This patch enables ethtool to correctly identify flow control (pause
frame) auto negotiation, as well as disallow enabling it when it is not
supported. The ixgbe_device_supports_autoneg_fc function is exported and
used for this purpose.
There is also one minor cleanup of the device_supports_autoneg_fc by
removing an unnecessary return statement.

This patch removes the queuing that was previously done for L4 packets
as it is not needed. The filter does not provide functionality, and it
is possible that queue setup here could trample settings done else-where
in the driver. (for example it may use a queue which isn't setup.)
Setting of the queue is not required for hardware timestamping and could
have inadverdent side effects.

This patch removes a magic number that was used for the ETQF used for

Move encoder's dpms updating into exynos_drm_encoder_commit
function because when crtc's dpms is updated, encoder's dpms
is updated also. This would induce the issue that encoder
isn't disabled after crtc is disabled.
Changelog v1:
This patch fixes a issue that overlay data aren't applied
to real hardware when dpms off goes to on after setcrtc
was requested like below,
dpms off -> setcrtc -> dpms off -> dpms on
For this, it makes encoder's dpms to be updated when

When a write to a replacement device completes, we carefully
and correctly found the rdev that the write actually went to
and the blithely called rdev_dec_pending on the primary rdev,
even if this write was to the replacement.
This means that any writes to an array while a replacement
was ongoing would cause the nr_pending count for the primary
device to go negative, so it could never be removed.
This bug has been present since replacement was introduced in
3.3, so it is suitable for any -stable kernel since then.

When a replacement operation completes there is a small window
when the original device is marked 'faulty' and the replacement
still looks like a replacement. The faulty should be removed and
the replacement moved in place very quickly, bit it isn't instant.
So the code write out to the array must handle the possibility that
the only working device for some slot in the replacement - but it
doesn't. If the primary device is faulty it just gives up. This
can lead to corruption.
So make the code more robust: if either the primary or the
replacement is present and working, write to them. Only when
neither are present do we give up.
This bug has been present since replacement was introduced in
3.3, so it is suitable for any -stable kernel since then.

The ixp4xx queue manager uses "const struct qmgr_regs __iomem *" as the
type for a pointer that is passed to __raw_writel, which is not
allowed because of the const-ness.
Dropping the 'const' keyword fixes the problem. While we're here,
let's also drop the useless type cast.
Without this patch, building ixp4xx_defconfig results in:
