The phy_init_hw() function may reset the PHY to a configuration
that does not match manual network settings stored in the phydev
structure. If the phy state machine is polled rather than event
driven this can create a timing hazard where the phy state machine
might alter the settings stored in the phydev structure from the
value read from the BMCR.
This commit follows invocations of phy_init_hw() by the bcmgenet
driver with invocations of the genphy_config_aneg() function to
ensure that the BMCR is written to match the settings held in the
phydev structure. This prevents the risk of manual settings being
accidentally altered.

This reverts commit 1f515486275a08a17a2c806b844cca18f7de5b34.
This commit improved the chances of the umac resetting cleanly by
ensuring that the PHY was restored to its normal operation prior
to resetting the umac. However, there were still cases when the
PHY might not be driving a Tx clock to the umac during this window
(e.g. when the PHY detects no link).
The previous commit now ensures that the unimac receives clocks
from the MAC during its reset window so this commit is no longer
needed. This commit also has an unintended negative impact on the
MDIO performance of the UniMAC MDIO interface because it is used
before the MDIO interrupts are reenabled, so it should be removed.

As noted in commit 28c2d1a7a0bf ("net: bcmgenet: enable loopback
during UniMAC sw_reset") the UniMAC must be clocked while sw_reset
is asserted for its state machines to reset cleanly.
The transmit and receive clocks used by the UniMAC are derived from
the signals used on its PHY interface. The bcmgenet MAC can be
configured to work with different PHY interfaces including MII,
GMII, RGMII, and Reverse MII on internal and external interfaces.
Unfortunately for the UniMAC, when configured for MII the Tx clock
is always driven from the PHY which places it outside of the direct
control of the MAC.
The earlier commit enabled a local loopback mode within the UniMAC
so that the receive clock would be derived from the transmit clock
which addressed the observed issue with an external GPHY disabling
it's Rx clock. However, when a Tx clock is not available this
loopback is insufficient.
This commit implements a workaround that leverages the fact that
the MAC can reliably generate all of its necessary clocking by
enterring the external GPHY RGMII interface mode with the UniMAC in
local loopback during the sw_reset interval. Unfortunately, this
has the undesirable side efect of the RGMII GTXCLK signal being
driven during the same window.
In most configurations this is a benign side effect as the signal
is either not routed to a pin or is already expected to drive the
pin. The one exception is when an external MII PHY is expected to
drive the same pin with its TX_CLK output creating output driver
contention.
This commit exploits the IEEE 802.3 clause 22 standard defined
isolate mode to force an external MII PHY to present a high
impedance on its TX_CLK output during the window to prevent any
contention at the pin.
The MII interface is used internally with the 40nm internal EPHY
which agressively disables its clocks for power savings leading to
incomplete resets of the UniMAC and many instabilities observed
over the years. The workaround of this commit is expected to put
an end to those problems.

Before this change of_get_phy_mode() returned an enum,
phy_interface_t. On error, -ENODEV etc, is returned. If the result of
the function is stored in a variable of type phy_interface_t, and the
compiler has decided to represent this as an unsigned int, comparision
with -ENODEV etc, is a signed vs unsigned comparision.
Fix this problem by changing the API. Make the function return an
error, or 0 on success, and pass a pointer, of type phy_interface_t,
where the phy mode should be stored.
v2:
Return with *interface set to PHY_INTERFACE_MODE_NA on error.

We call bnxt_ulp_stop() to notify the RDMA driver that some error or
imminent reset is about to happen. After that we always call
some variants of bnxt_close().
In the next patch, we will integrate the recently added error
recovery with the RDMA driver. In response to ulp_stop, the
RDMA driver may free MSIX vectors and that will also trigger
bnxt_close(). To avoid bnxt_close() from being called twice,
we set a new flag after ulp_stop is called. If the RDMA driver
frees MSIX vectors while the new flag is set, we will not call
bnxt_close(), knowing that it will happen in due course.
With this change, we must make sure that the bnxt_close() call
after ulp_stop will reset IRQ. Modify bnxt_reset_task()
accordingly if we call ulp_stop.

