In tg3_setup_copper_phy(), if autonegotiation is disabled, we need to
relink only if the speed or duplex does not match the configured
setting. If flow control does not match, a relink is not necessary as
flow control is not a PHY setting. Later on, we'll call
tg3_setup_flow_ctrl() to set up the MAC to the desired flow control
settings if we're in full duplex mode.

Receiving unhandled notifications is most certainly not an error
and should not be logged as one. Knowing that the device sends
notifications we don't handle is useful for developers, but there
is very little a user can do about this. The message is therefore
just annoying noise to most users with devices sending unhandled
notifications like e.g. USB_CDC_NOTIFY_RESPONSE_AVAILABLE

recently many new supports have been added in the stmmac driver w/o taking care
about where each new field had to be placed inside the private structure for
guaranteeing the best cache usage.
This is what I wanted in the beginning, so this patch reorganizes all the fields
in order to keep adjacent fields for cache effect.
I have also tried to optimize them by using pahole.
V2: do not abuse with ____cacheline_aligned_in_smp and keep fields that
potentially could stay in the same cache-line for better usage in SMP systems.

Using DT for mdiobus and ethernet-phy requires to know the PHY address, which
is hard to guess if you don't know it. This patch extends of_mdiobus_register
to scan mdiobus for PHYs if reg property of the corresponding node is not set.
This also allows to have phy nodes in SoC DT files where the reg property can
be overwritten in the board file later. To encourage people to finally set the
actual phy address, the mdiobus scan is noisier than required.

It served no purpose: we never call it from anywhere in the stack

This reverts commit 0ef1594c017521ea89278e80fe3f80dafb17abde.
This patch introduced a few races which cannot be easily fixed with a
small follow-up patch. Furthermore, the SoC with the broken hardware
register, which this patch intended to add support for, can only be used
with device trees, which this driver currently does not support.

We have a race condition if we try to rmmod bonding and simultaneously add
a bond master through sysfs. In bonding_exit() we first remove the devices
(through rtnl_link_unregister() ) and only after that we remove the sysfs.
If we manage to add a device through sysfs after that the devices were
removed - we'll end up with that device/sysfs structure and with the module
unloaded.
Fix this by first removing the sysfs and only after that calling
rtnl_link_unregister().

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless into wireless
John W. Linville says:
====================
Here are some more fixes intended for the 3.9 stream...
Regarding the mac80211 bits, Johannes says:
"I had changed the idle handling to simplify it, but broken the
sequencing of commands, at least for ath9k-htc, one patch restores the
sequence. The other patch fixes a crash Jouni found while stress-testing
the remain-on-channel code, when an item is deleted the work struct can
run twice and crash the second time."
As for the iwlwifi bits, Johannes says:
"The only fix here is to the passive-no-RX firmware regulatory
enforcement driver support code to not drop auth frames in quick
succession, leading to not being able to connect to APs on passive
channels in certain circumstances."
Don't forget the NFC bits, about which Samuel says:
"This time we have:
- A crash fix for when a DGRAM LLCP socket is listening while the NFC adapter
is physically removed.
- A potential double skb free when the LLCP socket receive queue is full.
- A fix for properly handling multiple and consecutive LLCP connections, and
not trash the socket ack log.
- A build failure for the MEI microread physical layer, now that the MEI bus
APIs have been merged into char-misc-next."
On top of that, Stone Piao provides an mwifiex fix to avoid accessing
beyond the end of a buffer.
