This reverts commit 4386f566 ("net: ethernet: bcmgenet: use
phy_ethtool_{get|set}_link_ksettings")

This patch is wrong, the function phy_ethtool_{get|set}_link_ksettings
don't check if the device is running, but the driver bcmgenet need this
check.

The function {get|set}_settings need to access the mdio bus, and this
bus may only be used when the device is running. Otherwise, the clock
is disable and a mdio access will fail.

The bcma portion of the driver has been split off into a bcma specific
driver.  This has been mirrored for the platform driver.  The last
references to the bcma core struct have been changed into a generic
function call.  These function calls are wrappers to either the original
bcma code or new platform functions that access the same areas via MMIO.
This necessitated adding function pointers for both platform and bcma to
hide which backend is being used from the generic bgmac code.

The bgmac driver is using the bcma provides device ID and revision, as
well as the SoC ID and package, to determine which features are
necessary to enable, reset, etc in the driver.   In anticipation of
removing the bcma requirement for this driver, these must be changed to
not reference that struct.  In place of that, each "feature" has been
given a flag, and the flags are enabled for their respective device and

Move the BCMA MDIO phy into a separate file, as it is very tightly
coupled with the BCMA bus.  This will help with the upcoming BCMA
removal from the bgmac driver.  Optimally, this should be moved into
phy drivers, but it is too tightly coupled with the bgmac driver to
effectively move it without more changes to the driver.

Note: the phy_reset was intentionally removed, as the mdio phy subsystem
automatically resets the phy if a reset function pointer is present.  In
addition to the moving of the driver, this reset function is added.

Beacon report radio measurement requires reporting observed BSSs
on the channels specified in the beacon request. If the measurement
mode is set to passive or active, it requires actually performing a
scan (passive or active, accordingly), and reporting the time that
the scan was started and the time each beacon/probe was received
(both in terms of TSF of the BSS of the requesting AP). If the
request mode is table, this information is optional.
In addition, the radio measurement request specifies the channel
dwell time for the measurement.

In order to use scan for beacon report when the mode is active or
passive, add a parameter to scan request that specifies the
channel dwell time, and add scan start time and beacon received time
to scan results information.

Supporting beacon report is required for Multi Band Operation (MBO).

We need to hold some private data for every neigh entry. It would be
possible to do it using neigh_priv_len/ndo_neigh_construct/
ndo_neigh_destroy however only for the port device itself. That would not
work for stacked devices like bridge/team/bond. So introduce a private
neigh table. Hook onto ndos neigh_construct/destroy and add/remove
table entry according to that.
