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.
TX timeout example:
(with auto_recover set to false, if set to true, the manual recover and
diagnose sections are irrelevant)

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 allocate 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.

A MAC address is not necessarily a unique identifier for a netdev. Drivers
such as Linux bonds, for example, can apply the same MAC address to the
upper layer device and all lower layer devices.
NFP MAC offload for tunnel decap includes port verification for reprs but
also supports the offload of non-repr MAC addresses by assigning 'global'
indexes to these. This means that the FW will not verify the incoming port
of a packet matching this destination MAC.
Modify the MAC offload logic to assign global indexes based on MAC address
instead of net device (as it currently does). Use this to allow multiple
devices to share the same MAC. In other words, if a repr shares its MAC
address with another device then give the offloaded MAC a global index
rather than associate it with an ingress port. Track this so that changes
can be reverted as MACs stop being shared.
Implement this by removing the current list based assignment of global
indexes and replacing it with an rhashtable that maps an offloaded MAC
address to the number of devices sharing it, distributing global indexes
based on this.

It is possible to receive a MAC address change notification without the
net device being down (e.g. when an OvS bridge is assigned the same MAC as
a port added to it). This means that an offloaded MAC address may not be
removed if its device gets a new address.
Maintain a record of the offloaded MAC addresses for each repr and netdev
assigned a MAC offload index. Use this to delete the (now expired) MAC if
a change of address event occurs. Only handle change address events if the
device is already up - if not then the netdev up event will handle it.

NFP repr netdevs contain private data that can store per port information.
In certain cases, the NFP driver offloads information from non-repr ports

Implement a delete message for offloaded MACs and call this on net device

events. A MAC should only be offloaded if the device is up. Note that the
netdev notifier will replay any notifications for UP devices on
registration so NFP can still offload ports that exist before the driver
is loaded. Similarly, devices need to go down before they can be
unregistered so removal of offloaded MACs is only required on down events.

QA tests report occasional timeouts on REIFY message replies. Profiling
of the two cmesg reply types under burst conditions, with a 12-core host
under heavy cpu and io load (stress --cpu 12 --io 12), show both PHY MTU
change and REIFY replies can exceed the 10ms timeout. The maximum MTU
reply wait under burst is 16ms, while the maximum REIFY wait under 40 VF
burst is 12ms. Using a 4 VF REIFY burst results in an 8ms maximum wait.
A larger VF burst does increase the delay, but not in a linear enough
way to justify a scaled REIFY delay. The worse case values between
MTU and REIFY appears close enough to justify a common timeout. Pick a
conservative 40ms to make a safer future proof common reply timeout. The
delay only effects the failure case.
Change the REIFY timeout mechanism to use wait_event_timeout() instead
of wait_event_interruptible_timeout(), to match the MTU code. In the
current implementation, theoretically, a signal could interrupt the
REIFY waiting period, with a return code of ERESTARTSYS. However, this is
caught under the general timeout error code EIO. I cannot see the benefit
of exposing the REIFY waiting period to signals with such a short delay
(40ms), while the MTU mechnism does not use the same logic. In the absence
of any reply (wakeup() call), both reply types will wake up the task after
the timeout period. The REIFY timeout applies to the entire representor
group being instantiated (e.g. VFs), while the MTU timeout apples to a
single PHY MTU change.

reduced code duplication and adds a helper function, which all the
scheduler functions call instead. Added an LED blinking handler to
ethtool. Reworked the queue management code to allow for reuse in
future XDP feature support. Updates the driver to be able to preserve
the aggregator list after reset by moving it out of port_info and into
ice_hw. Added the ability to offload SCTP checksum calculation to the
hardware. Added support for new PHY types, which support higher link
speeds.
Md Fahad makes sure that RSS lookup table and hash key get configured
during the rebuild path after a reset.
Brett updates the driver to set the physical link state according to the
netdev state (up/down). Added support for adaptive/dynamic interrupt
moderation in the ice driver, along with the ethtool operations needed.

This patch also adds the ICE_ITR_GRAN_S define that is used in the

When a netdev is set up/down we need to set the phsyical link state
accordingly. This patch adds that functionality by calling
ice_force_phys_link_state(vsi, link_up) in both the ice_stop() and
ice_open() paths.
In order to force link, ice_force_phys_link_state(vsi, link_up) will
first determine the current phy capabilities. If link has not changed
there is nothing to do. If link has changed, previous PHY capabilities
are saved and the "Enable Automatic Link Update" and "Link Establishment
State Machine (LESM)" enable bits are set. Then the new PHY config is
saved. The "Enable Automatic Link Update" will force the FW to execute
Setup link and restart auto-negotiation. This *should* then result in a
"Link Status Event (LSE)" which will cause the driver to get the current

Commit 2fd527b72b ("net: ndo_bridge_setlink: Add extack") added a new
parameter "extack" to ice_bridge_setlink but this parameter isn't used
by the function. This results in a warning: unused parameter ‘extack’
[-Wunused-parameter]. Fix that by adding an "__always_unused" qualifier.

When allocating memory pages for context memory, if the last page table
should be fully populated, the current code will set nr_pages to 0 when
calling bnxt_alloc_ctx_mem_blk(). This will cause the last page table
to be completely blank and causing some RDMA failures.
Fix it by setting the last page table's nr_pages to the remainder only
if it is non-zero.

In bnxt_hwrm_check_pf_rings(), add the proper flag to test the NQ
resources. Without the proper flag, the firmware will change
the NQ resource allocation and remap the IRQ, causing missing
IRQs. This issue shows up when adding MQPRIO TX queues, for example.
Fixes: 36d65be9a8 ("bnxt_en: Disable MSIX before re-reserving NQs/CMPL rings.")
