pch_gbe: run the ptp bpf just once per packet

register_sysctl_rotable never caught on as an interesting way to
register sysctls. My take on the situation is that what we want are
sysctls that we can only see in the initial network namespace. What we
have implemented with register_sysctl_rotable are sysctls that we can
see in all of the network namespaces and can only change in the initial
network namespace.
That is a very silly way to go. Just register the network sysctls
in the initial network namespace and we don't have any weird special
cases to deal with.
The sysctls affected are:
/proc/sys/net/ipv4/ipfrag_secret_interval
/proc/sys/net/ipv4/ipfrag_max_dist
/proc/sys/net/ipv6/ip6frag_secret_interval
/proc/sys/net/ipv6/mld_max_msf
I really don't expect anyone will miss them if they can't read them in a
child user namespace.

Right now all of the networking sysctl registrations are running in a
compatibiity mode. The natvie sysctl registration api takes a cstring
for a path and a simple ctl_table. Implement register_net_sysctl so
that we can register network sysctls without needing to use
compatiblity code in the sysctl core.
Switching from a ctl_path to a cstring results in less boiler plate
and denser code that is a little easier to read.
I would simply have changed the arguments to register_net_sysctl_table
instead of keeping two functions in parallel but gcc will allow a
ctl_path pointer to be passed to a char * pointer with only issuing a
warning resulting in completely incorrect code can be built. Since I
have to change the function name I am taking advantage of the situation
to let both register_net_sysctl and register_net_sysctl_table live for a
short time in parallel which makes clean conversion patches a bit easier
to read and write.

bonding: start slaves with link down for ARP monitor
Initialize slave device link state as down if ARP monitor is
active and net_carrier_ok() returns zero. Also shift initial
value of its last_arp_tx so that it doesn't immediately cause
fake detection of "up" state.
When ARP monitoring is used, initializing the slave device with
up link state can cause ARP monitor to detect link failure
before the device is really up (with igb driver, this can take
more than two seconds).

in some platforms, we found the max-read-request-size in Device Control
Register is set to 0 by (BIOS?) during bootup, this will cause the

Restore it to a min-value.
register definition of REG_DEVICE_CTRL is removed, using kernel API to
access it as it's a standard pcie register.

tipc: introduce publication lists struct
There is currently a single list that is containing both cluster-scope and
zone-scope publications, and the list count is a separate free floating
variable. Create a struct to bind the count to the list, and to pave
the way for factoring out the publications into zone/cluster/node scope.
The current "publ_root" most matches what will be the cluster scope
list, so it is named accordingly in this commit.

batman-adv: skip the window protection test when the originator has no neighbours
When we receive an OGM from from a node for the first time, the last_real_seqno
field of the orig_node structure has not been initialised yet. The value of this
field is used to compute the current ogm-seqno window and therefore the
protection mechanism will probably drop the packet due to an out-of-window error.
To avoid this situation this patch adds a check to skip the window protection
mechanism if no neighbour nodes have already been added. When the first
neighbour node is added, the last_real_seqno field is initialised too.
