This fixes Bug #9414
Since addition of the rfkill callback, the LED associated with the off
switch on the radio has not worked for several reasons:
(1) Essential data in the rfkill structure were missing.
(2) The rfkill structure was initialized after the LED initialization.
(3) There was a minor memory leak if the radio LED structure was inited.
Once the above problems were fixed, additional difficulties were noted:
(4) The radio LED was in the wrong state at startup.
(5) The radio switch had to be manipulated twice for each state change.
(6) A circular mutex locking situation existed.
(7) If rfkill-input is built as a module, it is not automatically loaded.
This patch fixes all of the above.

With some PHYs, when the link goes away, the EMAC reset fails due
to the loss of the RX clock I believe.
The old EMAC driver worked around that using some internal chip-specific
clock force bits that are different on various 44x implementations.
This is an attempt at doing it differently, by avoiding the reset when
there is no link, but forcing loopback mode instead. It seems to work
on my Taishan 440GX based board so far.

Add new hash for balance-xor and 802.3ad modes. Originally
submitted by "Glenn Griffin" <ggriffin.kernel@gmail.com>; modified by
Jay Vosburgh to move setting of hash policy out of line, tweak the
documentation update and add version update to 3.2.2.
Glenn's original comment follows:
Included is a patch for a new xmit_hash_policy for the bonding driver
that selects slaves based on MAC and IP information. This is a middle
ground between what currently exists in the layer2 only policy and the
layer3+4 policy. This policy strives to be fully 802.3ad compliant by
transmitting every packet of any particular flow over the same link.
As documented the layer3+4 policy is not fully compliant for extreme
cases such as ip fragmentation, so this policy is a nice compromise
for environments that require full compliance but desire more than the
layer2 only policy.

Also remove trailing spaces from multivalued files.

0000000 e t h - l e f t e t h - r i g
0000020 h t \n \0
0000025
It mostly entails deleting '+1'-s after sprintf() calls: the return value
of sprintf is the number of characters printed, without the closing NUL,
ie. exactly what the sysfs interface requires. The three multivalue
cases are different, because they also have to swallow back a trailing
space.
