In current mlx5e ndo_set_features implementation, setting some features
can success while others can fail. Today, we return one error code which
doesn't reflect the current features status of the netdev at the end of
the ndo callback.
Set netdev->features with features which were successfully set in order
to keep the current status in case of failure. For this purpose, define
new Macro to set/unset specific feature in netdev->features.
This patch introduces a mechanism that uses feature handlers for each
feature.
Set features will call a generic handler, which will then call a specific
handler in his turn and update netdev->features according to it's return
value. Each specific handler is responsible to perform driver specific
actions, and updating params if needed.

Redesign ethtool statistics handling and reporting in the driver:
1. Move counters to a separate file (en_stats.h).
2. Remove unnecessary dependencies between stats and strings.
3. Use counter descriptors which hold a name and offset for each counter,
and will be used to decide which counters will be exposed.
For example when adding a new software counter to ethtool, instead of:
1. Add to stats struct.
2. Add to strings struct in the same order.
3. Change macro defining number of software counters.
The only thing needed is to link the new counter to a counter descriptor.
VPort counters are a set of hardware traffic counters created automatically
for each virtual port opened.
PPort counters are a set of counters describing per physical port
performance statistics.

====================
net: core: remove TX_LOCKED support
Not that many users left, lets kill it.
TX_LOCKED was meant to be used by LLTX drivers when spin_trylock()
failed. Stack then re-queued if collisions happened on different
cpus or free'd the skb to prevent deadlocks.
Most of the driver removal patches fall into one of three categories:
1. remove the driver-private tx lock (and LLTX flag), or...
2. convert spin_trylock to plain spin_lock, or...
3. convert TX_LOCKED to free+TX_OK
Patches are grouped by these categories, last patch is the actual removal.

====================
ila: Support for checksum neutral translations
This patch set updates ILA to support draft-herbert-nvo3-ila-02. The
primary addition is support checksum neutral ILA translation.
This allows address to be performed and still keep any transport
layer checksums that include the addresses in their pseudo header to
still be correct without the translator needing to parse L4.
Other items are:
- Structures for ILA addresses, identifiers, locators
- Disallow translation on non-ILA addresses (check by
type in identifier).
- Change xlat (nf_input) to translates solely based
on matching locators not identifiers (since identifiers
are not obfuscated by checksum neutral).
- Side effect if above is that multiple ILA domains are
supported. Each local locator can map to a different
SIR address (ILA domain), and each domain defines its
own identifier space.
Tested: Ran TCP_RR with 200 cnxs. ILA performance is slightly better
than previously since we are not longer parsing L4 for checksum
handling. I amd seeing about 1% performance overhead. Also ran
TCP_STREAM and tested non-ILA address (type=0) are not translated.

Support checksum neutral ILA as described in the ILA draft. The low

The csum-mode parameter is added to described checksum processing. There

- adjust transport checksum (previous behavior)
- do checksum neutral mapping

On output the csum-mode in the ila_params is checked and acted on. If

On input, C-bit is checked. If it is set checksum-netural mapping is

Bluetooth: 6lowpan: Fix memory corruption of ipv6 destination address
The memcpy of ipv6 header destination address to the skb control block
(sbk->cb) in header_create() results in currupted memory when bt_xmit()
is issued. The skb->cb is "released" in the return of header_create()
making room for lower layer to minipulate the skb->cb.
The value retrieved in bt_xmit is not persistent across header creation
and sending, and the lower layer will overwrite portions of skb->cb,
making the copied destination address wrong.
The memory corruption will lead to non-working multicast as the first 4
bytes of the copied destination address is replaced by a value that
resolves into a non-multicast prefix.
This fix removes the dependency on the skb control block between header
creation and send, by moving the destination address memcpy to the send
function path (setup_create, which is called from bt_xmit).

skbuff: Add pskb_extract() helper function
A pattern of skb usage seen in modules such as RDS-TCP is to
extract `to_copy' bytes from the received TCP segment, starting
at some offset `off' into a new skb `clone'. This is done in
the ->data_ready callback, where the clone skb is queued up for rx on
the PF_RDS socket, while the parent TCP segment is returned unchanged
back to the TCP engine.
The existing code uses the sequence
clone = skb_clone(..);
pskb_pull(clone, off, ..);
pskb_trim(clone, to_copy, ..);
with the intention of discarding the first `off' bytes. However,
skb_clone() + pskb_pull() implies pksb_expand_head(), which ends
up doing a redundant memcpy of bytes that will then get discarded
in __pskb_pull_tail().
To avoid this inefficiency, this commit adds pskb_extract() that
creates the clone, and memcpy's only the relevant header/frag/frag_list
to the start of `clone'. pskb_trim() is then invoked to trim clone
down to the requested to_copy bytes.

the cacheline with __refcnt which had an unkown effect on performance. For
this reason, the pointer was kept in place for 64bit archs.
However, later performance measurements showed this is of no concern. It
turns out that every performance sensitive path that accesses lwtstate
accesses also struct rtable or struct rt6_info which share the same cache

qed: add support for link pause configuration.

qed*: Conditions for changing link
There's some inconsistency in current logic determining whether the
link settings of a given interface can be changed; I.e., in all modes
other than the so-called `deault' mode the interfaces are forbidden from
changing the configuration - but even this rule is not applied to all
user APIs that may change the configuration.
Instead, let the core-module [qed] decide whether an interface can change
the configuration by supporting a new API function. We also revise the
current rule, allowing all interfaces to change their configurations while
laying the infrastructure for future modes where an interface would be
blocked from making such a configuration.

Merge branch '10GbE' of git://git./linux/kernel/git/jkirsher/next-queue
Jeff Kirsher says:
====================
10GbE Intel Wired LAN Driver Updates 2016-04-25
This series contains updates to ixgbe and ixgbevf.
Emil provides several patches, starting with the consolidation of the
logic behind configuring spoof checking. Fixed an issue which was
causing link issues for backplane devices because x550em_a/x devices
did not have a default value for mac->ops.setup_link. Refactored the
ethtool stats to bring the logic closer to how ixgbe handles stats and
sets up per-queue stats for ixgbevf.
Mark adds a new register to wait for previous register writes to complete
before issuing a register read, which is needed when slower links are
in use. Fixed the flow control setup for x550em_a, the incorrect
fc_setup function was being used.
Don added a workaround for empty SFP+ cage crosstalk, since on some
systems the crosstalk could lead to link flap on empty SFP+ cages.
Jake converts ixgbe and ixgbevf to use the BIT() macro.
Alex Duyck adds support for partial GSO segmentation in the case of
tunnels for ixgbe and ixgbevf. Then preps for HyperV by moving the API
negotiation into mac_ops.
Arnd Bergmann provides a fix for the ARM compile warnings in linux-next
by converting the use of a udelay() to msleep().

netlink: align attributes when needed (patchset #2)
This is the continuation (series #2) of the work done to align netlink
attributes when these attributes contain some 64-bit fields.
In patch #3, I didn't modify the function ila_encap_nlsize(). I was waiting
feedback for this patch: http://patchwork.ozlabs.org/patch/613766/
If it's approved, there will be an update to switch nla_total_size() to
nla_total_size_64bit() after the merge of net in net-next.

The newly added x550em_a support causes a link failure on ARM because of
an overly long time passed into udelay():
ERROR: "__bad_udelay" [drivers/net/ethernet/intel/ixgbe/ixgbe.ko] undefined!
There are multiple variants of the ixgbe_acquire_swfw_sync_*() function,

callers are allowed to sleep, which makes msleep() a better replacement
