Since 4.30 firmware exposes internal thermal sensor reading via admin
queue commands. Expose those readouts via hwmon API when supported.
Driver provides current reading from HW as well as device specific
thresholds for thermal alarm (Warning, Critical, Fatal) events.

Yes, for alignment ("RXH_SYMMETRIC_XOR" is too long
Patch 1 adds the support at the Kernel level, allowing the user to set a
symmetric RSS hash for any flow type via:
# ethtool -N|-U eth0 rx-flow-hash s|d|f|n symmetric-xor
Support for the new "symmetric-xor" flag will be later sent to the
"ethtool" user-space tool.
Patch 2 fixes a long stand
Symmetric RSS hash functions are beneficial in applications that monitor
both Tx and Rx packets of the same flow (IDS, software firewalls, ..etc).
Getting all traffic of the same flow on the same RX queue results in
higher CPU cache efficiency.
A NIC that supports "symmetric-xor" can achieve this
Fix the values of the ICE_AQ_VSI_Q_OPT_RSS_* registers. Shifting is
already done when the values are used, no need to double shift. Bug was
not discovered earlier since only ICE_AQ_VSI_Q_OPT_RSS_TPLZ (Zero) is
currently used.
Also, rename ICE_AQ_VSI_Q_OPT_RSS_XXX to ICE_AQ_VSI_Q_OPT_RSS_HASH_XXX

Refactor the driver to use a communication data structure for RSS
config. To do so we introduce the new ice_rss_hash_cfg struct, and then
pass it as an argument to several functions.
Also introduce enum ice_rss_cfg_hdr_type to specify a more granular and
flexible RSS configuration
The flow director and RSS blocks use separate methods to generate a
unique 64 bit ID for the flow. This is not extendable, especially for
the RSS that already uses all 64 bit space.
Refactor the flow generation API so that the ID is generated within
ice_flow_add_prof(). The FD and RSS blocks cache

The hash function in the E800 NICs is set per-VSI and a specific AQ
command is needed to modify the hash function. Use the AQ command to
enable setting the symmetric Toeplitz RSS hash function for any VSI.
When the Symmetric Toeplitz hash function is used, the hardware sets the

Allow the VFs to support symmetric RSS for any flow type. The symmetric
RSS will not be supported on PFs not advertising the ADV RSS Offload
flag (ADV_RSS_SUPPORT()), for example the E700 series (i40e).

The first 3 patches are quite simple cleanups.
Patch 4 removes the whole unused iavf client interface and the
supporting code.
Michal Schmidt (4):
iavf: rely on netdev's own registered state
iavf: use unregister_netdev
iavf: add a common function for undoing the interrupt scheme
iavf: dele
The iavf client interface was added in 2017 by commit ed0e894de7c1
("i40evf: add client interface"), but there have never been any in-tree
callers.
It's not useful for future development either. The Intel out-of-tree
iavf and irdma drivers instead use an auxiliary bus, which is a better
solution.
The information whether a netdev has been registered is already present
in the netdev itself. There's no need for a driver flag with the same
meaning.

Add a new function iavf_free_interrupt_scheme that does the inverse of
iavf_init_interrupt_scheme. Symmetry is nice. And there will be three
callers already.

Use unregister_netdev, which takes rtnl_lock for us. We don't have to
check the reg_state under rtnl_lock. There's nothing to race with. We
have just cancelled the finish_config work.
