Davinci MDIO is always used as slave device which services
read/write requests from MDIO/PHY core. It doesn't use IRQ also.
As result, It's possible to relax PM runtime constraints for Davinci
MDIO and enable it on demand, instead of powering it during probe
and powering off during removal.
Hence, implement PM runtime autosuspend for Davinci MDIO, but keep it
disabled by default, because Davinci MDIO is integrated in big set of
TI devices and not all of them expected to work corectly with RPM
autosuspend enabled:
- expected to work on SoCs where MDIO is part of TI CPSW
(cpsw.c DRA7/am57x, am437x, am335x, dm814x)
- not verified on Keystone 2 and other SoCs where MDIO is used with TI EMAC IP
(davinci_emac.c: dm6467-emac, am3517-emac, dm816-emac).
Davinci MDIO RPM autosuspend can be enabled through sysfs:

Add PM runtime .runtime_suspend()/.runtime_resume() callbacks and
perform Davinci MDIO enabling/disabling from these callbacks. This
allows to reuse pm_runtime_force_suspend/resume() APIs during System
suspend and required for further implementation of PM runtime
autosuspend.

The Davinci MDIO MDIO_CONTROL.CLKDIV can be calculated only once
during probe, hence split __davinci_mdio_reset() on
davinci_mdio_init_clk() and davinci_mdio_enable(). Initialize and
save CLKDIV in .probe(). Then just use saved value.

It's not expected Davinci MDIO to be accessible after its suspend
callbacks have been called:
- all consumers of Davinci MDIO will stop/disconnect phys at Device
suspend stage;
- all phys are expected to be suspned already by PHY/MDIO core;
- MDIO locking is done by MDIO Bus code.
Hence, it's safe to drop "suspended" and "lock" fields from mdio_data.

The CPSW might be suspended by RPM if all ethX interfaces are down,
but it still could be accesible through net_device_ops interfce. In
this case net_device_ops operations requiring registers access will
cause L3 errors and CPSW crash.
Hence, fix it by adding RPM get/put calls in net_device_ops callbacks
which need to access CPSW registers: .ndo_set_mac_address(),
.ndo_vlan_rx_add_vid(), .ndo_vlan_rx_kill_vid().

PM runtime is properly handled in cpsw_ndo_open/stop(), as result it
isn't required to duplicate these calls in .suspend()/.resume()
callbacks. Moreover, it might cause unnecessary RPM resume of CPSW
during System suspend in the case it's already suspended because
all ethX interfaces are down already, before System suspend started.

The cpsw_suspend() could trigger L3 error and CPSW will stop
functioning if System enters suspend when all ethX net-devices are
down - in this case CPSW could be already suspended by PM runtime, but
cpsw_suspend() will try to call soft_reset_slave() unconditionally
and access CPSW registers.
Hence, fix it by moving soft_reset_slave() from cpsw_suspend() to
cpsw_slave_stop(). This way slave ports will be reset when CPSW is
active and will be in proper state during Suspend.

stmmac: rework and enhance the PCS support
The 3.xx and 4.xx synopsys gmacs have a very similar
PCS embedded module and they share almost the same registers;
for example:
AN_Control, AN_Status, AN_Advertisement, AN_Link_Partner_Ability,
AN_Expansion, TBI_Extended_Status.
Just the RGMII/SMII Control/Status register differs.
So these patches aim to reorganize and enhance the PCS support;
to do that, some small inline functions have been provided and
also some rework to the PCS ISR part has been done.
In the end, the SGMII for MAC2MAC connection has been introduced.
All patches have been built on top of net-next git and, as for
the previous version, not fully tested.

In case of SGMII more, for example when a MAC2MAC connection
is needed, the port selection bits (inside the MAC configuration
registers) have to be programmed according to the link selected.
So the patch adds a new DT parameter to pass the port selection
and to programmed related PCS and CORE to use it.

By default, all gmac cores disable the PCS block and always
enable the PMT.
Note that this is done in a different way by 3.x and 4.x cores.
With this rework, PCS and PMT interrupt masks can be driven by
parameters now moved inside the mac_device_info structure
and the settings follow what the HW capability register reports.

The proc connector messages include a sequence number, allowing userspace
programs to detect lost messages. However, performing this detection is
currently more difficult than necessary, since netlink messages can be
delivered to the application out-of-order. To fix this, leave pre-emption
disabled during cn_netlink_send(), and use GFP_NOWAIT.
The following was written as a test case. Building the kernel w/ make -j32
proved a reliable way to generate out-of-order cn_proc messages.

The bridge is falsly dropping ipv6 mulitcast packets if there is:
1. No ipv6 address assigned on the brigde.
2. No external mld querier present.
3. The internal querier enabled.
When the bridge fails to build mld queries, because it has no
ipv6 address, it slilently returns, but keeps the local querier enabled.
This specific case causes confusing packet loss.
Ipv6 multicast snooping can only work if:
a) An external querier is present
OR
b) The bridge has an ipv6 address an is capable of sending own queries
Otherwise it has to forward/flood the ipv6 multicast traffic,
because snooping cannot work.
This patch fixes the issue by adding a flag to the bridge struct that
indicates that there is currently no ipv6 address assinged to the bridge
and returns a false state for the local querier in
__br_multicast_querier_exists().
Special thanks to Linus Lüssing.

