16626b0cc3 asix: Add a new driver for the AX88172A
The Asix AX88172A is a USB 2.0 Ethernet interface that supports both an
internal PHY as well as an external PHY (connected via MII).

This patch adds a driver for the AX88172A and provides support for
both modes and the phylib.

5a308f40bf 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    +->
+       +   +  xmit  +  + skb orphaning +  + propagation     +
+-------+   +--------+  +---------------+  +-----------------+
      < rate limiting >                  < delay, drops, reorders >

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.

ac1ae5f33f be2net: dont pull too much data in skb linear part
skb_fill_rx_data() pulls 64 byte of data in skb->data

Its too much for TCP (with no options) on IPv4, as total size of headers
is 14 + 40 = 54

This means tcp stack and splice() are suboptimal, since tcp payload
is in part in tcp->data, and in part in skb frag.

f0396f60d7 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).

5e96855fc5 6lowpan: Change byte order when storing/accessing to len field

As it is currently written, the len field would not be decoded properly on an implementation using the correct byte ordering. Hence, it could lead to interroperability issues.

Also, I rewrote the code so that iphc0 argument of lowpan_alloc_new_frame could be removed.

141e369de6 xfrm: Initialize the struct xfrm_dst behind the dst_enty field
We start initializing the struct xfrm_dst at the first field
behind the struct dst_enty. This is error prone because it
might leave a new field uninitialized. So start initializing
the struct xfrm_dst right behind the dst_entry.

921a678cb6 Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next
John Linville says:

====================
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."

Finally, this includes another pull of the fixes from the wireless
tree in order to resolve some merge issues.

869dd4662f tipc: remove print_buf and deprecated log buffer code
The internal log buffer handling functions can now safely be
removed since there is no code using it anymore.  Requests to
interact with the internal tipc log buffer over netlink (in
config.c) will report 'obsolete command'.

This represents the final removal of any references to a
struct print_buf, and the removal of the struct itself.
We also get rid of a TIPC specific Kconfig in the process.

Finally, log.h is removed since it is not needed anymore.

dc1aed37d1 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.

e2dbd60134 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
