====================
Neighbour table and ax25 cleanups
While looking at the neighbour table to what it would take to allow
using next hops in a different address family than the current packets
I found a partial resolution for my issues and I stumbled upon some
work that makes the neighbour table code easier to understand and
maintain.
Long ago in a much younger kernel ax25 found a hack to use
dev_rebuild_header to transmit it's packets instead of going through
what today is ndo_start_xmit.
When the neighbour table was rewritten into it's current form the ax25
code was such a challenge that arp_broken_ops appeard in arp.c and
neigh_compat_output appeared in neighbour.c to keep the ax25 hack alive.
With a little bit of work I was able to remove some of the hack that
is the ax25 transmit path for ip packets and to isolate what remains
into a slightly more readable piece of code in ax25_ip.c. Removing the
need for the generic code to worry about ax25 special cases.
After cleaning up the old ax25 hacks I also performed a little bit of
work on neigh_resolve_output to remove the need for a dst entry and to
ensure cached headers get a deterministic protocol value in their cached
header. This guarantees that a cached header will not be different
depending on which protocol of packet is transmitted, and it allows
packets to be transmitted that don't have a dst entry. There remains
a small amount of code that takes advantage of when packets have a dst
entry but that is something different.

Currently the iocb argument is used to idenfiy whether or not socket
lock is hold before tipc_sendmsg()/tipc_send_stream() is called. But
this usage prevents iocb argument from being dropped through sendmsg()
at socket common layer. Therefore, in the commit we introduce two new
functions called __tipc_sendmsg() and __tipc_send_stream(). When they
are invoked, it assumes that their callers have taken socket lock,
thereby avoiding the weird usage of iocb argument.

In this case, the driver won't find any configuration

Most of the time, the issues we want to debug with the
firmware dump mechanism are transient. It is then very
hard to stop the recording on time and get meaningful
data.
In order to solve this, I add here an infrastucture
of triggers. The user will supply a list of triggers
that will start / stop the recording. We have two types
of triggers: start and stop. Start triggers can start a
specific configuration. The stop triggers will be able to
kick the collection of the data with the currently running
configuration. These triggers are given to the driver by
the .ucode file - just like the configuration.
In the next patches, I'll add triggers in the code.

on the next resume (if a normal WoWLAN is used).
To solve this, skip the iteration loop when net-detect is set.

net: move skb->dropcount to skb->cb[]
Commit 977750076d ("af_packet: add interframe drop cmsg (v6)")
unionized skb->mark and skb->dropcount in order to allow recording
of the socket drop count while maintaining struct sk_buff size.
skb->dropcount was introduced since there was no available room
in skb->cb[] in packet sockets. However, its introduction led to
the inability to export skb->mark to userspace.
It was considered to alias skb->priority instead of skb->mark.
However, that would lead to the inabilty to export skb->priority
to userspace if desired. Such change may also lead to hard-to-find
issues as skb->priority is assumed to be alias free, and, as noted
by Shmulik Ladkani, is not 'naturally orthogonal' with other skb
fields.
This patch series follows the suggestions made by Eric Dumazet moving
the dropcount metric to skb->cb[], eliminating this problem
at the expense of 4 bytes less in skb->cb[] for protocol families
using it.
The patch series include compactization of bluetooth and packet
use of skb->cb[] as well as the infrastructure for placing dropcount
in skb->cb[].