The decap (VXLAN tunnel) flow rules are not getting offloaded with
upstream kernel. This is because TC block callback infrastructure has
been updated to use indirect callbacks to get offloaded rules from
other higher level devices (such as tunnels), instead of ndo_setup_tc().
Since the decap rules are applied to the tunnel devices (e.g, vxlan_sys),
the driver should register for indirect TC callback with tunnel devices
to get the rules for offloading. This patch updates the driver to
register and process indirect TC block callbacks from VXLAN tunnels.

Driver supports 2 types of core dumps.
1. Live dump - Firmware dump when system is up and running.
2. Crash dump - Dump which is collected during firmware crash
that can be retrieved after recovery.
Crash dump is currently supported only on specific 58800 chips
which can be retrieved using OP-TEE API only, as firmware cannot
access this region directly.
User needs to set the dump flag using following command before
initiating the dump collection:
$ ethtool -W|--set-dump eth0 N
Where N is "0" for live dump and "1" for crash dump
Command to collect the dump after setting the flag:
$ ethtool -w eth0 data Filename
v3: Modify set_dump to support even when CONFIG_TEE_BNXT_FW=n.
Also change log message to netdev_info().

The EPHY integrated into the 40nm Set-Top Box devices can falsely
detect energy when connected to a disabled peer interface. When the
peer interface is enabled the EPHY will detect and report the link
as active, but on occasion may get into a state where it is not
able to exchange data with the connected GENET MAC. This issue has
not been observed when the link parameters are auto-negotiated;
however, it has been observed with a manually configured link.
It has been empirically determined that issuing a soft reset to the
EPHY when energy is detected prevents it from getting into this bad
state.

It turns out that the "Workaround for putting the PHY in IDDQ mode"
used by the internal EPHYs on 40nm Set-Top Box chips when powering
down puts the interface to the GENET MAC in a state that can cause
subsequent MAC resets to be incomplete.
Rather than restore the forced soft reset when powering up internal
PHYs, this commit moves the invocation of phy_init_hw earlier in
the MAC initialization sequence to just before the MAC reset in the
open and resume functions. This allows the interface to be stable
and allows the MAC resets to be successful.
The bcmgenet_mii_probe() function is split in two to accommodate
this. The new function bcmgenet_mii_connect() handles the first
half of the functionality before the MAC initialization, and the
bcmgenet_mii_config() function is extended to provide the remaining
PHY configuration following the MAC initialization.

pci/0000:af:00.0:
name fw_fatal
state healthy error 1 recover 1 grace_period 0 auto_recover true
Fatal events from firmware or missing periodic heartbeats will
be reported and recovery will be handled.
We also turn on the support flags when we register with the firmware to
enable this health and recovery feature in the firmware.

This call will handle fatal firmware errors by forcing a reset on the
firmware. The master function driver will carry out the forced reset.
The sequence will go through the same bnxt_fw_reset_task() workqueue.
This fatal reset differs from the non-fatal reset at the beginning
stages. From the BNXT_FW_RESET_STATE_ENABLE_DEV state onwards where
the firmware is coming out of reset, it is practically identical to the
non-fatal reset.
The next patch will add the periodic heartbeat check and the devlink
reporter to report the fatal event and to initiate the bnxt_fw_exception()
call.

This state handles driver initiated chip reset during error recovery.
Only the master function will perform this step during error recovery.
The next patch will add code to initiate this reset from the master
function.

Add a flag to mark that the firmware has encountered fatal condition.
The driver will not send any more firmware messages and will return
error to the caller. Fix up some clean up functions to continue
and not abort when the firmware message function returns error.
This is preparation work to fully handle firmware error recovery
under fatal conditions.

Add devlink health reporter for the firmware reset event. Once we get
the notification from firmware about the impending reset, the driver
will report this to devlink and the call to bnxt_fw_reset() will be
initiated to complete the reset sequence.
