dd68153def atl1: Do not use legacy PCI power management
The atl1 driver uses the legacy PCI power management, so it has to
do some PCI-specific things in its ->suspend() and ->resume()
callbacks, which isn't necessary and should better be done by the PCI
subsystem-level power management code.

Convert atl1 to the new PCI power management framework and make it
let the PCI subsystem take care of all the PCI-specific aspects of
device handling during system power transitions.

55320cb58b ixgbe: DCB, abstract out dcb_config from DCB hardware configuration
Currently the routines that configure the HW for DCB require a
ixgbe_dcb_config structure. This structure was designed to support
the CEE standard and does not match the IEEE standard well.

This patch changes the HW routines in ixgbe_dcb_8259x.{ch} to use
raw pfc and bandwidth values. This requires some parsing of the DCB
configuration but makes the HW routines independent of the data
structure that contains the DCB configuration.

The primary advantage to doing this is we can do HW setup directly
from the 802.1Qaz ops without having to arbitrarily encapsulate this
data into the CEE structure.

53bb9f80b3 ixgbe: DCB, only reprogram HW if the FCoE priority is changed
If the FCoE priority is not changing do not set the RESET and
APP_UPCHG bits. This causes unneeded HW resets and which can
cause unneeded LLDP frames and negotiations.

The current check is not sufficient because the FCoE priority
can change twice during a negotiation which results in the
bits being set. This occurs when the switch changes the
priority or when the link is reset with switches that do not
include the APP priority until after PFC has been negotiated.

This results in set_app being called with the local APP
priority. Then the negotiation completes and set_app
is called again with the peer APP priority. The check
fails so the device is reset and the above occurs again
resulting in an endless loop of resets.

By only resetting the device if the APP priority has really
changed we short circuit the loop.

c2f7f0e7b3 batman-adv: Use successive sequence numbers for fragments
The two fragments of an unicast packet must have successive sequence numbers to
allow the receiver side to detect matching fragments and merge them again. The
current implementation doesn't provide that property because a sequence of two
atomic_inc_return may be interleaved with another sequence which also changes
the variable.

The access to the fragment sequence number pool has either to be protected by
correct locking or it has to reserve two sequence numbers in a single fetch.
The latter one can easily be done by increasing the value of the last used
sequence number by 2 in a single step. The generated window of two currently
unused sequence numbers can now be scattered across the two fragments.

6431cbc25f inet: Create a mechanism for upward inetpeer propagation into routes.
If we didn't have a routing cache, we would not be able to properly
propagate certain kinds of dynamic path attributes, for example
PMTU information and redirects.

The reason is that if we didn't have a routing cache, then there would
be no way to lookup all of the active cached routes hanging off of
sockets, tunnels, IPSEC bundles, etc.

Consider the case where we created a cached route, but no inetpeer
entry existed and also we were not asked to pre-COW the route metrics
and therefore did not force the creation a new inetpeer entry.

If we later get a PMTU message, or a redirect, and store this
information in a new inetpeer entry, there is no way to teach that
cached route about the newly existing inetpeer entry.

The facilities implemented here handle this problem.

First we create a generation ID.  When we create a cached route of any
kind, we remember the generation ID at the time of attachment.  Any
time we force-create an inetpeer entry in response to new path
information, we bump that generation ID.

The dst_ops->check() callback is where the knowledge of this event
is propagated.  If the global generation ID does not equal the one
stored in the cached route, and the cached route has not attached
to an inetpeer yet, we look it up and attach if one is found.  Now
that we've updated the cached route's information, we update the
route's generation ID too.

This clears the way for implementing PMTU and redirects directly in
the inetpeer cache.  There is absolutely no need to consult cached
route information in order to maintain this information.

At this point nothing bumps the inetpeer genids, that comes in the
later changes which handle PMTUs and redirects using inetpeers.

ddd4aa424b inetpeer: Add redirect and PMTU discovery cached info.
Validity of the cached PMTU information is indicated by it's
expiration value being non-zero, just as per dst->expires.

The scheme we will use is that we will remember the pre-ICMP value
held in the metrics or route entry, and then at expiration time
we will restore that value.

In this way PMTU expiration does not kill off the cached route as is
done currently.

Redirect information is permanent, or at least until another redirect
is received.
