This removes the custom scan cache used by orinoco.
We also have to avoid calling cfg80211_scan_done from the hard
interrupt, so we offload the entirety of scan processing to a workqueue.
This may behave strangely if you start scanning just prior to
suspending...

Initialise and register a wiphy.
Store the orinoco_private structure in the new wiphy, and use the
net_device private area to store the wireless_dev. This results in a
change to the way we navigate from a net_device to the driver private
orinoco_private, which we encapsulate in the inline function ndev_priv.
Most of the remaining calls to netdev_priv are thus replaced by
ndev_priv.
We can immediately rely on cfg80211 to handle SIOCGIWNAME, so
orinoco_ioctl_getname is removed.

accessible as IEEE80211_SKB_RXCB(skb). It also updates all
drivers to pass the rx status in there, but only by making

Commit c3a8c5b6 ("cxgb3: move away from LLTX") exposed a bug in how
cxgb3 looks up the netdev_queue it stashes away in a qset during
initialization. For multiport devices, the TX queue index it uses is
offset by the first_qset index of each port. This leads to a crash
once LLTX is removed, since hard_start_xmit is called with one TX
queue lock held, while the TX reclaim timer task grabs a different
(wrong) TX queue lock when it frees skbs.
Fix this by removing the first_qset offset used to look up the TX
queue passed into t3_sge_alloc_qset() from setup_sge_qsets().

Atheros top level menu needs a "depends WLAN_80211" to properly indent
within menuconfig and xconfig interfaces.
This is purely a visual issue but it effects all subsequent drivers.
The issue is the top level menu does not include a dependency on
WLAN_80211 so within the tree structure, Atheros is at the same level as
WLAN_80211 but when WLAN_80211 collapsed, the menu disappears along with
all subsequent drives, so it is really a subordinate.

There's a race condition -- started can be set to true
before channel is set due to the way mac80211 callbacks
currently work (->start should probably pass the channel
we would like to have initially). For now simply add a
check to hwsim to avoid dereferencing the NULL channel
pointer.

When we reclaim the tx desc, we always assume that the
last desc is a holding desc, which is not true, and skip it.
If the tx queue is drained during channel change, internal
reset and etc, the last descriptor may not be the holding
descriptor and we fail to reclaim them. This results in the
following two issues.
1. Tx stuck - We drop all the frames coming from upper layer
due to shortage in tx desc.
2. Crash - If we fail to reclaim a tx descriptor, we miss to
update the tx BA window with the seq number of the frame
associated to that desc, which, at some point, result in
the following crash due to an assert failure in ath_tx_addto_baw().
This patch fixes these two issues.

This is code extremely similar to what is committed in e1000e
already.
e1000 will no longer request 32kB slab buffers to support jumbo
frames on PCI/PCI-X adapters. This will significantly reduce the
likelyhood of order:3 allocation failures.
This new code adds support for using pages as receive buffers,
and the driver will chain multiple pages together to build a
jumbo frame for OS consumption.
The hardware takes a power of two buffer size and will
dump as much data as it can receive into 1 or more buffers.
The benefits of applying this are
1) stop akpm's dissing :-) of this lame e1000 behavior [1]
2) more efficient memory allocation (half) when using jumbo
frames, which will also allow for much better socket utilization
with jumbos since the socket is charged for the full allocation
of each receive buffer, regardless of how much is used.
3) this was a feature request by a customer
4) copybreak for small packets < 256 bytes still applies

is done with a firmware upgrade. The fixes are -
1. Ensure that the correct firmware version is used.

The call resource_size(res) returns res->end - res->start + 1 and thus the
second change is semantics-preserving. res_size is then used as the second
argument of a call to request_mem_region, and the memory allocated by this
call appears to be the same as what is released in the two calls to
release_mem_region. So the size argument for those calls should be
resource_size(size) as well. Alternatively, in the second call to
release_mem_region, the second argument could be res_size, as that variable
has already been initialized at the point of this call.
The problem was found using the following semantic patch:

It is currently possible for an asynchronous device unregister
to cause the same tun device to be unregistered twice. This
is because the unregister in tun_chr_close only checks whether
__tun_get(tfile) != NULL. This however has nothing to do with
whether the device has already been unregistered. All it tells
you is whether __tun_detach has been called.
This patch fixes this by using the most obvious thing to test
whether the device has been unregistered.
It also moves __tun_detach outside of rtnl_unlock since nothing
that it does requires that lock.

Occasionally we may see an interrupt without an event in the eq.
In intx, we currently see the event queue and return IRQ_NONE causing
a the irq to be disabled ("no one cared".) Instead, read the CEV_ISR
reg to check the existence of the interrupt.

This workaround is required for an issue in hardware where noise on the
interconnect between the MAC and PHY could be generated by a lower power
mode (K1) at 1000Mbps resulting in bad packets. Disable K1 while at 1000
Mbps but keep it enabled for 10/100Mbps and when the cable is disconnected.

Some PHYs may require two reads of the PHY_STATUS register to determine the
link status. If the PHY is being accessed by another thread it is possible
the first read could timeout and fail. In this case, put a delay in so
the second read will pick up the correct link status.
