cfg80211: send regulatory beacon hint events to userspace
This informs userspace when a change has occured on a world
roaming wiphy's channel which has lifted some restrictions
due to a regulatory beacon hint.
Because this is now sent to userspace through the regulatory
multicast group we remove the debug prints we used to use as
they are no longer necessary.

On rare occasions, send BD corruptions can occur. This patch
fixes the problem by increasing the L1 entry threshold to 4
milliseconds.

tg3: Handle NVRAM absent cases
Some 57780 ASIC revision parts do not have NVRAM. Code the driver so
that it is tolerant of this configuration.

tg3: Allow screaming interrupt detection
The tg3 driver's ISR is coded to accept interrupts as its own if the
status block tag does not equal the last tag the driver has seen. The
last_tag field is updated from tg3_poll. In a screaming interrupt
situation from another device sharing tg3's IRQ, tg3_poll does not get
a chance to be called, so the last_tag will always be out of sync with
the status block tag. Consequently, the driver will continually
declare the screaming interrupts as its own, thus thwarting the
screaming interrupt detection logic.
This patch solves the problem by creating a new last_irq_tag member and
recording the status block tag in the ISR. The ISR then checks the
last_irq_tag for interrupt ownership.
Many thanks to John Marvin for the detailed bug report and analysis and
Michael Chan for the bugfix.

tg3: Fix SEEPROM accesses
The recent NVRAM patches sanitized how the driver deals with NVRAM
data, but they failed to bring the SEEPROM interfaces inline with
the new strategy. This patch brings the SEEPROM interfaces up to date.
This patch also reverts commit 0d489ffb76de0fe804cf06a9d4d11fa7342d74b9

mac80211: fix beacon loss detection after scan
Currently beacon loss detection triggers after a scan. A probe request
is sent and a message like this is printed to the log:
wlan0: beacon loss from AP 00:12:17:e7:98:de - sending probe request
But in fact there is no beacon loss, the beacons are just not received
because of the ongoing scan. Fix it by updating last_beacon after
the scan has finished.

One of the code paths sending deauth/disassoc events ends up calling
this function with rcu_read_lock held, so we must use GFP_ATOMIC in
allocation routines.

This patch fixes a hang on resume when the filesystem is not
available and request_firmware blocks.
However, the device does not accept the firmware on resume.
