Pre-allocate a skb at init time to be used for control messages to the HW
if skb allocation fails.
Tolerate failures to send messages initializing some memories at the cost of
parity error detection for these memories.
Retry sending connection id release messages if both alloc_skb(GFP_ATOMIC)
and alloc_skb(GFP_KERNEL) fail.
Do not bring the interface up if messages binding queue set to port fail to
be sent.

RX buffer rings can be comprised of non-contiguous fixed
size chunks of memory. The ring is given to the hardware
as a pointer to a location that stores the location of
the queue. If the queue is greater than 4096 bytes then
the hardware gets a list of said pointers.
This patch addes the necessary logic to generate the list if
the queue size exceeds 4096.

Addresses http://bugzilla.kernel.org/show_bug.cgi?id=13348
akpm: the reporter disappeared, so I typed it in again.
It is not possible to make clone of tagged VLAN interface to be used as
mac-based vlan interfave.
How reproducible:
Use any 802.1q tagged vlan interface, e.g. eth2.700 and clone it:
ip link add link eth2.700 address 00:04:75:cb:38:09 macvlan0 type macvlan
ip link set dev macvlan0 up
ip addr add 10.195.1.1/24 dev macvlan0
So far, so good. Now try to ping anything via macvlan0:
ping 10.195.1.2
Actual results:
For every attempted packet tx kernel writes to console:

Restore support for cards with MII-lacking PHYs as compared to removed
pre-2.6.29 eepro100 driver: use full low-level MII I/O access abstraction
by providing clean PHY-specific mdio_ctrl() functions for either standard
MII-compliant cards, slightly special ones or non-MII PHY ones.
We now have another netdev_priv member for mdio_ctrl(), thus we have some
array indirection, but we save some additional opcodes for specific
phy_82552_v handling in the common case.

This patch along with my previous patch in mac80211 "Fix the
way ADDBA count..", fixes hang in tx when connected to an HT
AP which rejects/times out on addba req.
AGGR_ADDBA_PROGRESS should be cleared in aggr state when addba
negotiation is terminated due to either addba response is timed out
or addba is denied by the AP. With out clearing this bit,
all frames are queued onto s/w queue for getting tx'd as aggr and
will never be scheduled onto hw queue.

The re-written rfkill core ensures rfkill devices are initialized to

rfkill_set_global_sw_state() (previously rfkill_set_default()) will no
longer be exported by the rewritten rfkill core.
Instead, platform drivers which can provide persistent soft-rfkill state
across power-down/reboot should indicate their initial state by calling
rfkill_set_sw_state() before registration. Otherwise, they will be
initialized to a default value during registration by a set_block call.
We remove existing calls to rfkill_set_sw_state() which happen before
registration, since these had no effect in the old model. If these
drivers do have persistent state, the calls can be put back (subject
to testing :-). This affects hp-wmi and acer-wmi.
Drivers with persistent state will affect the global state only if
rfkill-input is enabled. This is required, otherwise booting with
wireless soft-blocked and pressing the wireless-toggle key once would
have no apparent effect. This special case will be removed in future
along with rfkill-input, in favour of a more flexible userspace daemon
(see Documentation/feature-removal-schedule.txt).
Now rfkill_global_states[n].def is only used to preserve global states
over EPO, it is renamed to ".sav".

This patch introduces initial rfkill support for the ath5k driver
based on rfkill support in the cfg80211 framework.
All rfkill related code is separated into newly created rfkill.c.
Changes to existing code are minimal:
* added a new data structure ath5k_rfkill to the ath5k_softc structure
* inserted calls to HW rfkill init/deinit routines
* ath5k_intr() has been extended to handle AR5K_INT_GPIO interrupts

This patch is a back-port from aggregation testing code.
In the past, we didn't limit the amount of active tx urbs.
However, ar9170 only has a limited buffer reserved for
pending data frames.
This wasn't much of a problem with the slower 802.11b/g.
We simply stopped the full queue and moved on to something different
in the mean time. But - as you guessed it - this simple approach
stands in way for a decent aggregation implementation.

This removes the dependency on GPIO framework and lets the SPI host
driver handle the chip select. The SPI host driver is required to keep
the CS active for the entire message unless cs_change says otherwise.
This patch collects the two/three single SPI transfers into a message.
Also the delay in read path in case use_dummy_writes are not used is
moved into the SPI host driver.

Currently we support only PCIe NIC functions zero and one, and FCoE
functions as 3 and 4. Future configurations can mix these up in any
fashion.
This patch removes the 0-1 dependancy and allows usage of any of the 4
functions. We also find the alternate NIC function (if exist) and
determine our port number based on the comparison of the two functions:
Lower function number gets first port, higher function gets second port.

Phy corruption has been observed on 2-port 82571 adapters, and is root-caused
to lack of synchronization between the 2 driver instances, which conflict
when attempting to access the phy via the single MDIC register.
A semaphore exists for this purpose, and is now used on these designs. Because
PXE &/or EFI boot code (which we cannot expect to be built with this fix) may
leave the inter-instance semaphore in an invalid initial state when the driver
first loads, this fix also includes a one-time (per driver load) fix-up of the
semaphore initial state.

This driver does not indicate support for frag lists.
Furthermore, even if it did, the code is walking the frag
lists incorrectly. The idiom is:
for (iter = skb_shinfo(skb)->frag_list; iter; iter = iter->next)
but it's doing:
for (iter = skb_shinfo(skb)->frag_list; iter;
iter = skb_shinfo(iter)->frag_list)
which would never work. And this proves that this driver never
saw an SKB with active frag lists.
So just remove the code altogether and the driver TX path becomes
much simpler.
