On embedded hardware it's normal to not have a PCI device for the PCI
bridge that the wifi card is attached to. pdev->bus->self will be
NULL in that case. In that case, simply return without emitting an
useless kernel stack trace.

While switching b/w HT20/40, the current channel's nf values
are updated into history buffer. Since the current channel's
channel type, channel flag got updated before reading
nf value from hw. This channel type mismatch is causing invalid
readings when hw is on ht20 but getnf tries to read on extn chains.

Before doing hw reset the current channel's noisefloor readings
are updated into history buffer. The extension chain's readings
are considered only if the current channel was configured in HT40.
While moving from HT40 to HT20, the extn chain's readings are
skipped though the current channel is in ht40. This patch updates
extn chain reading based on channel flag.

Whenever RXEOL is received, both RXORN and RXEOL got cleared
to avoid rx overrun interrupt storm. This was handled only for
edma chips. The same scenario was also observered with AR9280,
doing frequent channel type switch b/w HT20/40 with bidi traffic
that is causing failure to stop rx dma. This patch clears
the RXEOL & RXORN interrupts for all chips.

The WAR which adds extra delimiters when using RTS/CTS
with aggregation and non-enterprise AR9003 chips.
This extra padding is done after doing all the 4ms limit
checks and hence the total aggregate sizes are exceeding
the allowed duration. This patch limits the aggregate
sizes appropriately after including these extra delimiters.

In this implementation, a mesh gate is a root node with a certain bit
set in its RANN flags. The mpath to this root node is marked as a path
to a gate, and added to our list of known gates for this if_mesh. Once a
path discovery process fails, we forward the unresolved frames to a
known gate. Thanks to Luis Rodriguez for refactoring and bug fix help.

If is_main_vif(ar, vif) reports that we have to fall back
to software encryption, we goto err_softw; before locking ar->mutex.
As a result, we have unprotected call to carl9170_set_operating_mode
and unmatched mutex_unlock.
The patch fix the issue by adding mutex_lock before goto.

The tracing code used sched_clock() to get tracing timestamps, which
ends up calling xen_clocksource_read(). xen_clocksource_read() must
disable preemption, but if preemption tracing is enabled, this results
in infinite recursion.
I've only noticed this when boot-time tracing tests are enabled, but it
seems like a generic bug. It looks like it would also affect
kvm_clocksource_read().
