Add callbacks
=============
.selftest_check: returns true for flash selftest.
.selftest_run: runs a flash selftest.
Also, refactor NVM APIs so that they can be
used with devlink and ethtool both.

Instead of always returning -ENOPKG, decode the firmware error
code further when the HWRM_NVM_INSTALL_UPDATE firmware call fails.
Return a more suitable error code to userspace and log an error
in dmesg.
This is version 2 of the earlier patch that was reverted:
02acd399533e ("bnxt_en: parse result field when NVRAM package install fails")
In this new version, if the call is made through devlink instead of
ethtool, we'll also set the error message in extack.

On older firmware that doesn't support the HWRM_NVM_GET_DEV_INFO
command that returns detailed stored firmware versions, fallback
to use the same firmware package version that is reported to ethtool.
Refactor bnxt_get_pkgver() in bnxt_ethtool.c so that devlink can call
and get the package version.

Similar to reload driver_reinit, the RTNL lock is held across reload
down and up to prevent interleaving state changes. But we need to
subsequently release the RTNL lock while waiting for firmware reset
to complete.
Also keep a statistic on fw_activate resets initiated remotely from
other functions.

All drivers which implement the devlink flash update support, with the
exception of netdevsim, use either request_firmware or
request_firmware_direct to locate the firmware file. Rather than having
each driver do this separately as part of its .flash_update
implementation, perform the request_firmware within net/core/devlink.c
Replace the file_name parameter in the struct devlink_flash_update_params
with a pointer to the fw object.
Use request_firmware rather than request_firmware_direct. Although most
Linux distributions today do not have the fallback mechanism
implemented, only about half the drivers used the _direct request, as
compared to the generic request_firmware. In the event that
a distribution does support the fallback mechanism, the devlink flash
update ought to be able to use it to provide the firmware contents. For
distributions which do not support the fallback userspace mechanism,
there should be essentially no difference between request_firmware and
request_firmware_direct.

Add a new bnxt_hwrm_nvm_get_dev_info() to query firmware version
information via NVM_GET_DEV_INFO firmware command. Use it to
get the running version of the NVM configuration information.
This new function will also be used in subsequent patches to get the
stored firmware versions.

The ethtool ABI specifies that the reset operation should only clear
the flags that were actually reset. Setting the flags to zero after
a chip reset violates this because it does not include resetting the
application processor complex. Similarly, components that are not yet
defined are also not necessarily being reset.
The fact that chip reset does not cover the AP also means that it is
inappropriate to treat these two components exclusively of one another.
The ABI provides a mechanism to report a failure to reset independent
components via the returned bitmask, so it is also wrong to fail hard
if one of a set of independent resets is not possible.
It is incorrect to rely on the passed by reference flags in bnxt_reset(),
which are being updated as components are reset. The initially requested
value should be used instead so that hard errors do not propagate if any
earlier components could have been reset successfully.
Note, AP and chip resets are global in nature. Dedicated resets are
thus not currently supported.

If any change happened in the configuration of VF in VM while
collecting live dump, there could be a race and firmware can return
more data than allocated dump length. Fix it by keeping track of
the accumulated core dump length copied so far and abort the copy
with error code if the next chunk of core dump will exceed the
original dump length.

Driver supports 2 types of core dumps.
1. Live dump - Firmware dump when system is up and running.
2. Crash dump - Dump which is collected during firmware crash
that can be retrieved after recovery.
Crash dump is currently supported only on specific 58800 chips
which can be retrieved using OP-TEE API only, as firmware cannot
access this region directly.
User needs to set the dump flag using following command before
initiating the dump collection:
$ ethtool -W|--set-dump eth0 N
Where N is "0" for live dump and "1" for crash dump
Command to collect the dump after setting the flag:
$ ethtool -w eth0 data Filename
v3: Modify set_dump to support even when CONFIG_TEE_BNXT_FW=n.
Also change log message to netdev_info().

1. Add bnxt_hwrm_set_eee() function to setup EEE firmware parameters based
on the bp->eee settings.
2. The new function bnxt_eee_config_ok() will check if EEE parameters need

3. bnxt_hwrm_set_link() has added a new parameter to update EEE. If the
parameter is set, it will call bnxt_hwrm_set_eee().

Broadcom ethernet driver for the new family of NetXtreme-C/E
ethernet devices.
v5:
- Removed empty blank lines at end of files (noted by David Miller).
- Moved busy poll helper functions to bnxt.h to at least make the
.c file look less cluttered with #ifdef (noted by Stephen Hemminger).
v4:
- Broke up 2 long message strings with "\n" (suggested by John Linville)
- Constify an array of strings (suggested by Stephen Hemminger)
- Improve bnxt_vf_pciid() (suggested by Stephen Hemminger)
- Use PCI_VDEVICE() to populate pci_device_id table for more compact
source.
v3:
- Fixed 2 more sparse warnings.
- Removed some unused structures in .h files.
v2:
- Fixed all kbuild test robot reported warnings.
- Fixed many of the checkpatch.pl errors and warnings.
- Fixed the Kconfig description (noted by Dmitry Kravkov).
