The NVM contents are read via firmware by using the ice_aq_read_nvm
function. This function has a couple of limits:
1) The AdminQ commands can only take buffers sized up to 4Kb. Thus, any
larger read must be split into multiple reads.
2) when reading from the Shadow RAM, reads must not cross sector
boundaries. The sectors are also 4Kb in size.
Implement the ice_read_flat_nvm function to read portions of the NVM by
flat offset. That is, to read using offsets from the start of the NVM
rather than from a specific module.
This function will be able to read both from the NVM and from the Shadow
RAM. For simplicity NVM reads will always be broken up to not cross 4Kb
page boundaries, even though this is not required unless reading from
the Shadow RAM.
Use this new function as the implementation of ice_read_sr_word_aq.
The ice_read_sr_buf_aq function is not modified here. This is because
a following change will remove the only caller of that function in favor
of directly using ice_read_flat_nvm. Thus, there is little benefit to
changing it now only to remove it momentarily. At the same time, the
ice_read_sr_aq function will also be removed.

The ice_read_sr_aq function returns words in the Little Endian format.
Remove the need for __force and typecasting by using a local variable in
the ice_read_sr_word_aq function.
Additionally clarify explicitly that the ice_read_sr_aq function takes
storage for __le16 values instead of using u16.
Being explicit about the endianness of this data helps when using tools
like sparse to catch endian-related issues.

Driver reclaims descriptors in much smaller batches, even if hardware
indicates more to reclaim, during backpressure. So, fix the check to
restart the Txq during backpressure, by looking at how many
descriptors hardware had indicated to reclaim, and not on how many
descriptors that driver had actually reclaimed. Once the Txq is
restarted, driver will reclaim even more descriptors when Tx path
is entered again.

commit 7c3bebc3d868 ("cxgb4: request the TX CIDX updates to status page")
reverted back to getting Tx CIDX updates via DMA, instead of interrupts,
introduced by commit d429005fdf2c ("cxgb4/cxgb4vf: Add support for SGE
doorbell queue timer")
However, it missed reverting back several code changes where Tx CIDX
updates are not explicitly requested during backpressure when using
interrupt mode. These missed changes cause slow recovery during
backpressure because the corresponding interrupt no longer comes and
hence results in Tx throughput drop.
So, revert back these missed code changes, as well, which will allow
explicitly requesting Tx CIDX updates when backpressure happens.
This enables the corresponding interrupt with Tx CIDX update message
to get generated and hence speed up recovery and restore back
throughput.

During initialization the driver issues a software reset command and
then waits for the system status to change back to "ready" state.
However, before issuing the reset command the driver does not check that
the system is actually in "ready" state. On Spectrum-{1,2} systems this
was always the case as the hardware initialization time is very short.
On Spectrum-3 systems this is no longer the case. This results in the
software reset command timing-out and the driver failing to load:
[ 6.347591] mlxsw_spectrum3 0000:06:00.0: Cmd exec timed-out (opcode=40(ACCESS_REG),opcode_mod=0,in_mod=0)
[ 6.358382] mlxsw_spectrum3 0000:06:00.0: Reg cmd access failed (reg_id=9023(mrsr),type=write)

[ 6.375274] mlxsw_spectrum3: probe of 0000:06:00.0 failed with error -110
Fix this by waiting for the system to become ready both before issuing
the reset command and afterwards. In case of failure, print the last
system status to aid in debugging.

Chelsio NICs have 3 filter regions, in following order of priority:
1. High Priority (HPFILTER) region (Highest Priority).
2. HASH region.
3. Normal FILTER region (Lowest Priority).
Currently, there's a 1-to-1 mapping between the prio value passed
by TC and the filter region index. However, it's possible to have
multiple TC rules with the same prio value. In this case, if a region
is exhausted, no attempt is made to try inserting the rule in the
next available region.
So, rework and remove the 1-to-1 mapping. Instead, dynamically select
the region to insert the filter rule, as long as the new rule's prio
value doesn't conflict with existing rules across all the 3 regions.

last_keep_alive_jiffies is updated in probe and when a keep-alive
event is received. In case the driver times-out on a keep-alive event,
it has high chances of continuously timing-out on keep-alive events.
This is because when the driver recovers from the keep-alive-timeout reset
the value of last_keep_alive_jiffies is very old, and if a keep-alive
event is not received before the next timer expires, the value of
last_keep_alive_jiffies will cause another keep-alive-timeout reset
and so forth in a loop.
Solution:
Update last_keep_alive_jiffies whenever the device is restored after
reset.

