When shutting down the NIC, we shutdown async event processing before
freeing all the rings.  If there is a link change event during reset, the
driver may miss it and the link state may be incorrect after the NIC is
re-opened.  Poll the link at the end of __bnxt_open_nic() to get the
correct link status.

The purpose of gigaset_device_release() is to kfree() the struct
ser_cardstate that contains our struct device. This is done via a bit of
a detour. First we make our struct device's driver_data point to the
container of our struct ser_cardstate (which is a struct cardstate). In
gigaset_device_release() we then retrieve that driver_data again. And
after that we finally kfree() the struct ser_cardstate that was saved in
the struct cardstate.

All of this can be achieved much easier by using container_of() to get
from our struct device to its container, struct ser_cardstate. Do so.

Note that at the time the detour was implemented commit b8b2c7d8
("base/platform: assert that dev_pm_domain callbacks are called
unconditionally") had just entered the tree. That commit disconnected
our platform_device and our platform_driver. These were reconnected
again in v4.5-rc2 through commit 25cad69f ("base/platform: Fix
platform drivers with no probe callback"). And one of the consequences
of that fix was that it broke the detour via driver_data. That's because
it made __device_release_driver() stop being a NOP for our struct device
and actually do stuff again. One of the things it now does, is setting
our driver_data to NULL. That, in turn, makes it impossible for
gigaset_device_release() to get to our struct cardstate. Which has the
net effect of leaking a struct ser_cardstate at every call of this
driver's tty close() operation. So using container_of() has the
additional benefit of actually working.

When I used netdev_for_each_lower_dev in commit bad53162 ("vrf:
remove slave queue and private slave struct") I thought that it acts
like netdev_for_each_lower_private and can be used to remove the current
device from the list while walking, but unfortunately it acts more like
netdev_for_each_lower_private_rcu and doesn't allow it. The difference
is where the "iter" points to, right now it points to the current element
and that makes it impossible to remove it. Change the logic to be
similar to netdev_for_each_lower_private and make it point to the "next"
element so we can safely delete the current one. VRF is the only such
user right now, there's no change for the read-only users.

This avoids a harmless randconfig warning I get when USB_NET_CDC_SUBSET
is enabled, but all of the more specific drivers are not:

drivers/net/usb/cdc_subset.c:241:2: #warning You need to configure some hardware for this driver

The current behavior is clearly intentional, giving a warning when
a user picks a configuration that won't do anything good. The only
reason for even addressing this is that I'm getting close to
eliminating all 'randconfig' warnings on ARM, and this came up
a couple of times.

My workaround is to not even build the module when none of the
configurations are enable.

Alternatively we could simply remove the #warning (nothing wrong
for compile-testing), turn it into a runtime warning, or
change the Kconfig options into a menu to hide CONFIG_USB_NET_CDC_SUBSET.

My implementation around IFF_NO_QUEUE driver flag assumed that leaving
tx_queue_len untouched (specifically: not setting it to zero) by drivers
would make it possible to assign a regular qdisc to them without having
to worry about setting tx_queue_len to a useful value. This was only
partially true: I overlooked that some drivers don't call ether_setup()
and therefore not initialize tx_queue_len to the default value of 1000.
Consequently, removing the workarounds in place for that case in qdisc
implementations which cared about it (namely, pfifo, bfifo, gred, htb,
plug and sfb) leads to problems with these specific interface types and
qdiscs.

Luckily, there's already a sanitization point for drivers setting
tx_queue_len to zero, which can be reused to assign the fallback value
most qdisc implementations used, which is 1.

With commit 0071f56e ("dsa: Register netdev before phy"), we are now trying
to free a network device that has been previously registered, and in case of
errors, this will make us hit the BUG_ON(dev->reg_state != NETREG_UNREGISTERED)
condition.

Fix this by adding a missing unregister_netdev() before free_netdev().

For the Marvell 88E1510, marvell_of_reg_init was called too late, in the
config_aneg function.
Since commit 113c74d8 ("net: phy: turn carrier off on phy attach"),
this lead to the link not coming up at boot anymore, due to the phy
state machine being stuck at waiting for interrupts (off by default on
the 88E1510).
For seven other Marvell PHYs, marvell_of_reg_init was not called at all.

Add a generic marvell_config_init function, which in turn calls
marvell_of_reg_init.
PHYs, which already have a specific config_init function with a call to
marvell_of_reg_init, are left untouched. The generic marvell_config_init
function is called for all the others, to get consistent behavior across
all Marvell PHYs.

The example in the DT binding documentation uses the preliminary DT
bindings for the r8a7795 MSTP clocks, which never went upstream.
Update the example to use the DT bindings for the upstream Clock Pulse
Generator / Module Standby and Software Reset hardware block.

When a VLAN device leaves a bridge its STP state is set to DISABLED,
which causes the hardware to discard any packets coming through the port
with this VLAN.

Fix that by setting STP state to FORWARDING when the device leaves its
bridge and allow traffic to be directed to CPU.
