If we are managing IPv6 addresses using DHCP, it would be nice
for user-space to be notified if an address configured through
DHCP fails DAD. Otherwise user-space would have to poll to see

This patch uses the existing notification mechanism and simply

Some network devices, particularly USB ones, take several seconds to
fully init and appear in the device list.
If the user turned ipconfig on, they are using it for NFS root or some
other early booting purpose. So it makes no sense to just flat out
fail immediately if the device isn't found.
It also doesn't make sense to just jack up the initial wait to
something crazy like 10 seconds.
Instead, poll immediately, and then periodically once a second,
waiting for a usable device to appear. Fail after 12 seconds.

I discovered that if EMBEDDED=y, one can accidentally build a mac80211 stack
and drivers w/ no rate control algorithm. For drivers like RTL8187 that don't
supply their own RC algorithms, this will cause ieee80211_register_hw to
fail (making the driver unusable).
This will tell kconfig to provide a warning if no rate control algorithms
have been selected. That'll at least warn the user; users that know that
their drivers supply a rate control algorithm can safely ignore the
warning, and those who don't know (or who expect to be using multiple
drivers) can select a default RC algorithm.

The current software scan implemenation in mac80211 returns to the operating
channel after each scanned channel. However, in some situations (e.g. no
traffic) it would be nicer to scan a few channels in a row to speed up
the scan itself.
Hence, after scanning a channel, check if we have queued up any tx frames and
return to the operating channel in that case.
Unfortunately we don't know if the AP has buffered any frames for us. Hence,
scan only as many channels in a row as the pm_qos latency and the negotiated
listen interval allows us to.

Port commit 20deb48d16fdd07ce2fdc8d03ea317362217e085
from git://tipc.cslab.ericsson.net/pub/git/people/allan/tipc.git
Part of the large effort I'm trying to help with getting all the downstreamed
code from windriver forward ported to the upstream tree
Origional commit message
Restore check to filter out inadverdently received messages
This patch reimplements a check that allows TIPC to discard messages
that are not intended for it. This check was present in TIPC 1.5/1.6,
but was removed by accident during the development of TIPC 1.7; it has
now been updated to account for new features present in TIPC 1.7 and
reinserted into TIPC. The main benefit of this check is to filter
out messages arriving from orphaned link endpoints, which can arise
when a node exits the network and then re-enters it with a different
TIPC network address (i.e. <Z.C.N> value).

Remove htohl implementation from tipc
I was working on forward porting the downstream commits for TIPC and ran accross this one:
http://tipc.cslab.ericsson.net/cgi-bin/gitweb.cgi?p=people/allan/tipc.git;a=commitdiff;h=894279b9437b63cbb02405ad5b8e033b51e4e31e
I was going to just take it, when I looked closer and noted what it was doing.
This is basically a routine to byte swap fields of data in sent/received packets
for tipc, dependent upon the receivers guessed endianness of the peer when a
connection is established. Asside from just seeming silly to me, it appears to
violate the latest RFC draft for tipc:
http://tipc.sourceforge.net/doc/draft-spec-tipc-02.txt
Which, according to section 4.2 and 4.3.3, requires that all fields of all
commands be sent in network byte order. So instead of just taking this patch,
instead I'm removing the htohl function and replacing the calls with calls to
ntohl in the rx path and htonl in the send path.
As part of this fix, I'm also changing the subscr_cancel function, which
searches the list of subscribers, using a memcmp of the entire subscriber list,
for the entry to tear down. unfortunately it memcmps the entire tipc_subscr
structure which has several bits that are private to the local side, so nothing
will ever match. section 5.2 of the draft spec indicates the <type,upper,lower>
tuple should uniquely identify a subscriber, so convert subscr_cancel to just
match on those fields (properly endian swapped).
I've tested this using the tipc test suite, and its passed without issue.

We added an automatic route cache rebuilding in commit 1080d709fb
but had to correct few bugs. One of the assumption of original patch,
was that entries where kept sorted in a given way.
This assumption is known to be wrong (commit 1ddbcb005c gave an
explanation of this and corrected a leak) and expensive to respect.
Paweł Staszewski reported to me one of his machine got its routing cache
disabled after few messages like :
[ 2677.850065] Route hash chain too long!
[ 2677.850080] Adjust your secret_interval!
[82839.662993] Route hash chain too long!
[82839.662996] Adjust your secret_interval!
[155843.731650] Route hash chain too long!
[155843.731664] Adjust your secret_interval!
[155843.811881] Route hash chain too long!
[155843.811891] Adjust your secret_interval!
[155843.858209] vlan0811: 5 rebuilds is over limit, route caching
disabled
[155843.858212] Route hash chain too long!
[155843.858213] Adjust your secret_interval!
This is because rt_intern_hash() might be fooled when computing a chain
length, because multiple entries with same keys can differ because of
TOS (or mark/oif) bits.
In the rare case the fast algorithm see a too long chain, and before
taking expensive path, we call a helper function in order to not count
duplicates of same routes, that only differ with tos/mark/oif bits. This
helper works with data already in cpu cache and is not be very
expensive, despite its O(N^2) implementation.
Paweł Staszewski sucessfully tested this patch on his loaded router.

This is part of the ops structure constification
effort started by Arjan van de Ven et al.
Benefits of this constification:
* prevents modification of data that is shared
(referenced) by many other structure instances
at runtime
* detects/prevents accidental (but not intentional)
modification attempts on archs that enforce
read-only kernel data at runtime
* potentially better optimized code as the compiler
can assume that the const data cannot be changed
* the compiler/linker move const data into .rodata
and therefore exclude them from false sharing

Also drivers can extend the attributes with own data fields

Debatable -- the current comment is located at the callsite of
ops->get_sset_count(), which is where an implementor might think to add

Hence the "some" in the attached patch to include/linux/ethtool.h,
