c5c351088a netns: fdb: allow unprivileged users to add/del fdb entries
Right now,only ixgdb,macvlan,vxlan and bridge implement
fdb_add/fdb_del operations.

these operations only operate the private data of net
device. So allowing the unprivileged users who creates
the userns and netns to add/del fdb entries will do no
harm to other netns.

bf414b369f net: usbnet: fix tx_dropped statistics
It is normal for minidrivers accumulating frames to return NULL
from their tx_fixup function. We do not want to count this as a
drop, or log any debug messages.  A different exit path is
therefore chosen for such drivers, skipping the debug message
and the tx_dropped increment.

The test for accumulating drivers was however completely bogus,
making the exit path selection depend on whether the user had
enabled tx_err logging or not. This would arbitrarily mess up
accounting for both accumulating and non-accumulating minidrivers,
and would result in unwanted debug messages for the accumulating
drivers.

Fix by testing for FLAG_MULTI_PACKET instead, which probably was
the intention from the beginning.  This usage match the documented
behaviour of this flag:

 Indicates to usbnet, that USB driver accumulates multiple IP packets.
 Affects statistic (counters) and short packet handling.

f76e39c531 x86/intel/cacheinfo: Shut up annoying warning
I've been getting the following warning when doing randbuilds
since forever. Now it finally pissed me off just the perfect
amount so that I can fix it.

  arch/x86/kernel/cpu/intel_cacheinfo.c:489:27: warning: ‘cache_disable_0’ defined but not used [-Wunused-variable]
  arch/x86/kernel/cpu/intel_cacheinfo.c:491:27: warning: ‘cache_disable_1’ defined but not used [-Wunused-variable] arch/x86/kernel/cpu/intel_cacheinfo.c:524:27: warning: ‘subcaches’ defined but not used [-Wunused-variable]

It happens because in randconfigs where CONFIG_SYSFS is not set,
the whole sysfs-interface to L3 cache index disabling is
remaining unused and gcc correctly warns about it. Make it
optional, depending on CONFIG_SYSFS too, as is the case with
other sysfs-related machinery in this file.

The ASM version of hash computation function was truncating the upper bit.
Make the ASM version similar to hpt_hash function. Remove masking vsid bits.
Without this patch, we observed hang during bootup due to not satisfying page
fault request correctly. The fault handler used wrong hash values to update
the HPTE. Hence we kept looping with page fault.

9665d5d624 packet: fix leakage of tx_ring memory
When releasing a packet socket, the routine packet_set_ring() is reused
to free rings instead of allocating them. But when calling it for the
first time, it fills req->tp_block_nr with the value of rb->pg_vec_len
which in the second invocation makes it bail out since req->tp_block_nr
is greater zero but req->tp_block_size is zero.

This patch solves the problem by passing a zeroed auto-variable to
packet_set_ring() upon each invocation from packet_release().

As far as I can tell, this issue exists even since 69e3c75 (net: TX_RING
and packet mmap), i.e. the original inclusion of TX ring support into
af_packet, but applies only to sockets with both RX and TX ring
allocated, which is probably why this was unnoticed all the time.

2e5f421211 tcp: frto should not set snd_cwnd to 0
Commit 9dc274151a (tcp: fix ABC in tcp_slow_start())
uncovered a bug in FRTO code :
tcp_process_frto() is setting snd_cwnd to 0 if the number
of in flight packets is 0.

As Neal pointed out, if no packet is in flight we lost our
chance to disambiguate whether a loss timeout was spurious.

We should assume it was a proper loss.

0231bb5336 perf: Fix event group context move
When we have group with mixed events (hw/sw) we want to end up
with group leader being in hw context. So if group leader is
initialy sw event, we move all the events under hw context.

The move is done for each event by removing it from its context
and adding it back into proper one. As a part of the removal the
event is automatically disabled, which is not what we want at
this stage of creating groups.

The fix is to initialize event state after removal from sw
context.

This fix resulted from the following discussion:

33397a7121 Merge branch 'delete-wanrouter' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux
Paul Gortmaker says:

====================
The removal of wanrouter code was originally listed in the (now
gone) feature removal file since May 2012, and an RFC of the
deletion was posted[1] in late 2012.  The overall concept was given
an OK, but defconfig contamination, build failures, etc. meant that
it didn't quite make it into mainline for 3.8.

Since that time, Dan discovered (via code audit) a runtime bug that
proves nobody has been using this for over four years[2].  With that
new information, I think it makes sense for someone to follow through
on Joe's original RFC and get this done for the 3.9 release.

In addition to resolving the build failures of the RFC by keeping
stub headers, this also splits the change into two parts, just like
the token ring removal did.  Part #1 decouples the mainline kernel
from the expired subsystem, and part #2 does the large scale
deletion of the subsystem content.

The advantage of the above, is that a "git blame" will never lead
you to a 4000+ line deletion commit.  The large scale deletion will
never show up in a "git blame" and hence the same advantages that we
get from the "--irreversible-delete" in the review stage of "git
format-patch" are also embedded into the git history itself.  This
may seem like a moot point to some, but for those who spend a
considerable amount of time data mining in the git history, this is
probably worth doing.

I have done build tests of all[mod/yes]config for both the stage 1
(Makefile and Kconfig) and stage 2 (full driver delete) as a sanity
check, and the issues with the previously posted RFC should be gone.

Speaking of "--irreversible-delete" -- these patches were created
with that option, so if you want to use them locally, you are going
to have to pull (location below) the content instead of doing a
"git am" of the mailed out content.

====================
This series contains updates to ixgbe and e1000e.  The ixgbe patches are
a mix of fixes, cleanup and added functionality.  The first fix is for
traffic classes, where if the mapping has changed reset the NIC.  The other
ixgbe fix resolves an issue where the device lookup neglected to do a
pci_dev_put() to decrement the device reference count.

The ixgbe cleanup was done by Josh, where the auto-negotiation variables
were renamed/cleaned up and refactored.

The remaining patches are from Bruce to do additional cleanup on e1000e as
well as bump the driver version.  Most notably is the cleanup to use the
kernel IEEE MII definitions where possible instead of the local MII
definitions.

d221ad1a8a rtlwifi: Fix many compile warnings when using W=1
Many warnings like the following arise from a build with W=1 on the
make line:

warning: comparison of unsigned expression >= 0 is always true [-Wtype-limits]

Changing the overall debug level storage from unsigned to signed fixes these.

62749238d1 mwifiex: do not reconfigure tx buffer size in firmware while associating
It's observed that reconfiguration of tx buffer size before
association can cause data path failure in firmware after
associated. Although this is only found with PCIe cards, but
potentially it could happen with any other interfaces as well.

The tx buffer reconfiguration is not really useful in firmware.
Let's remove it for all interfaces.

0255beda59 iwl4965: report A-MPDU status
This patch is based on "iwlwifi: report A-MPDU status".
(12bf6f45d1)

Since the firmware will give us an A-MPDU bit and
only a single PHY information packet for all the
subframes in an A-MPDU, we can easily report the
minimal A-MPDU information for radiotap.
