Fixes the issues with non BCM58XX chips in the b53 driver
failing, when the irq is not specified in the device tree.
Removed the check for BCM58XX in b53_srab_prepare_irq(),

Let genphy_c45_read_link manage the devices to check, this removes
overhead from callers. Add C22EXT to the list of excluded devices
because it doesn't implement the status register. According to the
802.3 clause 45 spec registers 29.0 - 29.4 are reserved.
At the moment we have very few clause 45 PHY drivers, so we are
lacking experience whether other drivers will have to exclude further
devices, or may need to check PHY XS. If we should figure out that
list of devices to check needs to be configurable, I think best will
be to add a device list member to struct phy_driver.

- adjusted commit message
- exclude also device C22EXT from link checking

When we add a new GENEVE device with IPv6 remote, checking only for
IS_ENABLED(CONFIG_IPV6) is not enough as we may disable IPv6 in the

cause a NULL pointer dereference.
v2:
- don't mix declarations and code (reported by Stefano Brivio, Eric Dumazet)
- there's no need to use in6_dev_get() as we only need to check that

With this patch, ndo_tx_timeout callback will be redirected to the tx
reporter in order to detect a tx timeout error and report it to the
devlink health. (The watchdog detects tx timeouts, but the driver verify
the issue still exists before launching any recover method).
In addition, recover from tx timeout in case of lost interrupt was added
to the tx reporter recover method. The tx timeout recover from lost
interrupt is not a new feature in the driver, this patch re-organize the
functionality and move it to the tx reporter recovery flow.

Add mlx5e tx reporter to devlink health reporters. This reporter will be
responsible for diagnosing, reporting and recovering of tx errors.
This patch declares the TX reporter operations and creates it using the
devlink health API. Currently, this reporter supports reporting and
recovering from send error CQE only. In addition, it adds diagnose
information for the open SQs.
For a local SQ recover (due to driver error report), in case of SQ recover
failure, the recover operation will be considered as a failure.
For a full tx recover, an attempt to close and open the channels will be
done. If this one passed successfully, it will be considered as a
successful recover.
The SQ recover from error CQE flow is not a new feature in the driver,
this patch re-organize the functions and adapt them for the devlink
health API. For this purpose, move code from en_main.c to a new file
named reporter_tx.c.

The hw-restart crash inject mode is a special mode, where
there is no crash generated in the firmware, but instead
the driver restarts the firmware. In order to restart WCN3990
firmware, the driver needs to send qmi_wlan_disable message
followed by the qmi_wlan_enable message to the WCN3990 firmware.
Currently the qmi_wlan_disable message is not sent to
the WCN3990 firmware when hw-restart crash is injected,
which causes the firmware to crash when the driver sends
qmi_wlan_enable message during ath10k_restart.
Send qmi_wlan_disable to the WCN3990 firmware when the

Fix unnecessary logging of message in an expected
default case where coalescing value read (via ethtool -c)
migh not be valid unless they are configured explicitly
in the hardware using ethtool -C.

Under heavy traffic load, when changing number of channels via
ethtool (ethtool -L) which will cause interface to be reloaded,
it was observed that some packets gets transmitted on old TX
channel/queue id which doesn't really exist after the channel
configuration leads to system crash.
Add a safeguard in the driver by validating queue id through
ndo_select_queue() which is called before the ndo_start_xmit().

In the case of Unified Fabric Port (UFP) mode, switch provides
the traffic class (TC) value to be used for the traffic.
Configure hardware to use this TC value for vlan priority.

When slowpath messages are sent with high rate, the resulting
events can lead to a FW assert in case they are not handled fast
enough (Event Queue Full assert). Attempt to send queued slowpath
messages only after the newly evacuated entries in the EQ ring
are indicated to FW.