If a user space program (e.g., wpa_supplicant) deletes a STA entry that
is currently in NL80211_PLINK_ESTAB state, the number of established
plinks counter was not decremented and this could result in rejecting
new plink establishment before really hitting the real maximum plink
limit. For !user_mpm case, this decrementation is handled by
mesh_plink_deactive().
Fix this by decrementing estab_plinks on STA deletion
(mesh_sta_cleanup() gets called from there) so that the counter has a
correct value and the Beacon frame advertisement in Mesh Configuration
element shows the proper value for capability to accept additional
peers.

Calling the fixed-phy functions when CONFIG_FIXED_PHY=m as a previous
change tried cannot work if the caller is in built-in code:
drivers/of/built-in.o: In function `of_phy_register_fixed_link':
of_reserved_mem.c:(.text+0x85e0): undefined reference to `fixed_phy_register'
Making of_mdio depend on 'FIXED_PHY || !FIXED_PHY' would solve this
dependency by enforcing that OF_MDIO itself becomes a loadable module
when FIXED_PHY=y, but that creates a different dependency as it
breaks any built-in ethernet driver that uses of_mdio.
Making FIXED_PHY a bool option also cannot work, since it depends on
PHYLIB, which again is tristate.
This version now uses 'select FIXED_PHY' to ensure that the fixed-phy
portion of of_mdio is not optional. The main downside of this is
a small increase in code size for cases that do not need fixed phy
support, but it should avoid all of the link-time problems.

Since commit 7bb11dc9f59d ("bonding: unify all places where
actor-oper key needs to be updated."), the logic in bonding to handle
selection between multiple aggregators has not functioned.
This affects only configurations wherein the bonding slaves
connect to two discrete aggregators (e.g., two independent switches, each
with LACP enabled), thus creating two separate aggregation groups within a
single bond.
The cause is a change in 7bb11dc9f59d to no longer set
AD_PORT_BEGIN on a port after a link state change, which would cause the
port to be reselected for attachment to an aggregator as if were newly
added to the bond. We cannot restore the prior behavior, as it
contradicts IEEE 802.1AX 5.4.12, which requires ports that "become
inoperable" (lose carrier, setting port_enabled=false as per 802.1AX
5.4.7) to remain selected (i.e., assigned to the aggregator). As the port
now remains selected, the aggregator selection logic is not invoked.
A side effect of this change is that aggregators in bonding will
now contain ports that are link down. The aggregator selection logic
does not currently handle this situation correctly, causing incorrect
aggregator selection.
This patch makes two changes to repair the aggregator selection
logic in bonding to function as documented and within the confines of the
standard:
First, the aggregator selection and related logic now utilizes the
number of active ports per aggregator, not the number of selected ports
(as some selected ports may be down). The ad_select "bandwidth" and
"count" options only consider ports that are link up.
Second, on any carrier state change of any slave, the aggregator
selection logic is explicitly called to insure the correct aggregator is
active.

The test_fp_ctl function is used to test if a given value is a valid
floating-point control. The inline assembly in test_fp_ctl uses an
incorrect constraint for the 'orig_fpc' variable. If the compiler
chooses the same register for 'fpc' and 'orig_fpc' the test_fp_ctl()
function always returns true. This allows user space to trigger
kernel oopses with invalid floating-point control values on the
signal stack.

each time the PF changed its promiscuity.

Always add MAC address at the tail of the MAC filter list. Since the
device's "real" MAC address is added first, it will always be at the
beginning of the list. This prevents an issue where the "real" MAC
filter might not get added if too many other filters are added before
bringing the interface up.

Limiting qcount to pf->num_lan_msix, effectively limits the RSS queues
to only use the number of CPUs, and ignore all other queues. We don't
want to do this. If the user has changed the RSS settings to use more
queues then CPUS, we want to trust they know what they are doing and
let them. More importantly, if we tell them that is what we did, we want
to actually do it and allow traffic into all of the queues we have
allocated. This does not change the default setting to initially
allocate only the number of CPUS of queue pairs.

When a Direct Attach (DA) cable is used, if the i40e_set_settings
function is called it would return an error. Add the DA type so
the function won't fail.

The i40e_suspend() function was failing to save PCI state
and this would result in a kernel stack trace from a WARN_ONCE in the
pci_legacy_suspend() function.
Add a call to pci_save_state() to fix that problem.

The i40e_suspend() function calls another function that preps the device
for the power save and resume by freeing all the Tx/Rx resources and
interrupts but that function does not free the "other" causes interrupt
vector and IRQ. It also fails to call synchronize_irq() before freeing
the IRQ vectors. This sometimes may result in some AER errors on those
systems with that PCIe error reporting feature enabled.
Call synchronize_irq() before freeing IRQ vectors and explicitly free
the other causes interrupt resources and shut down that MSIX interrupt.

If the user adds an obscene amount of MAC addresses, the driver will run
into the situation where it has too many address requests to fit into a
single PF message. The driver checks for this case, and calculates the
maximum number of messages that it can send. Then it completely ignores
this count and overflows the buffer.
Fix this by checking the address count and bailing out of the loop at
the appropriate time.

We were failing to set the client interface down when we put the VSI
down. Add this call so that the client doesn't get an open called with
no close.
Also remove an un-needed delay. The VF should not be affected at all by
i40e_down.
