[PATCH iwl-next v2 0/7] i40e: cleanups & refactors

[Ivan Vecera]

This series do following:
Patch 1 - Removes write-only flags field from i40e_veb structure and
          from i40e_veb_setup() parameters
Patch 2 - Refactors parameter of i40e_notify_client_of_l2_param_changes()
          and i40e_notify_client_of_netdev_close()
Patch 3 - Refactors parameter of i40e_detect_recover_hung()
Patch 4 - Adds helper i40e_pf_get_main_vsi() to get main VSI and uses it
          in existing code
Patch 5 - Consolidates checks whether given VSI is the main one
Patch 6 - Adds helper i40e_pf_get_main_veb() to get main VEB and uses it
          in existing code
Patch 7 - Adds helper i40e_vsi_reconfig_tc() to reconfigure TC for
          particular and uses it to replace existing open-coded pieces

Changes since v1:
- adjusted titles for patches 2 & 3

[PATCH iwl-next v2 2/7] i40e: Refactor argument of several client notification functions

[Ivan Vecera]

Commit 0ef2d5afb12d ("i40e: KISS the client interface") simplified
the client interface so in practice it supports only one client
per i40e netdev. But we have still 2 notification functions that
uses as parameter a pointer to VSI of netdevice associated with
the client. After the mentioned commit only possible and used
VSI is the main (LAN) VSI.
So refactor these functions so they are called with PF pointer argument
and the associated VSI (LAN) is taken inside them.

[Intel-wired-lan] [PATCH iwl-next v2 2/7] i40e: Refactor argument of several client notification functions

[Ivan Vecera]

Commit 0ef2d5afb12d ("i40e: KISS the client interface") simplified
the client interface so in practice it supports only one client
per i40e netdev. But we have still 2 notification functions that
uses as parameter a pointer to VSI of netdevice associated with
the client. After the mentioned commit only possible and used
VSI is the main (LAN) VSI.
So refactor these functions so they are called with PF pointer argument
and the associated VSI (LAN) is taken inside them.

Commit 07d44190a389 ("i40e/i40evf: Detect and recover hung queue
scenario") changes i40e_detect_recover_hung() argument type from
i40e_pf* to i40e_vsi* to be shareable by both i40e and i40evf.
Because the i40evf does not exist anymore and the function is
exclusively used by i40e we can revert this change.

[Intel-wired-lan] [PATCH iwl-next v2 4/7] i40e: Add helper to access main VSI

[Ivan Vecera]

Add simple helper i40e_pf_get_main_vsi(pf) to access main VSI
that replaces pattern 'pf->vsi[pf->lan_vsi]'

[PATCH iwl-next v2 5/7] i40e: Consolidate checks whether given VSI is main

[Ivan Vecera]

In the driver code there are 3 types of checks whether given
VSI is main or not:
1. vsi->type ==/!= I40E_VSI_MAIN
2. vsi ==/!= pf->vsi[pf->lan_vsi]
3. vsi->seid ==/!= pf->vsi[pf->lan_vsi]->seid

All of them are equivalent and can be consolidated. Convert cases
2 and 3 to case 1.
