Since commit 61e84623ace3 ("net: centralize net_device min/max MTU checking"),
mtu range is checked at dev_set_mtu().
This patch adds min_mtu for nlmon device and remove unnecessary
ndo_change_mtu() function.

Commit 3e3aaf649416 ("phy: fix mdiobus module safety") fixed the way we
dealt with MDIO bus module reference count, but sort of introduced a
regression in that, if an Ethernet driver registers its own MDIO bus
driver, as is common, we will end up with the Ethernet driver's
module->refnct set to 1, thus preventing this driver from any removal.
Fix this by comparing the network device's device driver owner against
the MDIO bus driver owner, and only if they are different, increment the
MDIO bus module refcount.

When free macvlan_port in macvlan_port_destroy, it is safe to free
directly because netdev_rx_handler_unregister could enforce one

There are two functions which would free the ipvl_port now. The first
is ipvlan_port_create. It frees the ipvl_port in the error handler,
so it could kfree it directly. The second is ipvlan_port_destroy. It
invokes netdev_rx_handler_unregister which enforces one grace period
by synchronize_net firstly, so it also could kfree the ipvl_port
directly and safely.
So it is unnecessary to use kfree_rcu to free ipvl_port.

Support for setting the RGMII_IDMODE bit was added in the commit
referenced below. However, that commit did not add the symmetrical
clearing of the bit by way of setting it in "mask". Add it here.
Note that the documentation marks clearing this bit as "reserved",
however, according to TI, support for delaying the clock does exist in
the MAC, although it is not officially supported.
We tested this on a board with an RGMII to RGMII link that will not
work unless this bit is cleared.

The CPTS drivers uses 8sec period for overflow checking with
assumption that CPTS retclk will not exceed 500MHz. But that's not
true on some TI platforms (Kesytone 2). As result, it is possible that
CPTS counter will overflow more than once between two readings.
Hence, fix it by selecting overflow check period dynamically as
max_sec_before_overflow/2, where
max_sec_before_overflow = max_counter_val / rftclk_freq.

The current implementation CPTS initialization and deinitialization
(represented by cpts_register/unregister()) does too many static
initialization from .ndo_open(), which is reasonable to do once at probe
time instead, and also require caller to allocate memory for struct cpts,
which is internal for CPTS driver in general.
This patch splits CPTS initialization and deinitialization on two parts:
- static initializtion cpts_create()/cpts_release() which expected to be
executed when parent driver is probed/removed;
- dynamic part cpts_register/unregister() which expected to be executed
when network device is opened/closed.
As result, current code of CPTS parent driver - CPSW - will be simplified
(and it also will allow simplify adding support for Keystone 2 devices in
the future), plus more initialization errors will be catched earlier. In
addition, this change allows to clean up cpts.h for the case when CPTS is
disabled.

cpts_register/unregister
There are two issues with TI CPTS code which are reproducible when TI
CPSW ethX device passes few up/down iterations:
- cpts refclk prepare counter continuously incremented after each
up/down iteration;
- devm_clk_get(dev, "cpts") is called many times.
Hence, fix these issues by using clk_disable_unprepare() in

acquired already.

TI CPTS IP is used as part of TI OMAP CPSW driver, but it's also
present as part of NETCP on TI Keystone 2 SoCs. So, It's required
to enable build of CPTS for both this drivers and this can be
achieved by allowing CPTS to be built separately.
Hence, allow cpts to be built separately and convert it to be
a module as both CPSW and NETCP drives can be built as modules.

Since the network driver and RDMA driver operate on the same PCI function,
we need to create an interface to allow the RDMA driver to share resources
with the network driver.
1. Create a new bnxt_en_dev struct which will be returned by
bnxt_ulp_probe() upon success. After that, all calls from the RDMA driver
to bnxt_en will pass a pointer to this struct.
2. This struct contains additional function pointers to register, request
msix, send fw messages, register for async events.
3. If the RDMA driver wants to enable RDMA on the function, it needs to
call the function pointer bnxt_register_device(). A ulp_ops structure
is passed for RCU protected upcalls from bnxt_en to the RDMA driver.
4. The RDMA driver can call firmware APIs using the bnxt_send_fw_msg()
function pointer.
5. 1 stats context is reserved when the RDMA driver registers. MSIX
and completion rings are reserved when the RDMA driver calls
bnxt_request_msix() function pointer.
6. When the RDMA driver calls bnxt_unregister_device(), all RDMA resources
will be cleaned up.

