_start_roc_work(), but my change turned this around and made
the code rely on a valid cookie being passed in.
Unfortunately, the off-channel no-wait TX path wasn't assigning one at
all, resulting in an uninitialized stack value being used. This wasn't
handed back to userspace as a cookie (since in the no-wait case there
isn't a cookie), but it was tested for non-zero to distinguish between
mgmt-tx and off-channel.
Fix this by assigning a dummy non-zero cookie unconditionally, and get
rid of a misleading comment and some dead code while at it. I'll clean
up the ACK SKB handling separately later.

Enable or disable BGX LMAC's RX/TX based on corresponding VF's
status. If otherwise, when multiple LMAC's physical link is up
then packets from all LMAC's whose corresponding VF is not yet
initialized will get forwarded to VF0. This is due to VNIC's default
configuration where CPI, RSSI e.t.c point to VF0/QSET0/RQ0.
This patch will prevent multiple copies of packets on VF0.

Intel Wired LAN Driver Updates 2015-12-01
This series contains updates to i40e and i40evf only.
Helin adds new fields to i40e_vsi to store user configured RSS config data
and the code to use it. Also renamed RSS items to clarify functionality
and scope to users. Fixed a confusing kernel message of enabling RSS size
by reporting it together with the hardware maximum RSS size.
Anjali fixes the issue of forcing writeback too often causing us to not
benefit from NAPI.
Jesse adds a prefetch for data early in the transmit path to help immensely
for pktgen and forwarding workloads. Fixed the i40e driver that was
possibly sleeping inside critical section of code.
Carolyn fixes an issue where adminq init failures always provided a message
that NVM was newer than expected, when this is not always the case for
init_adminq failures. Fixed by adding a check for that specific error
condition and a different helpful message otherwise.
Mitch fixes error message by telling the user which VF is being naughty,
rather than making them guess. Updated the queue_vector array from a
statically-sized member of the adapter structure, to a dynamically-allocated
and -sized array. This reduces the size of the adapter structure and allows
us to support any number of queue vectors in the future without changing the
code.
