ipv4: Cache learned PMTU information in inetpeer.
The general idea is that if we learn new PMTU information, we
bump the peer genid.
This triggers the dst_ops->check() code to validate and if
necessary propagate the new PMTU value into the metrics.
Learned PMTU information self-expires.
This means that it is not necessary to kill a cached route
entry just because the PMTU information is too old.
As a consequence:
1) When the path appears unreachable (dst_ops->link_failure
or dst_ops->negative_advice) we unwind the PMTU state if
it is out of date, instead of killing the cached route.
A redirected route will still be invalidated in these
situations.
2) rt_check_expire(), rt_worker_func(), et al. are no longer
necessary at all.

ROSE: AX25: finding routes simplification

ROSE: rose AX25 packet routing improvement
FPAC AX25 packet application is using Linux kernel ROSE
routing skills in order to connect or send packets to remote stations
knowing their ROSE address via a network of interconnected nodes.
Each FPAC node has a ROSE routing table that Linux ROSE module is
looking at each time a ROSE frame is relayed by the node or when
a connect request to a neighbor node is received.
A previous patch improved the system time response by looking at
already established routes each time the system was looking for a
route to relay a frame. If a neighbor node routing the destination
address was already connected, then the frame would be sent
through him. If not, a connection request would be issued.
The present patch extends the same routing capability to a connect
request asked by a user locally connected into an FPAC node.
Without this patch, a connect request was not well handled unless it
was directed to an immediate connected neighbor of the local node.
Implemented at a number of ROSE FPAC node stations, the present patch
improved dramatically FPAC ROSE routing time response and efficiency.

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.

from the 802.1Qaz ops without having to arbitrarily encapsulate this
data into the CEE structure.

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.

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.

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.

net: Fix lockdep regression caused by initializing netdev queues too early.
In commit
aa9421041128abb4d269ee1dc502ff65fb3b7d69 ("net: init ingress
queue") we moved the allocation and lock initialization of the queues
into alloc_netdev_mq() since register_netdevice() is way too late.
The problem is that dev->type is not setup until the setup()
callback is invoked by alloc_netdev_mq(), and the dev->type is
what determines the lockdep class to use for the locks in the
queues.
Fix this by doing the queue allocation after the setup() callback
runs.
This is safe because the setup() callback is not allowed to make any
state changes that need to be undone on error (memory allocations,
etc.). It may, however, make state changes that are undone by
free_netdev() (such as netif_napi_add(), which is done by the
ipoib driver's setup routine).
The previous code also leaked a reference to the &init_net namespace
object on RX/TX queue allocation failures.

For most of the authentication algorithms, the ICV size is 96 bits.
The AH header alignment on 32 or 64 bits gives the same results.
However for SHA-256-128 for instance, the wrong 64 bit alignment results
in adding useless padding in IPv4 AH, which is forbidden by the RFC.

mac80211: fix the skb cloned check in the tx path
Using skb_header_cloned to check if it's safe to write to the skb is not
enough - mac80211 also touches the tailroom of the skb.
Initially this check was only used to increase a counter, however this
commit changed the code to also skip skb data reallocation if no extra
head/tailroom was needed:

It added a regression at least with iwl3945, which is fixed by this patch.