To better support the new RDMA driver, we need to move pci_enable_msix()

to the RDMA driver whether the network device is up or down.
Part of the existing bnxt_setup_int_mode() function is now refactored into

bnxt_init_one() to enable MSIX. The remaining logic in

In a similar fashion to how we handled exiting VLAN mode, move the logic
in i40e_vsi_add_vlan into i40e_sync_vsi_filters. Extract this logic into
its own function for ease of understanding as it will become quite
complex.
The new function, i40e_correct_mac_vlan_filters() correctly updates all
filters for when we need to enter VLAN mode, exit VLAN mode, and also
enforces the PVID when assigned.
Call i40e_correct_mac_vlan_filters from i40e_sync_vsi_filters passing it
the number of active VLAN filters, and the two temporary lists.
Remove the function for updating VLAN=0 filters from i40e_vsi_add_vlan.
The end result is that the logic for entering and exiting VLAN mode is
in one location which has the most knowledge about all filters. This
ensures that we always correctly have the non-VLAN filters assigned to
VID=0 or VID=-1 regardless of how we ended up getting to this result.
Additionally this enforces the PVID at sync time so that we know for
certain that an assigned PVID results in only filters with that PVID
will be added to the firmware.

The current flow for adding or updating the PVID for a VF uses
i40e_vsi_add_vlan and i40e_vsi_kill_vlan which each take, then release
the hash lock. In addition the two functions also must take special care
that they do not perform VLAN mode changes as this will make the code in
i40e_ndo_set_vf_port_vlan behave incorrectly.
Fix these issues by using the new helper functions i40e_add_vlan_all_mac
and i40e_rm_vlan_all_mac which expect the hash lock to already be taken.
Additionally these functions do not perform any state updates in regards
to VLAN mode, so they are safe to use in the PVID update flow.
It should be noted that we don't need the VLAN mode update code here,
because there are only a few flows here.
(a) we're adding a new PVID
In this case, if we already had VLAN filters the VSI is knocked
offline so we don't need to worry about pre-existing VLAN filters
(b) we're replacing an existing PVID
In this case, we can't have any VLAN filters except those with the old
PVID which we already take care of manually.
(c) we're removing an existing PVID
Similarly to above, we can't have any existing VLAN filters except
those with the old PVID which we already take care of correctly.
Because of this, we do not need (or even want) the special accounting
done in i40e_vsi_add_vlan, so use of the helpers is a saner alternative.
It also opens the door for a future patch which will refactor the flow
of i40e_vsi_add_vlan now that it is not needed in this function.

A future refactor of how the PF assigns a PVID to a VF will want to be
able to add and remove a block of filters by VLAN without worrying about
accidentally triggering the accounting for I40E_VLAN_ANY. Additionally
the PVID assignment would like to be able to batch several changes under
one use of the mac_filter_hash_lock.
Factor out the addition and deletion of a VLAN on all MACs into their
own function which i40e_vsi_(add|kill)_vlan can use. These new functions
expect the caller to take the hash lock, as well as perform any
necessary accounting for updating I40E_VLAN_ANY filters if we are now
operating under VLAN mode.

Fix a subtle issue with the code for converting VID=-1 filters into VID=0
filters when adding a new VLAN. Previously the code deleted the VID=-1
filter, and then added a new VID=0 filter. In the rare case that the
addition fails due to -ENOMEM, we end up completely deleting the filter
which prevents recovery if memory pressure subsides. While it is not
strictly an issue because it is likely that memory issues would result
in many other problems, we shouldn't delete the filter until after the
addition succeeds.

The current caller of i40e_update_filter_state incorrectly passes
aq_ret, an i40e_status variable, instead of the expected aq_err. This
happens to work because i40e_status is actually just a typedef integer,
and 0 is still the successful return. However i40e_update_filter_state
has special handling for ENOSPC which is currently being ignored.
Also notice that firmware does not update the per-filter response for
many types of errors, such as EINVAL. Thus, modify the filter setup so
that the firmware response memory is pre-set with I40E_AQC_MM_ERR_NO_RES.
This enables us to refactor i40e_update_filter_state, removing the need
to pass aq_err and avoiding a need for having 3 different flows for
checking the filter state.
The resulting code for i40e_update_filter_state is much simpler, only
a single loop and we always check each filter response value every time.
Since we pre-set the response value to match our expected error this
correctly works for all success and error flows.

