This change documents the 'mac-mode' property that was introduced in the
'stmmac' driver to support passive mode converters that can sit in-between
the MAC & PHY.

In-between the MAC & PHY there can be a mode converter, which converts one
mode to another (e.g. GMII-to-RGMII).
The converter, can be passive (i.e. no driver or OS/SW information
required), so the MAC & PHY need to be configured differently.
For the `stmmac` driver, this is implemented via a `mac-mode` property in
the device-tree, which configures the MAC into a certain mode, and for the
PHY a `phy_interface` field will hold the mode of the PHY. The mode of the
PHY will be passed to the PHY and from there-on it work in a different
mode. If unspecified, the default `phy-mode` will be used for both.

Currently frame registrations are not purged, even when changing the
interface type. This can lead to potentially weird situations where
frames possibly not allowed on a given interface type remain registered
due to the type switching happening after registration.
The kernel currently relies on userspace apps to actually purge the
registrations themselves, this is not something that the kernel should
rely on.
Add a call to cfg80211_mlme_purge_registrations() to forcefully remove
any registrations left over prior to switching the iftype.

When we expire an inactive station, try to send it a deauth. This
helps if it's actually still around, and just has issues with
beacon distribution (or we do), and it will not also remove us.
Then, if we have shared state, this may not be reset properly,
causing problems; for example, we saw a case where aggregation
sessions weren't removed properly (due to the TX start being
offloaded to firmware and it relying on deauth for stop), causing
a lot of traffic to get lost due to the SN reset after remove/add
of the peer.

In case we got a fw restart while roaming from encrypted AP to
non-encrypted one, we might end up with hitting a warning on the pending
counter crypto_tx_tailroom_pending_dec having a non-zero value.
The following comment taken from net/mac80211/key.c explains the rational
for the delayed tailroom needed:
/*
* The reason for the delayed tailroom needed decrementing is to
* make roaming faster: during roaming, all keys are first deleted
* and then new keys are installed. The first new key causes the
* crypto_tx_tailroom_needed_cnt to go from 0 to 1, which invokes
* the cost of synchronize_net() (which can be slow). Avoid this
* by deferring the crypto_tx_tailroom_needed_cnt decrementing on
* key removal for a while, so if we roam the value is larger than
* zero and no 0->1 transition happens.
*
* The cost is that if the AP switching was from an AP with keys
* to one without, we still allocate tailroom while it would no
* longer be needed. However, in the typical (fast) roaming case
* within an ESS this usually won't happen.
*/
The next flow lead to the warning eventually reported as a bug:
1. Disconnect from encrypted AP
2. Set crypto_tx_tailroom_pending_dec = 1 for the key
3. Schedule work
4. Reconnect to non-encrypted AP
5. Add a new key, setting the tailroom counter = 1
6. Got FW restart while pending counter is set ---> hit the warning
While on it, the ieee80211_reset_crypto_tx_tailroom() func was merged into
its single caller ieee80211_reenable_keys (previously called
ieee80211_enable_keys). Also, we reset the crypto_tx_tailroom_pending_dec
and remove the counters warning as we just reset both.

When the RFKILL subsystem isn't available, then rfkill_blocked()
always returns false. In the case of hardware rfkill this will
be wrong though, as if the hardware reported being killed then
it cannot operate any longer.
Since we only ever call the rfkill_sync work in this case, just
rename it to rfkill_block and always pass "true" for the blocked
parameter, rather than passing rfkill_blocked().
We rely on the underlying driver to still reject any new attempt
to bring up the device by itself.

nfp: implement firmware loading policy
Dirk says:
This series adds configuration capabilities to the firmware loading policy of
the NFP driver.
NFP firmware loading is controlled via three HWinfo keys which can be set per
device: 'abi_drv_reset', 'abi_drv_load_ifc' and 'app_fw_from_flash'.
Refer to patch #11 for more detail on how these control the firmware loading.
In order to configure the full extend of FW loading policy, a new devlink
parameter has been introduced, 'reset_dev_on_drv_probe', which controls if the
driver should reset the device when it's probed. This, in conjunction with the
existing 'fw_load_policy' (extended to include a 'disk' option) provides the
means to tweak the NFP HWinfo keys as required by users.
Patches 1 and 2 adds the devlink modifications and patches 3 through 9 adds the
support into the NFP driver. Furthermore, the last 2 patches are documentation
only.
v2:
Renamed all 'reset_dev_on_drv_probe' defines the same as the devlink parameter
name (Jiri)

This adds the initial documentation for the NFP driver specific
documentation.
Right now, only basic information is provided about acquiring firmware
and configuring device firmware loading.

Add support for the 'reset_dev_on_drv_probe' devlink parameter. The
reset control policy is controlled by the 'abi_drv_reset' hwinfo key.

Register devlink parameters for driver use. Subsequent patches will add
support for specific parameters.
In order to support devlink parameters, the management firmware needs to
be able to lookup and set hwinfo keys.

The firmware reset and loading policies can be controlled with the
combination of three hwinfo keys, 'abi_drv_reset', 'abi_drv_load_ifc'
and 'app_fw_from_flash'.
'app_fw_from_flash' defines which firmware should take precedence,
'Disk', 'Flash' or the 'Preferred' firmware. When 'Preferred'
is selected, the management firmware makes the decision on which
firmware will be loaded by comparing versions of the flash firmware
and the host supplied firmware.
'abi_drv_reset' defines when the driver should reset the firmware when
the driver is probed, either 'Disk' if firmware was found on disk,
'Always' reset or 'Never' reset. Note that the device is always reset
on driver unload if firmware was loaded when the driver was probed.
'abi_drv_load_ifc' defines a list of PF devices allowed to load FW on
the device.
Furthermore, we limit the cases to where the driver will unload firmware
again when the driver is removed to only when firmware was loaded by the
driver and only if this particular device was the only one that could
have loaded firmware. This is needed to avoid firmware being removed
while in use on multi-host platforms.
