From d38c19b13b1087890973ac24ae2798797b8a411b Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Thu, 17 Aug 2023 16:19:08 -0700 Subject: [PATCH] bnxt_en: Increment rx_resets counter in bnxt_disable_napi() If we are doing a complete reset with irq_re_init set to true in bnxt_close_nic(), all the ring structures will be freed. New structures will be allocated in bnxt_open_nic(). The current code increments rx_resets counter in bnxt_enable_napi() if bnapi->in_reset is true. In a complete reset, bnapi->in_reset will never be true since the structure is just allocated. Increment the rx_resets counter in bnxt_disable_napi() instead. This will allow us to save all the ring error counters including the rx_resets counters in the next patch.
