When handling IP fragmented packets with csum in their
transport header, the csum isn't changed as part of the
fragmentation. As a result, the packet containing the
transport headers would have the correct csum of the original
packet, but one that mismatches the actual packet that
passes on the wire. As a result, on receive path HW would
give an indication that the packet has incorrect csum,
which would cause qede to discard the incoming packet.
Since HW also delivers a notification of IP fragments,
change driver behavior to pass such incoming packets
to stack and let it make the decision whether it needs
to be dropped.

switch to use tx skb array in tun
This series tries to switch to use skb array in tun. This is used to
eliminate the spinlock contention between producer and consumer. The
conversion was straightforward: just introdce a tx skb array and use
it instead of sk_receive_queue.
A minor issue is to keep the tx_queue_len behaviour, since tun used to
use it for the length of sk_receive_queue. This is done through:
- add the ability to resize multiple rings at once to avoid handling
partial resize failure for mutiple rings.
- add the support for zero length ring.
- introduce a notifier which was triggered when tx_queue_len was
changed for a netdev.
- resize all queues during the tx_queue_len changing.
Tests shows about 15% improvement on guest rx pps:
Before: ~1300000pps
After : ~1500000pps
Changes from V3:
- fix kbuild warnings
- call NETDEV_CHANGE_TX_QUEUE_LEN on IFLA_TXQLEN
Changes from V2:
- add multiple rings resizing support for ptr_ring/skb_array
- add zero length ring support
- introdce a NETDEV_CHANGE_TX_QUEUE_LEN
- drop new flags
Changes from V1:
- switch to use skb array instead of a customized circular buffer
- add non-blocking support
- rename .peek to .peek_len
- drop lockless peeking since test show very minor improvement

efficient since it requires spinlocks to synchronize between producer

This patch tries to address this by:
- switch from sk_receive_queue to a skb_array, and resize it when
tx_queue_len was changed.
- introduce a new proto_ops peek_len which was used for peeking the
skb length.
- implement a tun version of peek_len for vhost_net to use and convert
vhost_net to use peek_len if possible.

HFSC patches, part 1
It's revised version of part of the patches I submitted really, really long
time ago (back then I asked Patrick to ignore them as I found some issues
shortly after submitting).
Anyway this is the first set with very simple fixes/changes though some of them
relatively subtle (I tried to do very exhaustive commit messages explaining what
and why with those).
The patches are against net-next tree.
The second set will be heavier - or rather with more complex explanations, among those I have:
- a fix to subtle issue introduced in
http://permalink.gmane.org/gmane.linux.kernel.commits.2-4/8281
along with simplifying related stuff
- update times to 96 bits (which allows to "just" use 32 bit shifts and
improves curve definition accuracy at more extreme low/high speeds)
- add curve "merging" instead of just selecting in convex case (computations
mirror those from concave intersection)
But these are eventually for later.

When a class is going passive, it should update its cl_vt first
to be consistent with the last dequeue operation.
Otherwise its cl_vt will be one packet behind and parent's cvtmax might
not be updated as well.
One possible side effect is if some class goes passive and subsequently
goes active /without/ its parent going passive - with cl_vt lagging one
packet behind - comparison made in init_vf() will be affected (same
period).

Realtime scheduling implemented in HFSC uses head of the queue to make
the decision about which packet to schedule next. But in case of any
head drop, the deadline calculated for the previous head is not
necessarily correct for the next head (unless both packets have the same
length).
Thanks to peek() function used during dequeue - which internally is a
dequeue operation - hfsc is almost safe from this issue, as peek()
dequeues and isolates the head storing it temporarily until the real
dequeue happens.
But there is one exception: if after the class activation a drop happens
before the first dequeue operation, there's never a chance to do the
peek().
Adding peek() call in enqueue - if this is the first packet in a new
backlog period AND the scheduler has realtime curve defined - fixes that
one corner case. The 1st hfsc_dequeue() will use that peeked packet,
similarly as every subsequent hfsc_dequeue() call uses packet peeked by
the previous call.

- m_start() in fs/namespace.c expects that ns->event is incremented each
time a mount added or removed from ns->list.
- umount_tree() removes items from the list but does not increment event
counter, expecting that it's done before the function is called.
- There are some codepaths that call umount_tree() without updating
"event" counter. e.g. from __detach_mounts().
- When this happens m_start may reuse a cached mount structure that no
longer belongs to ns->list (i.e. use after free which usually leads
to infinite loop).
This change fixes the above problem by incrementing global event counter
before invoking umount_tree().

Pull MFD fixes from Lee Jones:
"Contained are some standard fixes and unusually an extension to the
Reset API. Some of those changes are required to fix a bug introduced
in -rc1, which introduces extra 'reset line checks' i.e. whether the
line is shared or not. If a line is shared and the new *_shared() API
is not used, the request fails with an error. This breaks USB in v4.7
for ST's platforms.
Admittedly, there are some patches contained in our (MFD/Reset)
immutable branch which are not true -fixes, but there isn't anything I
can do about that. Rest assured though, there aren't any API
'changes'. Everything is the same from the consumer's perspective.
- Use new reset_*_get_shared() variant to prevent reset line
obtainment failure (Fixes commit 0b52297f22: "reset: Add support
for shared reset controls")
- Fix unintentional switch() fall-through into error path
- Fix uninitialised variable compiler warning"

Intel Wired LAN Driver Updates 2016-06-29
This series contains updates and fixes to e1000e, igb, ixgbe and fm10k. A
true smorgasbord of changes.
Jake cleans up some obscurity by not using the BIT() macro on bitshift
operation and also fixed the calculated index when looping through the
indir array. Fixes the issue with igb's workqueue item for overflow
check from causing a surprise remove event. The ptp_flags variable is
added to simplify the work of writing several complex MAC type checks
in the PTP code while fixing the workqueue.
Alex Duyck fixes the receive buffers alignment which should not be L1
cache aligned, but to 512 bytes instead.
Denys Vlasenko prevents a division by zero which was reported under
VMWare for e1000e.
Amritha fixes an issue where filters in a child hash table must be
cleared from the hardware before delete the filter links in ixgbe.
Bhaktipriya Shridhar simply replaces the deprecated create_workqueue()
with alloc_workqueue() for fm10k.
Tony corrects ixgbe ethtool reporting to show x550 supports hardware
timestamping of all packets.
Emil fixes an issue where MAC-VLANs on the VF fail to pass traffic due
to spoofed packets.
Andrew Lunn increases performance on some systems where syncing a buffer
for DMA is expensive. So rather than sync the whole 2K receive buffer,
only synchronize the length of the frame.

nfp: few code improvements
Three small patches for net-next. First and second patches
improve the code quality by spelling things correctly and
removing unused parameters. Third patch hooks-in standard
kernel implementation of .get_link() in ethtool ops.
