AR9003 seems to have issues sometimes with fast channel change
in 5GHz and this case is handled specifically for AR9280 by doing
a full reset. Let's do a full reset for 5GHz channles of AR9380
& for all channels of AR9280 pci chips.

This patch reverts commit 9b7688328422b88a7a15dc0dc123ad9ab1a6e22d which
was introduced in 2.6.38-rc1. It works around a problem where the iwlagn
driver stimulates a bug crashing (requiring power cycle to recover) some
APs under heavy traffic.

mac80211: fix suspend/resume races with unregister hw
Above commit add rtnl_lock() into wiphy_register(), what cause deadlock
when initializing ipw2x00 driver, which itself call wiphy_register()
from register_netdev() internal callback with rtnl mutex taken.
To fix move wiphy_register() outside register_netdev(). This solution
have side effect of not creating /sys/class/net/wlanX/phy80211 link,
but that's a minor issue we can live with.

Fix a number of issues in ibmveth_set_csum_offload:
- set_attr6 and clr_attr6 may be used uninitialised
- We store the result of the IPV4 checksum change in ret but overwrite
it in a couple of places before checking it again later. Add ret4
to make it obvious what we are doing.
- We weren't clearing the NETIF_F_IP_CSUM and NETIF_F_IPV6_CSUM flags
if the enable of that hypervisor feature failed.

descs[].fields.address is 32bit which truncates any dma mapping
errors so dma_mapping_error() fails to catch it.

The new firmware format includes capability bits which make it

Currently the load address was calculated everytime when it was needed,
and with a mess if clauses. Simplify this by adding a field to struct
ath6kl for each address and choose the address with simple switch
statements.
Also move the code just after target version is retrieved. That way it's
easier to override the values later in the boot process.

Brent reported that ath6kl busy loops if firmware doesn't boot for some
reason (in this case he was using an older firmware which wasn't supported
by ath6kl).
Investigation revealed that this was even on purpose,
ath6kl_bmi_get_rx_lkahd() had a parameter to disable the timeout check,
which is extremely evil. I didn't find any reason why the timeout needs
to be disabled so I just removed the feature. The function already busyloops
a maximum of one second if it doesn't get an answer, even that's too long.
If something takes longer than that a more friendly approach is needed.

It was possible to inadvertently add additional interrupt causes to the
MSI-X other interrupt. This occurred when things such as RX buffer overrun
events were being triggered at the same time as an event such as a Flow
Director table reinit request. In order to avoid this we should be
explicitly programming only the interrupts that we want enabled. In
addition I am renaming the ixgbe_msix_lsc function and interrupt to drop
any implied meaning of this being a link status only interrupt.
Unfortunately the patch is a bit ugly due to the fact that ixgbe_irq_enable
needed to be moved up before ixgbe_msix_other in order to have things
defined in the correct order.

This patch is a minor whitespace cleanup to compress the device ID

This change consolidates all of the MSI-X interrupt and polling routines
into two single functions. One for the interrupt and one for the code.
The main advantage to doing this is that the compiler can optimize the
routines into single monolithic functions which should allow all of them
function to occupy a single block of memory and as such avoid jumping
around.

This change makes it so that the default Tx work limit is 256 buffers or
1/2 of an entire ring instead of a full ring size so that it is much more
likely that we will be able to actually reach the work limit value.
Previously with the value set to an entire ring it would not have been
possible for us to trigger an event due to the fact that the Tx work is
stopped at the point where we cannot place one more buffer on the ring and
it is not restarted until cleanup is complete.

This patch does several things:
- introduces __ethtool_get_settings which is called from ethtool code and
from drivers as well. Put ASSERT_RTNL there.
- dev_ethtool_get_settings() is replaced by __ethtool_get_settings()
- changes calling in drivers so rtnl locking is respected. In
iboe_get_rate was previously ->get_settings() called unlocked. This
fixes it. Also prb_calc_retire_blk_tmo() in af_packet.c had the same
problem. Also fixed by calling __dev_get_by_index() instead of
dev_get_by_index() and holding rtnl_lock for both calls.
- introduces rtnl_lock in bnx2fc_vport_create() and fcoe_vport_create()
so bnx2fc_if_create() and fcoe_if_create() are called locked as they
are from other places.
- use __ethtool_get_settings() in bonding code