Previous code refactors have accidentally caused issues with the
counting of active_filters. Avoid similar issues in the future by simply
re-counting the active filters every time after we handle add and delete
of all the filters. Additionally this allows us to simplify the check
for when we exit promiscuous mode since we can combine the check for
failed filters at the same time.
Additionally since we recount filters at the end we need to set
vsi->promisc_threshold as well.
The resulting code takes a bit longer since we do have to loop over
filters again. However, the result is more readable and less likely to
become incorrect due to failed accounting of filters in the future.
Finally, this ensures that it is not possible for vsi->active_filters to
ever underflow since we never decrement it.

over L4 (UDP) on the XL710 MAC. Do not advertise support for L4
timestamping.

The service task lock was being set in the scheduling function, not the
actual service task. This would potentially leave the bit set for a long
time before the task actually ran. Furthermore, if the service task
takes too long, it calls the schedule function to reschedule itself -
which would fail to take the lock and do nothing.
Instead, set and clear the lock bit in the service task itself. In the
process, get rid of the i40e_service_event_complete() function, which is
really just two lines of code that can be put right in the service task
itself.

Depending on external PHY type, register access method should be
different. Clause22 or Clause45 can be chosen for different PHYs.
Implemented functions apply correct access method for used device.

Add support for 25G devices - defines and data structures.
One tricky part here is that the firmware support for these
Devices introduces a mismatch between the PHY type enum and
the bitfields for the phy types.
This change creates a macro and uses it to increment the 25G
PHY values when creating 25G bitfields.

Replace the %d specifier used for printing vsi->active_filters and
vsi->promisc_threshold with an unsigned %u format specifier. While it is
unlikely in practice that these values will ever reach such a large
number they are unsigned values and thus should not be interpreted as
negative numbers.

Before this patch "ethtool -p" was not blinking the LEDs on boards
with 1G BaseT PHYs.
This commit identifies 1G BaseT boards as having the LEDs connected
to the MAC. Also, renamed the flag to be more descriptive of usage.
The flag is now I40E_FLAG_PHY_CONTROLS_LEDS.

The netdev->dev_addr MAC filter already exists in the
MAC/VLAN hash table, as it is added when we configure
the netdev in i40e_configure_netdev. Because we already
know that this address will be updated in the
hash_for_each loops, we do not need to handle it
specially. This removes duplicate code and simplifies
the i40e_vsi_add_vlan and i40e_vsi_kill_vlan functions.
Because we know these filters must be part of the
MAC/VLAN hash table, this should not have any functional
impact on what filters are included and is merely a code
simplification.

Currently the function i40e_napi-poll() returns 0 when it clean completely
the Rx rings, but this foul budget accounting in core code.
Fix this by returning the actual work done, capped to budget - 1, since
the core doesn't allow to return the full budget when the driver modifies
the NAPI status
This is based on a similar change that was made for the ixgbe driver by
Paolo Abeni.

A previous commit 53cb6e9e8949 ("i40e: Removal of workaround for simple
MAC address filter deletion") removed a workaround for some
firmware versions which was reported to not be necessary in production
NICs. Unfortunately this workaround is necessary in some configurations,
specifically the Ethernet Controller XL710 for 40GbE QSFP+ (8086:1583).
Without this patch, the mentioned NICs with current firmware exhibit
issues when adding VLANs, as outlined by the following reproduction:
$modprobe i40e
$ip link set <device> up
$ip link add link <device> vlan100 type vlan id 100
$dmesg | tail
<snip>
kernel: i40e 0000:82:00.0: Error I40E_AQ_RC_EINVAL adding RX
filters on PF, promiscuous mode forced on
This results in filters being marked as FAILED and setting the device in
promiscuous mode.
The root cause of receiving the -EINVAL error response appears to be due
to a conflict with the default MAC filter which still exists on the
default firmware for this device. Attempting to add a new VLAN filter on
the default MAC address conflicts with the IGNORE_VLAN setting on the
default rule.

The i40e_txd_use_count function was fast but confusing. In the comments,
it even admits that it's ugly. So replace it with a new function that is
(very) slightly faster and has extensive commenting to help the thicker
among us (including the author, who will forget in a week) understand
how it works.

This patch makes the driver log link speed change. Before applying the
patch link messages were printed only on state change. Now message is
printed when link is brought up or down and when speed changes.
