During shutdown it's possible for __dev_close() (which holds
rtnl_lock) to clear the __LINK_STATE_START bit, and for ixgbe
to then read that bit (without holding rtnl_lock), and then
not fail to free irqs, etc. The result is a crash like this:

====================
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.

Host queues (Qdisc + NIC) can hold packets so long that TCP can
eventually retransmit a packet before the first transmit even left
the host.

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
  is still in queue.

This patch adds instrumentation so that we can at least see how
often this problem happens.

TCPSpuriousRtxHostQueues SNMP counter is incremented every time
we detect the fast clone is not yet freed in tcp_transmit_skb()

We reset during the shutdown path which will reset AUTOC register.  This
would change LMS to 10G.  If we were currently linked at 1G we will lose
link, which is a bad thing if we wanted WoL to work.  For the fix I needed
to know if WoL is supported so I created a new bool in the ixgbe_hw struct.
If this is set we will not allow the reset to change the current LMS value

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).
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

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.

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.

 * Simplification of locking. It immediately makes things simpler to

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.

With patch applied, example output when peer.rwnd = 0

the work has been scheduled from interrupt, and not been
cancelled when the driver is unloaded, which doesn't remove
the work item from the global workqueue. call the
cancel_work_sync when the driver is removed (rmmod'ed).
