[Intel-wired-lan] [iwl-next v2 0/4] ice: prepare representor for SF support

[Intel-wired-lan] [iwl-next v2 0/4] ice: prepare representor for SF support

[Michal Swiatkowski]

Hi,

This is a series to prepare port representor for supporting also
subfunctions. We need correct devlink locking and the possibility to
update parent VSI after port representor is created.

Refactor how devlink lock is taken to suite the subfunction use case.

VSI configuration needs to be done after port representor is created.
Port representor needs only allocated VSI. It doesn't need to be
configured before.

VSI needs to be reconfigured when update function is called.

The code for this patchset was split from (too big) patchset [1].

v1 --> v2 [2]:
 * add returns for kdoc in ice_eswitch_cfg_vsi

[1] https://lore.kernel.org/netdev/20240213072724.77275-1-michal.swiatkowski@linux.intel.com/
[2] https://lore.kernel.org/netdev/20240419171336.11617-1-michal.swiatkowski@linux.intel.com/

  ice: move devlink locking outside the port creation
  ice: move VSI configuration outside repr setup

[Intel-wired-lan] [iwl-next v2 3/4] ice: move VSI configuration outside repr setup

[Michal Swiatkowski]

It is needed because subfunction port representor shouldn't configure
the source VSI during representor creation.

Move the code to separate function and call it only in case the VF port
representor is being created.

[Intel-wired-lan] [iwl-next v2 4/4] ice: update representor when VSI is ready

[Michal Swiatkowski]

In case of reset of VF VSI can be reallocated. To handle this case it
should be properly updated.

Reload representor as vsi->vsi_num can be different than the one stored
when representor was created.

Instead of only changing antispoof do whole VSI configuration for
eswitch.
