This masks the PHY TX error interrupt, if debugging is disabled.
Currently we have a bug somewhere which triggers this interrupt once
in a while. (Depends on the network noise/quality). While this is nonfatal,
it scares the hell out of users and we frequently receive bugreports
that incorrectly identify this error message as the reason.
There's another problem with this. The PHY TX error interrupt is protected
with a watchdog that will restart the device if it keeps triggering very often.
This is used to fix interrupt storms from completely broken devices.
However, this watchdog might trigger in completely normal operation.
If the TX capacity of the card is saturated, the likeliness of the watchdog
triggering increases, as more TX errors occur. The current threshold
for the watchdog is 1000 errors in 15 seconds.
This patch adds a workaround for the issue by just enabling the interrupt
if debugging is disabled (by Kconfig or by modparam).
This has the downside that real fatal PHY TX errors are not caught anymore.
But this is nonfatal due to the following reasons:
* If the card is not able to transmit anymore, MLME will notice anyway.
* I did _never_ see a real fatal PHY TX error in a mainline b43 driver.
* It does _not_ result in interrupt storms or something like that.
It will simply result in a stalled card. It can be debugged by enabling
the debugging module parameter.

The current macro is wrong, because detects some AR5416 devices as an
AR9100 device. The AR5416 devices would have performance issues after
this change, because the contents of the ar5416 specific and of the
ar9100 specificinitval arrays are swapped. Fortunately we can correct
this with the rename of the arrays simply.

debugfs ath9k/phy#/wiphy can be used to show the current list of
virtual wiphys and to add/remove virtual wiphys. Eventually, this
interface could be replaced with a cfg80211/nl80211 command that is
passed through mac80211.
For example:
# cat /debug/ath9k/phy0/wiphy
primary: phy0
# echo add > /debug/ath9k/phy0/wiphy
# cat /debug/ath9k/phy0/wiphy
primary: phy0
secondary: phy1
# echo del=phy1 > /debug/ath9k/phy0/wiphy
# cat /debug/ath9k/phy0/wiphy
primary: phy0
In addition, following commands can be used to test pausing and
unpausing of the virtual wiphys:
pause=phy1
unpause=phy1
select=phy1
(select pauses and unpauses wiphys automatically based on channel)
schedule=500
(set wiphy scheduling interval in msec; 0 = disable; default value: 500)

This is the initial step in allowing ath9k to register multiple
virtual radios (wiphys). The goal of virtual radios is to allow the
same radio to be shared for multiple virtual interfaces that may
operate on different channels. The mac80211 virtual interface support
is designed only for single channel operation and as such, it is not
suitable for this type of use. Anyway, it can be used on top of the
virtual radio concept, if desired (e.g., use two virtual radios to
handle two channels and then add multiple mac80211 virtual interfaces
on top of each virtual radio).
The new struct ath_wiphy is now registered as the driver data
structure for wiphy. This structure has a pointer to the shared (among
virtual wiphys of the same physical radio) struct ath_softc data. The
primary wiphy maintains the allocated memory for ath_softc. Secondary
(virtual) wiphys will only allocate the new ath_wiphy structure.
Registration of secondary wiphys is added in a separate patch.

By exporting the register base, and word size to userspace
through debugfs it will be easier to create scripts which
parse the register information. This makes debugging and
register dumps information easier.
This will break my previous scripts which dumped and parsed
all information, but since this is only for debugging purposes
this change should not be a problem.
Dumpfiles created with the old version can be easily manually
edited to make them compatible with this new approach, which
means there will be no problems comparing dumps from the
different versions either.
Also be more consistent with using tabs to seperate different
