From 90f4fd02968720bdeb38a16deeff96fa770206e4 Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Sun, 11 Apr 2021 20:18:14 -0400 Subject: bnxt_en: Refactor __bnxt_vf_reps_destroy(). Add a new helper function __bnxt_free_one_vf_rep() to free one VF rep. We also reintialize the VF rep fields to proper initial values so that the function can be used without freeing the VF rep data structure. This will be used in subsequent patches to free and recreate VF reps after error recovery.
