The e100 driver triggers BUG_ON(buf->direction != dir)
by doing pci_map_single(..., PCI_DMA_BIDIRECTIONAL)
and pci_dma_sync_single_for_device(..., PCI_DMA_TODEVICE).
Changing the DMA direction, especially with dmabounce will result
in unexpected behaviour.

Commit 46abc02175 ("phylib: give mdio
buses a device tree presence") added a call to device_unregister() in
a situation where the caller did not intend for the device to be
freed yet, but apart from just unregistering the device from the
system, device_unregister() does an additional put_device() that is
intended to free it.
The right function to use in this situation is device_del(), which
unregisters the device from the system like device_unregister() does,
but without dropping the reference count an additional time.

This fixes a TX hang reported by Jesper Dangaard Brouer.
When an architecutre cannot provide a fully functional
64-bit atomic readq/writeq, the driver must implement
it's own. This is because only the driver can say whether
doing something like using two 32-bit reads to implement
the full 64-bit read will actually work properly.
In particular one of the issues is whether the top 32-bits
or the bottom 32-bits of the 64-bit register should be read
first. There could be side effects, and in fact that is
exactly the problem here.
The TX_CS register has counters in the upper 32-bits and
state bits in the lower 32-bits. A read clears the state
bits.
We would read the counter half before the state bit half.
That first read would clear the state bits, and then the
driver thinks that no interrupts are pending because the
interrupt indication state bits are seen clear every time.
Fix this by reading the bottom half before the upper half.

Like mac80211 did, this driver makes 'clever' use of skb->cb to pass
information along with an skb as it is requeued from the virtual device
to the physical wireless device. Unfortunately, that trick no longer
works...
Unlike mac80211, code complexity and driver apathy makes this hack
the best option we have in the short run. Hopefully someone will
eventually be motivated to code a proper fix before all the effected
hardware dies.

When the iw_cxgb3 module's cxgb3_client "add" func gets called by the
cxgb3 module, the iwarp driver ends up calling the ethtool ops get_drvinfo
function in cxgb3 to get the fw version and other info. Currently the
iwarp driver grabs the rtnl lock around this down call to serialize.
As of 2.6.27 or so, things changed such that the rtnl lock is held around
the call to the netdev driver open function. Also the cxgb3_client "add"
function doesn't get called if the device is down.
So, if you load cxgb3, then load iw_cxgb3, then ifconfig up the device,
the iw_cxgb3 add func gets called with the rtnl_lock held. If you
load cxgb3, ifconfig up the device, then load iw_cxgb3, the add func
gets called without the rtnl_lock held. The former causes the deadlock,
the latter does not.
In addition, there are iw_cxgb3 sysfs handlers that also can call
down into cxgb3 to gather the fw and hw versions. These can be called
concurrently on different processors and at any time. Thus we need to
push this serialization down in the cxgb3 driver get_drvinfo func.
The fix is to remove rtnl lock usage, and use a per-device lock in cxgb3.

The doorbell writes may be seen out of order by the firmware if they
are in WC memory since the tx spin(un)lock does not flush WC writes.
Hence if the "stop" is written on a different CPU than the "go", it
is possible that the stop will arrive after the go unless we add an
explicit memory barrier (and mmiowb() is not enough).
It fixes transmit hangs in multi tx queue mode.

Yup, this appears to be the problem, thanks. I think &hso_net->net->dev
is more intuitive for the error message, so I've used that. I've also
added missing line endings on the error messages and set our local
rfkill structure element to NULL on failure so we don't try to call
rfkill_unregister on driver removal if we failed to register at all.
The patch below Works For Me (TM); the device is detected fine, can be
removed without problems and connects ok. I'll have a prod at why the
rfkill stuff isn't working next, but I believe this cleanup of the error
handling is appropriate no matter what the issue with registration is.

ath5k_rx_status fields rs_antenna and rs_more are u8s, but we
