netem: refine early skb orphaning
netem does an early orphaning of skbs. Doing so breaks TCP Small Queue
or any mechanism relying on socket sk_wmem_alloc feedback.
Ideally, we should perform this orphaning after the rate module and
before the delay module, to mimic what happens on a real link :
skb orphaning is indeed normally done at TX completion, before the
transit on the link.

+ Qdisc +---> Device +--> TX completion +--> links / hops +->

If netem is used without delay feature (drops, reorders, rate
limiting), then we should avoid early skb orphaning, to keep pressure
on sockets as long as packets are still in qdisc queue.
Ideally, netem should be refactored to implement delay module
as the last stage. Current algorithm merges the two phases
(rate limiting + delay) so its not correct.

ipv6: fix RTPROT_RA markup of RA routes w/nexthops
Userspace implementations of network routing protocols sometimes need to
tell RA-originated IPv6 routes from other kernel routes to make proper
routing decisions. This makes most sense for RA routes with nexthops,
namely, default routes and Route Information routes.
The intended mean of preserving RA route origin in a netlink message is
through indicating RTPROT_RA as protocol code. Function rt6_fill_node()
tried to do that for default routes, but its test condition was taken
wrong. This change is modeled after the original mailing list posting
by Jeff Haran. It fixes the test condition for default route case and
sets the same behaviour for Route Information case (both types use
nexthops). Handling of the 3rd RA route type, Prefix Information, is
left unchanged, as it stands for interface connected routes (without
nexthops).

Several drivers see updates: mwifiex, ath9k, iwlwifi, brcmsmac,
wlcore/wl12xx/wl18xx, and a handful of others. The bcma bus got a
lot of attention from Hauke Mehrtens. The cfg80211 component gets
a flurry of patches for multi-channel support, and the mac80211
component gets the first few VHT (11ac) and 60GHz (11ad) patches.
This also includes the removal of the iwmc3200 drivers, since the
hardware never became available to normal people.
Additionally, the NFC subsystem gets a series of updates. According to
Samuel, "Here are the interesting bits:
- A better error management for the HCI stack.
- An LLCP "late" binding implementation for a better NFC SAP usage. SAPs are
now reserved only when there's a client for it.
- Support for Sony RC-S360 (a.k.a. PaSoRi) pn533 based dongle. We can read and
write NFC tags and also establish a p2p link with this dongle now.
- A few LLCP fixes."

tipc: phase out most of the struct print_buf usage
The tipc_printf is renamed to tipc_snprintf, as the new name
describes more what the function actually does. It is also
changed to take a buffer and length parameter and return
number of characters written to the buffer. All callers of
this function that used to pass a print_buf are updated.
Final removal of the struct print_buf itself will be done
synchronously with the pending removal of the deprecated
logging code that also was using it.
Functions that build up a response message with a list of
ports, nametable contents etc. are changed to return the number
of characters written to the output buffer. This information
was previously hidden in a field of the print_buf struct, and
the number of chars written was fetched with a call to
tipc_printbuf_validate. This function is removed since it
is no longer referenced nor needed.
A generic max size ULTRA_STRING_MAX_LEN is defined, named
in keeping with the existing TIPC_TLV_ULTRA_STRING, and the
various definitions in port, link and nametable code that
largely duplicated this information are removed. This means
that amount of link statistics that can be returned is now
increased from 2k to 32k.
The buffer overflow check is now done just before the reply
message is passed over netlink or TIPC to a remote node and
the message indicating a truncated buffer is changed to a less
dramatic one (less CAPS), placed at the end of the message.

tipc: simplify print buffer handling in tipc_printf
tipc_printf was previously used both to construct debug traces
and to append data to buffers that should be sent over netlink
to the tipc-config application. A global print_buffer was
used to format the string before it was copied to the actual
output buffer. This could lead to concurrent access of the
global print_buffer, which then had to be lock protected.
This is simplified by changing tipc_printf to append data
directly to the output buffer using vscnprintf.
With the new implementation of tipc_printf, there is no longer
any risk of concurrent access to the internal log buffer, so
the lock (and the comments describing it) are no longer
strictly necessary. However, there are still a few functions
that do grab this lock before resizing/dumping the log
buffer. We leave the lock, and these functions untouched since
they will be removed with a subsequent commit that drops the
deprecated log buffer handling code

net: Update alloc frag to reduce get/put page usage and recycle pages
This patch is meant to help improve performance by reducing the number of

This is accomplished by using atomic_set operations on the page count
instead of calling get_page and put_page. It is based on work originally
provided by Eric Dumazet.
In addition it also helps to reduce memory overhead when using TCP. This
is done by recycling the page if the only holder of the frame is the
netdev_alloc_frag call itself. This can occur when skb heads are stolen by
either GRO or TCP and the driver providing the packets is using paged frags
to store all of the data for the packets.

net: add support for NS8390 based eth controllers on some ColdFire CPU boards
A number of older ColdFire CPU based boards use NS8390 based network
controllers. Most use the Davicom 9008F or the UMC 9008F. This driver
provides the support code to get these devices working on these platforms.
Generally the NS8390 based eth device is direct connected via the general
purpose bus of the ColdFire CPU. So its addressing and interrupt setup is
fixed on each of the different platforms (classic platform setup).
This driver is based on the other drivers/net/ethernet/8390 drivers, and
includes the lib8390.c code. It uses the existing definitions of the
board NS8390 device addresses, interrupts and access types from the
arch/m68k/include/asm/mcf8390.h, but moves the IO access functions into
the driver code and out of that header.

m68knommu: move the badly named mcfne.h to a better mcf8390.h
The mcfne.h include contains definitions to support NS8390 eth based hardware
on ColdFire based CPU boards. So change its name to reflect that better.

tipc: limit error messages relating to memory leak to one line
With the default name table size of 1024, it is possible that
the sanity check in tipc_nametbl_stop could spam out 1024
essentially identical error messages if memory was corrupted
or similar. Limit it to issuing no more than a single message.
The actual chain number (i.e. 0 --> 1023) wouldn't provide any
useful insight if/when such an instance happened, so don't
bother printing out that value.

tipc: factor stats struct out of the larger link struct
This is done to improve readability, and so that we can give

Merge branch 'redirect_via_sock'
As described in my patch series from the other day, we need to
rearrange redirect handling so that the local initiators of packets
(sockets, tunnels, xfrms, etc.) that implement the protocols compute
the route and pass this down into the ipv4/ipv6 routing code.
These changes here do so by implementing a new dst_ops->redirect
method.
No more do we have this funny code that tries several different sets
of routing keys to try and figure out which route the redirect should
actually be applied to.
No more do we have the problem wherein TOS rewriting causes problems
for us.
