New wl12xx firmware supports scheduled scans also while connected.
Stop blocking sched scan requests when connected and add a quirk to
block in hardware that don't support it (currently wl18xx doesn't).
This requires FW version 6/7.3.10.2.112 for single-role and
6/7.5.6.0.25 for multi-role.

commit db83d136d7f753 (gianfar: Fix missing sock reference when
processing TX time stamps) added a potential sk_wmem_alloc imbalance
If the new skb has a different truesize than old one, we can get a
negative sk_wmem_alloc once new skb is orphaned at TX completion.
Now we no longer early orphan skbs in dev_hard_start_xmit(), this
probably can lead to fatal bugs.

iterator variable
If list_for_each_entry, etc complete a traversal of the list, the iterator
variable ends up pointing to an address at an offset from the list head,
and not a meaningful structure. Thus this value should not be used after
the end of the iterator. There does not seem to be a meaningful value to
provide to netdev_warn. Replace with pr_warn, since pr_err is used
elsewhere.
This problem was found using Coccinelle (http://coccinelle.lip6.fr/).

Macro spin_event_timeout() was designed for simple polling of hardware
registers with a timeout, so use it when we poll the MIIMIND register.
This allows us to return an error code instead of polling indefinitely.
Note that PHY_INIT_TIMEOUT is a count of loop iterations, so we can't use
it for spin_event_timeout(), which asks for microseconds.

The bonding debugfs support has been broken in the presence of network
namespaces since it has been added. The debugfs support does not handle
multiple bonding devices with the same name in different network
namespaces.
I haven't had any bug reports, and I'm not interested in getting any.
Disable the debugfs support when network namespaces are enabled.

It was recently reported that moving a bonding device between network
namespaces causes warnings from /proc. It turns out after the move we
were trying to add and to remove the /proc/net/bonding entries from the
wrong network namespace.
Move the bonding /proc registration code into the NETDEV_REGISTER and
NETDEV_UNREGISTER events where the proc registration and unregistration
will always happen at the right time.

as the manual of module_pci_driver says that
it can be used when the init and exit functions of
the module does nothing but the pci_register_driver
and pci_unregister_driver.
use it for rdc's r6040 driver, as the init and exit
paths does as above, and also this reduces a little
amount of code.

l4_rxhash is set on skb when rxhash is obtained from canonical 4-tuple
over transport ports/addresses.
We can set skb->l4_rxhash for all incoming TCP packets on bnx2x for
free, as cqe status contains a hash type information.

For RTL8111G, the settings of phy and firmware are replaced with
ocp functions. r8168g_mdio_{write / read} redirects the relative
settings to suitable ocp functions. A per-device variable is needed
to evaluate the real address of ocp functions.
rtl_writephy(tp, 0x1f, xxxx) is dedicated to keeping said variable
up-to-date.

For the higher mtu sizes requiring the buffer size greater than 8192,
the buffers are sent or received using multiple dma descriptors/ same
descriptor with option of multi buffer handling.
It was observed during tests that the driver was missing on data
packets during the normal ping operations if the data buffers being used
catered to jumbo frame handling.
The memory barrriers are added in between preparation of dma descriptors
in the jumbo frame handling path to ensure all instructions before
enabling the dma are complete.

It was observed that during multiple reboots nfs hangs. The status of
receive descriptors shows that all the descriptors were in control of
CPU, and none were assigned to DMA.
Also the DMA status register confirmed that the Rx buffer is
unavailable.
This patch adds the fix for the same by adding the memory barriers to
ascertain that the all instructions before enabling the Rx or Tx DMA are
completed which involves the proper setting of the ownership bit in DMA
descriptors.

Its safe to stop the BTCOEX timers 'period_timer' and
'no_stomp_timer' before disabling BTCOEX. These timers
can call ath9k_hw_btcoex_enable (or) change the BT
stomp type if they seem to be running after we had
called ath9k_hw_btcoex_disable, which is obviously
not correct.

We are doing MCI cleanup eventhough BTCOEX is not enabled
via module parameter. This means we do ath_mci_cleanup
though we skipped calling ath_mci_setup. Yet it does not
causes any issues now as we free the DMA buffer allocated
only when it is allocated during ath_mci_setup.

As soon as the interface brought up, btcoex timer starts running
eventhough the interface is in idle state and WLAN chip is moved
to full sleep mode. There is no point in running btcoex timer when
the wlan interface is in sleep mode and also it might consumes
more power on WLAN idle unassociated state. So lets stop the
btcoex when wlan is idle state.
