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.

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.

tcp: TCP Small Queues
This introduce TSQ (TCP Small Queues)
TSQ goal is to reduce number of TCP packets in xmit queues (qdisc &
device queues), to reduce RTT and cwnd bias, part of the bufferbloat
problem.
sk->sk_wmem_alloc not allowed to grow above a given limit,
allowing no more than ~128KB [1] per tcp socket in qdisc/dev layers at a
given time.
TSO packets are sized/capped to half the limit, so that we have two
TSO packets in flight, allowing better bandwidth use.
As a side effect, setting the limit to 40000 automatically reduces the
standard gso max limit (65536) to 40000/2 : It can help to reduce
latencies of high prio packets, having smaller TSO packets.
This means we divert sock_wfree() to a tcp_wfree() handler, to
queue/send following frames when skb_orphan() [2] is called for the
already queued skbs.
Results on my dev machines (tg3/ixgbe nics) are really impressive,
using standard pfifo_fast, and with or without TSO/GSO.
Without reduction of nominal bandwidth, we have reduction of buffering
per bulk sender :
< 1ms on Gbit (instead of 50ms with TSO)
< 8ms on 100Mbit (instead of 132 ms)
I no longer have 4 MBytes backlogged in qdisc by a single netperf
session, and both side socket autotuning no longer use 4 Mbytes.
As skb destructor cannot restart xmit itself ( as qdisc lock might be
taken at this point ), we delegate the work to a tasklet. We use one
tasklest per cpu for performance reasons.
If tasklet finds a socket owned by the user, it sets TSQ_OWNED flag.
This flag is tested in a new protocol method called from release_sock(),
to eventually send new segments.
[1] New /proc/sys/net/ipv4/tcp_limit_output_bytes tunable
[2] skb_orphan() is usually called at TX completion time,
but some drivers call it in their start_xmit() handler.
These drivers should at least use BQL, or else a single TCP
session can still fill the whole NIC TX ring, since TSQ will
have no effect.

Merge branch 'metrics_restructure'
This patch series works towards the goal of minimizing the amount
of things that can change in an ipv4 route.
In a regime where the routing cache is removed, route changes will
lead to cloning in the FIB tables or similar.
The largest trigger of route metrics writes, TCP, now has it's own
cache of dynamic metric state. The timewait timestamps are stored
there now as well.
As a result of that, pre-cowing metrics is no longer necessary,
and therefore FLOWI_FLAG_PRECOW_METRICS is removed.
Redirect and PMTU handling is moved back into the ipv4 routes. I'm
sorry for all the headaches trying to do this in the inetpeer has
caused, it was the wrong approach for sure.
Since metrics become read-only for ipv4 we no longer need the inetpeer
hung off of the ipv4 routes either. So those disappear too.
Also, timewait sockets no longer need to hold onto an inetpeer either.
After this series, we still have some details to resolve wrt. PMTU and
redirects for a route-cache-less system:
1) With just the plain route cache removal, PMTU will continue to
work mostly fine. This is because of how the local route users
call down into the PMTU update code with the route they already
hold.
However, if we wish to cache pre-computed routes in fib_info
nexthops (which we want for performance), then we need to add
route cloning for PMTU events.
2) Redirects require more work. First, redirects must be changed to
be handled like PMTU. Wherein we call down into the sockets and
other entities, and then they call back into the routing code with
the route they were using.
So we'll be adding an ->update_nexthop() method alongside
->update_pmtu().
And then, like for PMTU, we'll need cloning support once we start
caching routes in the fib_info nexthops.
But that's it, we can completely pull the trigger and remove the
routing cache with minimal disruptions.
As it is, this patch series alone helps a lot of things. For one,
routing cache entry creation should be a lot faster, because we no
longer do inetpeer lookups (even to check if an entry exists).
This patch series also opens the door for non-DST_HOST ipv4 routes,
because nothing fundamentally cares about rt->rt_dst any more. It
can be removed with the base routing cache removal patch. In fact,
that was the primary goal of this patch series.

r8169: support RTL8168G
For RTL8111G, the settings of phy and firmware are replaced with
ocp functions. r8168g_mdio_{write / read} redirects the relative
settings to suitable ocp functions. A per-device variable is needed
to evaluate the real address of ocp functions.
rtl_writephy(tp, 0x1f, xxxx) is dedicated to keeping said variable
up-to-date.

r8169: abstract out loop conditions.
Twelve functions can fail silently. Now they have a chance to complain.
Macro and pasting abuse has been kept at a level where tags and
friends should not be hurt.
