Subject: [Intel-wired-lan] [PATCH iwl-next v6 0/6] ice: Support 5 layer Tx scheduler topology

For performance reasons there is a need to have support for selectable
Tx scheduler topology. Currently firmware supports only the default
9-layer and 5-layer topology. This patch series enables switch from
default to 5-layer topology, if user decides to opt-in.

I sent it again to iwl list, because we need to test that change,
devlink change is rather mechanical. @Tony - who should send it to
netdev list after getting Tested-by tag from our Validation?

---
v6:
- extended devlink_param *set pointer to accept one more parameter - extack
- adjusted all drivers that use *set pointer to pass one more parameter
- updated Documentation - changed "reboot" to "PCI slot powercycle", kept Kuba's ACK
- removed "Error: " prefix from NL_SET_ERR_MSG_MOD function in ice_devlink.c
- removed/adjusted messages sent to end user in ice_devlink.c

v5:
- updated Documentation commit as suggested in v4 
https://lore.kernel.org/netdev/20240228142054.474626-1-mateusz.polchlopek@intel.com/

v4:
- restored the initial way of passing firmware data to ice_cfg_tx_topo
  function in ice_init_tx_topology function in ice_main.c file. In v2
  and v3 version it was passed as const u8 parameter which caused kernel
  crash. Because of this change I decided to drop all Reviewed-by tags.

v3:
- fixed documentation warnings
https://lore.kernel.org/netdev/20231009090711.136777-1-mateusz.polchlopek@intel.com/

v2:
- updated documentation
- reorder of variables list (default-init first)
- comments changed to be more descriptive
- added elseif's instead of few if's
- returned error when ice_request_fw fails
- ice_cfg_tx_topo() changed to take const u8 as parameter (get rid of copy
  buffer)
- renamed all "balance" occurences to the new one
- prevent fail of ice_aq_read_nvm() function
- unified variables names (int err instead of int status in few
  functions)
- some smaller fixes, typo fixes
