cfg80211: allow following country IE power for custom regdom cards
By definition WIPHY_FLAG_STRICT_REGULATORY was intended to allow the
wiphy to adjust itself to the country IE power information if the
card had no regulatory data but we had no way to tell cfg80211 that if
the card also had its own custom regulatory domain (these are typically
custom world regulatory domains) that we want to follow the country IE's
noted values for power for each channel. We add support for this and
document it.
This is not a critical fix but a performance optimization for cards
with custom regulatory domains that associate to an AP with sends
out country IEs with a higher EIRP than the one on the custom
regulatory domain. In practice the only driver affected right now
are the Atheros drivers as they are the only drivers using both
WIPHY_FLAG_STRICT_REGULATORY and WIPHY_FLAG_CUSTOM_REGULATORY --
used on cards that have an Atheros world regulatory domain. Cards
that have been programmed to follow a country specifically will not
follow the country IE power. So although not a stable fix distributions
should consider cherry picking this.

tg3: Enable EEE support for capable 10/100 devs
There are some devices in the 57765 ASIC rev that are EEE capable.
Unfortunately the EEE setup code only gets executed if the device is
gigabit capable. This patch fixes the problem.

Move limit definitions outside CONFIG_INET
They need to be available for other protocols as well, since
they are used in sock.c openly

wl12xx: alloc buffer in driver_state_read to prevent compilation warning
When compiling wl12xx for x86, there was a warning complaining about
the size of the buffer we were allocating in the stack:
drivers/net/wireless/wl12xx/debugfs.c: In function 'driver_state_read':
drivers/net/wireless/wl12xx/debugfs.c:380:1: warning: the frame size of 1040 bytes is larger than 1024 bytes
To prevent this, allocate the buffer in the heap instead.

wl12xx: call extended radio parameters for wl127x AP mode
We need to set the extended radio parameters for wl127x only.
Currently, we were only calling this command with wl127x STA mode, but
we should also do it for AP mode.
Move the call to the extended radio paramaters to the common hw_init
and use a single if for the chip type to do everything at once.

wl12xx: don't write out of bounds when hlid > WL12XX_MAX_LINKS
We should not get an hlid value bigger than WL12XX_MAX_LINKS from
wl1271_rx_handle_data(). We have a WARN_ON in case it happens. But
despite the warning, we would still go ahead and write the hlid bit
into active_hlids (a stack variable). This would cause us to
overwrite other data in the stack.
To avoid this problem, we now skip the write when issuing the warning,
so at least we don't corrupt data.

NFC: Initial LLCP support
This patch is an initial implementation for the NFC Logical Link Control
protocol. It's also known as NFC peer to peer mode.
This is a basic implementation as it lacks SDP (services Discovery
Protocol), frames aggregation support, and frame rejecion parsing.
Follow up patches will implement those missing features.
This code has been tested against a Nexus S phone implementing LLCP 1.0.

NFC: Set and get DEP general bytes
Without an API for setting and getting the local and remote general bytes,
drivers won't be able to properly establish a DEP link.
This API also allows them to propagate the remote general bytes they get
from the DEP link establishment up to the LLCP layer.
