====================
This series contains updates to ixgbe and igb.
The ixgbe changes contains 2 patches from the community, one which is a
fix from akepner to fix a issue where netif_running() in shutdown was
not done under rtnl_lock. The other community fix from Joe Perches
cleans up #ifdef CONFIG_DEBUG_FS which is no longer necessary. The
last ixgbe patch, from Jacob Keller, adds support for WoL on 82559
SFP+ LOM.
The remaining patches are against igb, 10 of which were previously
submitted in a pull request where changes were requested.
The following igb patches:
igb: Support for 100base-fx SFP
igb: Support to read and export SFF-8472/8079 data
are v2 based on feedback from Dan Carpenter and Ben Hutchings in
the previous pull request.
The largest set of changes are in my patch to cleanup code comments
and whitespace to align the igb driver with the networking style of
code comments. While cleaning up the code comments, fixed several
other whitespace/checkpatch.pl code formatting issues.
Other notable igb patches are EEE capable devices query the PHY to
determine what the link partner is advertising, added support for
i354 devices and added support for spoofchk config.

====================
This series contains updates to ixgbe only.
v2- Dropped the following 2 patches from the series:
ixgbe: Support using build_skb in the case that jumbo frames are disabled
ixgbe: walk pci-e bus to find minimum width
Ben Hutchings found a bug with Alex's patch, so that patch was dropped
permanently. Jacob's "walk PCIe bus" patch is being re-worked for
a more generic solution so that other drivers can benefit.
In the remaining patches...
Alex provides a fix where we were incorrectly checking the entire frag_off
field when we only wanted the fragment offset. Alex also cleans up
the check for PAGE_SIZE, since the default configuration allocates 32K
for all buffers.
Emil provides a change to the calculation of eerd so that it is consistent
between the read and write functions by using | instead of +.
Jacob adds support for displaying PCIe Gen3 link speed, which was
previously missing from the ixgbe driver. He also provides a patch
to clean up ixgbe_get_bus_info_generic to call some conversion
functions, which are used also in another patch provided by Jacob.
Jacob modifies the driver to enable certain devices (which have an
internal switch) to read from the physical slot rather than reading
data from the internal switch.
Don provides a couple of fixes (which are more appropriate for net-next),
one of which resolves an issue where ixgbe was only turning on the laser
when the adapter was up which caused issues for those who wanted to
access the MNG firmware while the port was in a down state. The other
fix is for WoL when currently linked at 1G. Lastly Don bumps the driver
version keep the in-kernel driver up to date with the current functionality.

Its not clear right now if we could avoid this in the first place :
- We could arm RTO timer not at the time we enqueue packets, but
at the time we TX complete them (tcp_wfree())
- Cancel the sending of the new copy of the packet if prior one

Merge branch 'tipc-ipoib'
Patrick McHardy says:
====================
The following patchset adds support for running TIPC over InfiniBand.
The patchset consists of three parts (+ a minor fix for the ethernet media
type):
- Preparation: removal of an the unused str2addr callback and move of the
bcast_addr from struct tipc_media to struct tipc_bearer. This is necessary
because InfiniBand doesn't have a fixed broadcast address like ethernet,
so it needs to be initialized with the device's broadcast address when
the bearer is enabled
- Introduction of a TIPC InfiniBand media type. A new media type is needed
to deal with the different address sizes
- Support for ETH_P_TIPC in IPoIB
Since the last posting I've addressed all feedback I received and rebased
to the current net-next tree.
I consider these patches ready for merging. Since they mainly affect TIPC
code, I'd propose to have them either go through the TIPC tree or through
Dave directly (not sure how TIPC patches are managed).

IPoIB: add support for TIPC protocol
Support TIPC in the IPoIB driver. Since IPoIB now keeps track of its own
neighbour entries and doesn't require the packet to have a dst_entry
anymore, the only necessary changes are to:
- not drop multicast TIPC packets because of the unknown ethernet type
- handle unicast TIPC packets similar to IPv4/IPv6 unicast packets
in ipoib_start_xmit().
An alternative would be to remove all ethertype limitations since they're
not necessary anymore, all TIPC needs to know about is ARP and RARP since
it wants to always perform "path find", even if a path is already known.

tipc: add InfiniBand media type
Add InfiniBand media type based on the ethernet media type.
The only real difference is that in case of InfiniBand, we need the entire
20 bytes of space reserved for media addresses, so the TIPC media type ID is
not explicitly stored in the packet payload.

sctp: Add buffer utilization fields to /proc/net/sctp/assocs
This patch adds the following fields to /proc/net/sctp/assocs output:
- sk->sk_wmem_alloc as "wmema" (transmit queue bytes committed)
- sk->sk_wmem_queued as "wmemq" (persistent queue size)
- sk->sk_sndbuf as "sndbuf" (size of send buffer in bytes)
- sk->sk_rcvbuf as "rcvbuf" (size of receive buffer in bytes)
When small DATA chunks containing 136 bytes data are sent the TX_QUEUE
(assoc->sndbuf_used) reaches a maximum of 40.9% of sk_sndbuf value when
peer.rwnd = 0. This was diagnosed from sk_wmem_alloc value reaching maximum
value of sk_sndbuf.
TX_QUEUE (assoc->sndbuf_used), sk_wmem_alloc and sk_wmem_queued values are
incremented in sctp_set_owner_w() for outgoing data chunks. Having access to
the above values in /proc/net/sctp/assocs will provide a better understanding
of SCTP buffer management.

The current implementation of dev_uc_sync/unsync() assumes that there is
a strict 1-to-1 relationship between the source and destination of the sync.
In other words, once an address has been synced to a destination device, it
will not be synced to any other device through the sync API.
However, there are some virtual devices that aggreate a number of lower
devices and need to sync addresses to all of them. The current
API falls short there.
This patch introduces a new dev_uc_sync_multiple() api that can be called
in the above circumstances and allows sync to work for every invocation.

tcp: GSO should be TSQ friendly
I noticed that TSQ (TCP Small queues) was less effective when TSO is
turned off, and GSO is on. If BQL is not enabled, TSQ has then no
effect.
It turns out the GSO engine frees the original gso_skb at the time the
fragments are generated and queued to the NIC.
We should instead call the tcp_wfree() destructor for the last fragment,
to keep the flow control as intended in TSQ. This effectively limits
the number of queued packets on qdisc + NIC layers.

net: mv643xx_eth: add shared clk and cleanup existing clk handling
This patch adds an optional shared block clock to avoid lockups on
clock gated controllers. Besides the new clock, clock handling for
existing clocks is cleaned up and moved to devm_clk_get. Device
tree binding documentation is updated for the new clocks property.

vhost_net: remove tx polling state
After commit
2b8b328b61c799957a456a5a8dab8cc7dea68575 (vhost_net: handle polling
errors when setting backend), we in fact track the polling state through
poll->wqh, so there's no need to duplicate the work with an extra
vhost_net_polling_state. So this patch removes this and make the code simpler.
This patch also removes the all tx starting/stopping code in tx path according
to Michael's suggestion.
Netperf test shows almost the same result in stream test, but gets improvements
on TCP_RR tests (both zerocopy or copy) especially on low load cases.
Tested between multiqueue kvm guest and external host with two direct
connected 82599s.
