[PATCH 6.6 080/102] ice: remove unnecessary duplicate checks for VF VSI ID

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jacob Keller <jacob.e.keller@xxxxxxxxx>

commit 363f689600dd010703ce6391bcfc729a97d21840 upstream.

The ice_vc_fdir_param_check() function validates that the VSI ID of the
virtchnl flow director command matches the VSI number of the VF. This is
already checked by the call to ice_vc_isvalid_vsi_id() immediately
following this.

This check is unnecessary since ice_vc_isvalid_vsi_id() already confirms
this by checking that the VSI ID can locate the VSI associated with the VF
structure.

Furthermore, a following change is going to refactor the ice driver to
report VSI IDs using a relative index for each VF instead of reporting the
PF VSI number. This additional check would break that logic since it
enforces that the VSI ID matches the VSI number.

Since this check duplicates  the logic in ice_vc_isvalid_vsi_id() and gets
in the way of refactoring that logic, remove it.
