This patch will add the msgbuf protocol. This protocol is used by
the soon to be added new bus interface PCIe. Msgbuf is a protocol
where most data is and remains located on the host (driver) side
and transferred by DMA from and to device. Msgbuf is the protocol
which takes care of the signalling of the buffers between host and
device which identifies this DMA-able data.

The Micrel ksz9021 PHY does not support standard IEEE standard MMD
extended register access, therefore requires stubs to fail the read
register method and do nothing for the write register method when
libphy attempts to read and/or configure Energy Efficient Ethernet
features in PHYS that do support those features. This problem
was observed on an Altera Cyclone V SOC development kit that
uses the Synopsys EMAC and the Micrel ksz9021 PHY. This patch
was tested on the same board, and Energy Efficient Ethernet is
now disabled as expected since the Micrel PHY does not support that
feature.

libphy was originally written assuming all phy devices support clause 45
access extensions to the mmd registers through the indirection registers
located within the first 16 phy registers. This assumption is not true
in all cases, and one specific example is the Micrel ksz9021 10/100/1000
Mbps phy. Using the stmmac driver, accessing the mmd registers to query
and configure energy efficient Ethernet (EEE) features yielded unexpected
behavior.
This patch adds mmd access functions to the phy driver that can be
overriden by the phy specific driver if the phy does not support this
mechanism or uses it's own non-standard access mechanism. By default,
the IEEE Compatible clause 45 access mechanism described in clause 22
is used. With this patch, EEE query/configure functions as expected
using the stmmac and the Micrel ksz9021 phy.

sk_unattached_filter_destroy() does not always need to release the
filter object via rcu. Since this filter is never attached to the
socket, the caller should be responsible for releasing the filter
in a safe way, which may not necessarily imply rcu.
This is a short summary of clients of this function:
1) xt_bpf.c and cls_bpf.c use the bpf matchers from rules, these rules
are removed from the packet path before the filter is released. Thus,
the framework makes sure the filter is safely removed.
2) In the ppp driver, the ppp_lock ensures serialization between the
xmit and filter attachment/detachment path. This doesn't use rcu
so deferred release via rcu makes no sense.
3) In the isdn/ppp driver, it is called from isdn_ppp_release()
the isdn_ppp_ioctl(). This driver uses mutex and spinlocks, no rcu.
Thus, deferred rcu makes no sense to me either, the deferred releases
may be just masking the effects of wrong locking strategy, which
should be fixed in the driver itself.
4) In the team driver, this is the only place where the rcu
synchronization with unattached filter is used. Therefore, this
patch introduces synchronize_rcu() which is called from the
genetlink path to make sure the filter doesn't go away while packets
are still walking over it. I think we can revisit this once struct
bpf_prog (that only wraps specific bpf code bits) is in place, then
add some specific struct rcu_head in the scope of the team driver if
Jiri thinks this is needed.
Deferred rcu release for unattached filters was originally introduced
in 302d663 ("filter: Allow to create sk-unattached filters").

In preparation for a new mlx5 device which is VPI (i.e., ports can be
either IB or ETH), move the pci device functionality from mlx5_ib
to mlx5_core.
This involves the following changes:
1. Move mlx5_core_dev struct out of mlx5_ib_dev. mlx5_core_dev
is now an independent structure maintained by mlx5_core.
mlx5_ib_dev now has a pointer to that struct.
This requires changing a lot of places where the core_dev
struct was accessed via mlx5_ib_dev (now, this needs to
be a pointer dereference).
2. All PCI initializations are now done in mlx5_core. Thus,
it is now mlx5_core which does pci_register_device (and not
mlx5_ib, as was previously).
3. mlx5_ib now registers itself with mlx5_core as an "interface"
driver. This is very similar to the mechanism employed for
the mlx4 (ConnectX) driver. Once the HCA is initialized
(by mlx5_core), it invokes the interface drivers to do
their initializations.
4. There is a new event handler which the core registers:
mlx5_core_event(). This event handler invokes the
event handlers registered by the interfaces.

Mbit/s. However, the MVPP2_GMAC_CONFIG_MII_SPEED bit in the

- It never byte-swaps, but that doesn't make a difference now as PIO

- It doesn't include any memory barriers, but that's OK as there is a

Commit 87aa9f9c61 ("net: phy: consolidate PHY reset in phy_init_hw()")
moved the call to phy_scan_fixups() in phy_init_hw() after a software
reset is performed.
By the time phy_init_hw() is called in phy_device_register(), no driver
has been bound to this PHY yet, so all the checks in phy_init_hw()
against the PHY driver and the PHY driver's config_init function will
return 0. We will therefore never call phy_scan_fixups() as we should.
Fix this by calling phy_scan_fixups() and check for its return value to
restore the intended functionality.
This broke PHY drivers which do register an early PHY fixup callback to
intercept the PHY probing and do things like changing the 32-bits unique
PHY identifier when a pseudo-PHY address has been used, as well as
board-specific PHY fixups that need to be applied during driver probe
time.

and,
"Here follows some more patches for 3.17. These are mostly fixes to what
we've sent to you before for next merge window."
For the iwlwifi bits, Emmanuel says:
"I have the usual amount of BT Coex stuff. Arik continues to work

And for the Atheros bits, Kalle says:

version of ar6004.
For ath10k Janusz added a printout so that it's easier to check what
ath10k kconfig options are enabled. He also added a debugfs file to
configure maximum amsdu and ampdu values. Also we had few fixes as
usual."
On top of that is the usual large batch of various driver updates --

Rafał has also been very busy with b43 and related updates.

The sunvnet driver doesn't check whether or not a port is connected when
transmitting packets, which results in failures if a port fails to connect
(e.g., due to a version mismatch). The original code also assumes
unnecessarily that the first port is up and a switch, even though there is
a flag for switch ports.
This patch only matches a port if it is connected, and otherwise uses the
switch_port flag to send the packet to a switch port that is up.
