It does seem odd though to have a DBG_EMERG and not always
emit it.
What might also be useful for any embedded use is to add
CONFIG_RTLWIFI_DEBUG to conditionally remove all of the
debug logging code to reduce the largish object size.
This reduces the object size by about 1/3 (250KB)
when CONFIG_RTLWIFI_DEBUG is not set.

When deauth is requested while an auth or assoc
work item is in progress, we currently delete it
without regard for any state it might need to
clean up. Fix it by cleaning up for those items.
In the case Pontus found, the problem manifested
itself as such:
authenticate with 00:23:69:aa:dd:7b (try 1)
authenticated
failed to insert Dummy STA entry for the AP (error -17)
deauthenticating from 00:23:69:aa:dd:7b by local choice (reason=2)
It could also happen differently if the driver
uses the tx_sync callback.
We can't just call the ->done() method of the work
items because that will lock up due to the locking
in cfg80211. This fix isn't very clean, but that
seems acceptable since I have patches pending to
remove this code completely.

Use local->tx_headroom instad of local->hw.extra_tx_headroom.
local->tx_headroom is the max of hw.extra_tx_headroom required by the
driver and the headroom required by mac80211 for status reporting. On
drivers where hw.extra_tx_headroom is smaller than what mac80211
requires (e.g. ath5k), we would not reserve sufficient buffer space to
report tx status.
Also, don't reserve local->tx_headroom + local->hw.extra_tx_headroom.

John Linville had to revert the part of USB support which was already
in ath6kl due to build problems in commit cb00ec382b ("ath6kl: revert
USB support"). Now that I fixed the build problems properly by adding
ath6kl_core.ko kernel module it's possible to add back the
(incomplete) USB support. This patch is a revert of John's patch and
adds back the USB code which as already in ath6kl, only difference
being minor changes in Makefile and adapting usb.c to new core
function names.
Note that USB support in ath6kl is not complete yet. This code only
makes it possible to boot firmware but as HTC layer does not yet
support USB it's not possible to send any WMI commands nor data
packets to the firmware. That will be added soon.

We don't need it as debug calls already have a log level and compiler
should be smart enough to optimise away the code when ath6kl debug code

Kdump kernels leave MSI-X interrupts (as setup by the crashed kernel)
enabled. However, kdump only enables one CPU in the new environment,
thus causing tg3 to abort MSI-X setup. When the driver attempts to
enable INTA or MSI interrupt modes on a kdump kernel, interrupt
delivery fails.
This patch attempts to workaround the problem by forcing the driver
to enable a single MSI-X interrupt. In such a configuration, the
device's multivector interrupt mode must be disabled.
