net: phy: add device-type abstraction
This series adds device and device-type abstractions to the micrel
driver, and enables support for RMII-reference clock selection for
KSZ8081 and KSZ8091 devices.
While adding support for more features for the Micrel PHYs mentioned
above, it became apparent that the configuration space is much too large
and that adding type-specific callbacks will simply not scale. Instead I
added a driver_data field to struct phy_device, which can be used to
store static device type data that can be parsed and acted on in
generic driver callbacks. This allows a lot of duplicated code to be
removed, and should make it much easier to add new features or deal with
device-type quirks in the future.
The series has been tested on a dual KSZ8081 setup. Further testing on
other Micrel PHYs would be much appreciated.
The recent commit a95a18afe4c8 ("phy/micrel: KSZ8031RNL RMII clock
reconfiguration bug") currently prevents KSZ8031 PHYs from using the
generic config-init. Bruno, who is the author of that patch, has agreed
to test this series and some follow-up diagnostic patches to determine
how best to incorporate these devices as well. I intend to send a
follow-up patch that removes the custom 8031 config-init and documents
this quirk, but the current series can be applied meanwhile.
These patches are against net-next which contains some already merged
prerequisite patches to the driver.

Add "micrel,rmii-reference-clock-select-25-mhz" to Micrel ethernet PHY
binding documentation.
This property is needed to properly describe some revisions of Micrel
PHYs which has the function of this configuration bit inverted so that
setting it enables 25 MHz rather than 50 MHz clock mode.
Note that a clock reference ("rmii-ref") is still needed to actually
select either mode.

Micrel KSZ8081 and KSZ8091 PHYs have the RMII Reference Clock Select
bit, which is used to select 25 or 50 MHz clock mode.
Note that on some revisions of the PHY (e.g. KSZ8081RND) the function of
this bit is inverted so that setting it enables 25 rather than 50 MHz
mode. Add a new device-tree property

Add generic RMII-Reference-Clock-Select support.
Several Micrel PHY have an RMII-Reference-Clock-Select bit to select
25 MHz or 50 MHz clock mode. Recently, support for configuring this
through device tree for KSZ8021 and KSZ8031 was added.
Generalise this support so that it can be configured for other PHY types
as well.
Note that some PHY revisions (of the same type) has this bit inverted.
This should be either configurable through a new device-tree property,
or preferably, determined based on PHY ID if possible.
Also note that this removes support for setting 25 MHz mode from board
files which was also added by the above mentioned commit 45f56cb82e45

This fixes an old regression introduced by commit
b0d0d915 (ipx: remove the BKL).
When a recvmsg syscall blocks waiting for new data, no data can be sent on the
same socket with sendmsg because ipx_recvmsg() sleeps with the socket locked.
This breaks mars-nwe (NetWare emulator):
- the ncpserv process reads the request using recvmsg
- ncpserv forks and spawns nwconn
- ncpserv calls a (blocking) recvmsg and waits for new requests
- nwconn deadlocks in sendmsg on the same socket
Commit b0d0d915 has simply replaced BKL locking with
lock_sock/release_sock. Unlike now, BKL got unlocked while
sleeping, so a blocking recvmsg did not block a concurrent
sendmsg.
Only keep the socket locked while actually working with the socket data and
release it prior to calling skb_recv_datagram().

Overloading the msg_size field in the arq_event_info struct is just a
bad idea. It leads to repeated bugs when the structure is used in a
loop, since the input value (buffer size) is overwritten by the output
value (actual message length).
Fix this by splitting the field into two and renaming to indicate the
actual function of each field.
Since the arq_event struct has now changed, we need to change the drivers
to support this. Note that we no longer need to initialize the buffer size
each time we go through a loop as this value is no longer destroyed by
arq processing.
In the process, we also fix a bug in i40evf_verify_api_ver where the
buffer size was not correctly reinitialized each time through the loop.

Existing code updates cupfreq policy only while executing
cpufreq_apply_cooling() function (i.e. when notify_device != NOTIFY_INVALID).
It doesn't apply constraints when cpufreq policy update happens from any other
place but it should update the cpufreq policy with thermal constraints every
time when there is a cpufreq policy update, to keep state of
cpufreq_cooling_device and max_feq of cpufreq policy in sync. For instance
while resuming cpufreq updates cpufreq_policy and it restores default
policy->usr_policy values irrespective of cooling device's cpufreq_state since
notification gets missed because (notify_device == NOTIFY_INVALID).
Another problem, is that userspace is able to change max_freq irrespective of
cooling device's state, as notification gets missed.
This patch modifies code to maintain a global cpufreq_dev_list and applies
constraints of all matching cooling devices for policy's cpu when there is any
policy update(ends up applying the lowest max_freq among the matching cpu
cooling devices).
This patch also removes redundant check (max_freq > policy->user_policy.max),
as cpufreq framework takes care of user_policy constraints already where ever
required, otherwise its causing an issue while increasing max_freq in normal
scenerio as it restores max_freq with policy->user_policy.max which is old
(smaller) value.

Johannes Berg <johannes@sipsolutions.net> says:
"It has been a while since my last pull request, so we accumulated
another relatively large set of changes:
* TDLS off-channel support set from Arik/Liad, with some support
patches I did
* custom regulatory fixes from Arik
* minstrel VHT fix (and a small optimisation) from Felix
* add back radiotap vendor namespace support (myself)
* random MAC address scanning for cfg80211/mac80211/hwsim (myself)
* CSA improvements (Luca)
* WoWLAN Net Detect (wake on network found) support (Luca)
* and lots of other smaller changes from many people"

snd_nativeinstruments_control_get() uses a stack as a buffer for
usb_control_msg(), but it's basically not allowed. Replace the call
with a safer helper, snd_usb_ctl_msg(), instead.