Bug:
In short the main issue is caused by the fact that the number of queues
is changed using ethtool after ena_probe() has been called and before
ena_up() was executed. Here is the full scenario in detail:
* ena_probe() is called when the driver is loaded, the driver is not up
yet at the end of ena_probe().
* The number of queues is changed -> io_queue_count is changed as well -
ena_up() is not called since the "dev_was_up" boolean in
ena_update_queue_count() is false.
* ena_up() is called by the kernel (it's called asynchronously some
time after ena_probe()). ena_setup_io_intr() is called by ena_up() and
it uses io_queue_count to get the suitable irq lines for each msix
vector. The function ena_request_io_irq() is called right after that
and it uses msix_vecs - This value only changes during ena_probe() and
ena_restore() - to request the irq vectors. This results in "Failed to
request I/O IRQ" error for i > io_queue_count.
Numeric example:
* After ena_probe() io_queue_count = 8, msix_vecs = 9.
* The number of queues changes to 4 -> io_queue_count = 4, msix_vecs = 9.
* ena_up() is executed for the first time:
** ena_setup_io_intr() inits the vectors only up to io_queue_count.
** ena_request_io_irq() calls request_irq() and fails for i = 5.
How to reproduce:
simply run the following commands:
sudo rmmod ena && sudo insmod ena.ko;
sudo ethtool -L eth1 combined 3;
Fix:
Use ENA_MAX_MSIX_VEC(adapter->num_io_queues + adapter->xdp_num_queues)
instead of adapter->msix_vecs. We need to take XDP queues into
consideration as they need to have msix vectors assigned to them as well.
Note that the XDP cannot be attached before the driver is up and running
but in XDP mode the issue might occur when the number of queues changes
right after a reset trigger.
The ENA_MAX_MSIX_VEC simply adds one to the argument since the first msix
vector is reserved for management queue.

Overview:
We don't frequently change the msix vectors throughout the life cycle of
the driver. We do so in two functions: ena_probe() and ena_restore().
ena_probe() is only called when the driver is loaded. ena_restore() on the
other hand is called during device reset / resume operations.
We use num_io_queues for calculating and allocating the number of msix
vectors. At ena_probe() this value is equal to max_num_io_queues and thus
this is not an issue, however ena_restore() might be called after the
number of io queues has changed.
A possible bug scenario is as follows:
* Change number of queues from 8 to 4.
(num_io_queues = 4, max_num_io_queues = 8, msix_vecs = 9,)
* Trigger reset occurs -> ena_restore is called.
(num_io_queues = 4, max_num_io_queues =8 , msix_vecs = 5)
* Change number of queues from 4 to 6.
(num_io_queues = 6, max_num_io_queues = 8, msix_vecs = 5)
* The driver will reset due to failure of check_for_rx_interrupt_queue()
Fix:
This can be easily fixed by always using max_num_io_queues to init the
msix_vecs, since this number won't change as opposed to num_io_queues.

As noted in commit 28c2d1a7a0bf ("net: bcmgenet: enable loopback
during UniMAC sw_reset") the UniMAC must be clocked at least 5
cycles while the sw_reset is asserted to ensure a clean reset.
That commit enabled local loopback to provide an Rx clock from the
GENET sourced Tx clk. However, when connected in MII mode the Tx
clk is sourced by the PHY so if an EPHY is not supplying clocks
(e.g. when the link is down) the UniMAC does not receive the
necessary clocks.
This commit extends the sw_reset window until the PHY reports that
the link is up thereby ensuring that the clocks are being provided
to the MAC to produce a clean reset.
One consequence is that if the system attempts to enter a Wake on
LAN suspend state when the PHY link has not been active the MAC
may not have had a chance to initialize cleanly. In this case, we
remove the sw_reset and enable the WoL reception path as normal
with the hope that the PHY will provide the necessary clocks to
drive the WoL blocks if the link becomes active after the system
has entered suspend.

If udevd is configured to rename interfaces according to persistent
naming rules and if a network interface has phys_port_name in sysfs,
its contents will be appended to the interface name.
However, register_netdev creates device in sysfs and if
devlink_port_register is called after that, there is a timeframe in
which udevd may read an empty phys_port_name value. The consequence is
that the interface will lose this suffix and its name will not be
really persistent.
The solution is to register the port before registering a netdev.

The original condition rejected all egress rules that
are not on tunnel device.
Also, the whole point of this egress reject was to disallow bad
rules because of egdev which doesn't exists today, so remove
this check entirely.
