ns83820: Avoid bad pointer deref in ns83820_init_one().
In drivers/net/ns83820.c::ns83820_init_one() we dynamically allocate

which is 'return netdev_priv()'. netdev_priv() takes the pointer it is

ipv6: Silence privacy extensions initialization
When a network namespace is created (via CLONE_NEWNET), the loopback
interface is automatically added to the new namespace, triggering a
printk in ipv6_add_dev() if CONFIG_IPV6_PRIVACY is set.
This is problematic for applications which use CLONE_NEWNET as
part of a sandbox, like Chromium's suid sandbox or recent versions of
vsftpd. On a busy machine, it can lead to thousands of useless

GRETH: resolve SMP issues and other problems
Fixes the following:
1. POLL should not enable IRQ when work is not completed
2. No locking between TX descriptor cleaning and XMIT descriptor handling
3. No locking between RX POLL and XMIT modifying control register
4. Since TX cleaning (called from POLL) is running in parallel with XMIT
unnecessary locking is needed.
5. IRQ handler looks at RX frame status solely, this is wrong when IRQ is
temporarily disabled (in POLL), and when IRQ is shared.
6. IRQ handler clears IRQ status, which is unnecessary
7. TX queue was stopped in preventing cause when not MAX_SKB_FRAGS+1
descriptors were available after a SKB been scheduled by XMIT. Instead
the TX queue is stopped first when not enough descriptors are available
upon entering XMIT.
It was hard to split up this patch in smaller pieces since all are tied
together somehow.
Note the RX flag used in the interrupt handler does not signal that
interrupt was asserted, but that a frame was received. Same goes for TX.
Also, IRQ is not asserted when the RX flag is set before enabling IRQ
enable until a new frame is received. So extra care must be taken to
avoid enabling IRQ and all descriptors are already used, hence dead lock
will upon us. See new POLL implementation that enableds IRQ then look at
the RX flag to determine if one or more IRQs may have been missed. TX/RX
flags are cleared before handling previously enabled descriptors, this
ensures that the RX/TX flags are valid when determining if IRQ should be
turned on again.
By moving TX cleaning from POLL to XMIT in the standard case, removes some
locking trouble. Enabling TX cleaning from poll only when not enough TX
descriptors are available is safe because the TX queue is at the same time
stopped, thus XMIT will not be called. The TX queue is woken up again when
enough descriptrs are available.
TX Frames are always enabled with IRQ, however the TX IRQ Enable flag will
not be enabled until XMIT must wait for free descriptors.
Locking RX and XMIT parts of the driver from each other is needed because
the RX/TX enable bits share the same register.

(see https://bugzilla.vyatta.com/show_bug.cgi?id=6402).
According to RCU documentation, when using hlist_nulls the reader
must handle the case of seeing a deleted entry and not proceed

Add bstats_update() helper too for classes that use
gnet_stats_basic_packed fields.
Note : Right now, TCQ_F_CAN_BYPASS shortcurt can be taken only if no
stab is setup on qdisc.

mlx4: Call alloc_etherdev to allocate RX and TX queues
Changed driver to call alloc_etherdev_mqs so that the number of TX
and RX queues can be set to correct values in the netdev device.

net: Add alloc_netdev_mqs function
Added alloc_netdev_mqs function which allows the number of transmit and
receive queues to be specified independenty. alloc_netdev_mq was
changed to a macro to call the new function. Also added
alloc_etherdev_mqs with same purpose.

cxgb4vf: fix mailbox data/control coherency domain race
For the VFs, the Mailbox Data "registers" are actually backed by
T4's "MA" interface rather than PL Registers (as is the case for
the PFs). Because these are in different coherency domains, the
write to the VF's PL-register-backed Mailbox Control can race in
front of the writes to the MA-backed VF Mailbox Data "registers".
So we need to do a read-back on at least one byte of the VF Mailbox
Data registers before doing the write to the VF Mailbox Control
register.

qlcnic: change module parameter permissions
o Updating module parameter after driver load is not supported
except auto_fw_reset parameter. Changing these parameter after
driver load, can have weird result.
o Update driver version to 5.0.15.
