When health reporter is registered to devlink, devlink will implicitly set
auto recover if and only if the reporter has a recover method. No reason
to explicitly get the auto recover flag from the driver.
Remove this flag from all drivers that called
devlink_health_reporter_create.
All existing health reporters set auto recovery to true if they have a
recover method.
Yet, administrator can unset auto recover via netlink command as prior to
this patch.

The allocated ieee_ets structure goes out of scope without being freed,
leaking memory. Appropriate result codes should be returned so that
callers do not rely on invalid data passed by reference.
Also cache the ETS config retrieved from the device so that it doesn't
need to be freed. The balance of the code was clearly written with the
intent of having the results of querying the hardware cached in the
device structure. The commensurate store was evidently missed though.

When we are in continuous NAPI polling mode, the current code in
bnxt_poll_p5() will only process the completion rings and will not
process the NQ until interrupt is re-enabled. Tis logic works and
will not cause RX or TX starvation, but async events in the NQ may
be delayed for the duration of continuous NAPI polling. These
async events may be firmware or VF events.
Continue to handle the NQ after we are done polling the completion
rings. This actually simplies the code in bnxt_poll_p5().
Acknowledge the NQ so these async events will not overflow.

Simplify the function by removing tha 'all' parameter. In the current
code, the caller has to specify whether to update/arm both completion
rings with the 'all' parameter.
Instead of this, we can just update/arm all the completion rings
that have been polled. By setting cpr->had_work_done earlier in
__bnxt_poll_work(), we know which completion ring has been polled
and can just update/arm all the completion rings with
cpr->had_work_done set.
This simplifies the function with one less parameter and works just
as well.

In bnxt_poll_p5(), the logic polls for up to 2 completion rings (RX and
TX) for work. In the current code, if we reach budget polling the
first completion ring, we will stop. If the other completion ring
has work to do, we will handle it when NAPI calls us back.
This is not optimal. We potentially leave an unproceesed entry in
the NQ. When we are finally done with NAPI polling and re-enable
interrupt, the remaining entry in the NQ will cause interrupt to
be triggered immediately for no reason.
Modify the code in bnxt_poll_p5() to keep looping until all NQ
entries are handled even if the first completion ring has reached
budget.

Replace the open-coded implementation for reading the PCIe DSN with
pci_get_dsn().
Use of put_unaligned_le64 should be correct. pci_get_dsn() will perform
two pci_read_config_dword calls. The first dword will be placed in the
first 32 bits of the u64, while the second dword will be placed in the
upper 32 bits of the u64.
On Little Endian systems, the least significant byte comes first, which
will be the least significant byte of the first dword, followed by the
least significant byte of the second dword. Since the _le32 variations
do not perform byte swapping, we will correctly copy the dwords into the
dsn[] array in the same order as before.
On Big Endian systems, the most significant byte of the second dword
will come first. put_unaligned_le64 will perform a CPU_TO_LE64, which
will swap things correctly before copying. This should also end up with
the correct bytes in the dsn[] array.
While at it, fix a small typo in the netdev_info error message when the
DSN cannot be read.

MTU changes may affect the number of IRQs so we must call
bnxt_close_nic()/bnxt_open_nic() with the irq_re_init parameter
set to true. The reason is that a larger MTU may require
aggregation rings not needed with smaller MTU. We may not be
able to allocate the required number of aggregation rings and
so we reduce the number of channels which will change the number
of IRQs. Without this patch, it may crash eventually in
pci_disable_msix() when the IRQs are not properly unwound.

The current logic that calls pci_disable_device() in __bnxt_close_nic()
during firmware reset is flawed. If firmware is still alive, we're
disabling the device too early, causing some firmware commands to
not reach the firmware.
Fix it by moving the logic to bnxt_reset_close(). If firmware is
in fatal condition, we call pci_disable_device() before we free
any of the rings to prevent DMA corruption of the freed rings. If
firmware is still alive, we call pci_disable_device() after the
last firmware message has been sent.

bnxt_ulp_start() needs to be called before SRIOV is re-enabled after
firmware reset. Re-enabling SRIOV may consume all the resources and
may cause the RDMA driver to fail to get MSIX and other resources.
Fix it by calling bnxt_ulp_start() first before calling
bnxt_reenable_sriov().
We re-arrange the logic so that we call bnxt_ulp_start() and
bnxt_reenable_sriov() in proper sequence in bnxt_fw_reset_task() and
bnxt_open(). The former is the normal coordinated firmware reset sequence
and the latter is firmware reset while the function is down. This new
logic is now more straight forward and will now fix both scenarios.
