Subject: [PATCH net-next 03/12] bnxt_en: Increment rx_resets counter in bnxt_disable_napi()
Date: Mon, 14 Aug 2023 21:56:49 -0700	[thread overview]
Message-ID: <20230815045658.80494-4-michael.chan@broadcom.com> (raw)
In-Reply-To: <20230815045658.80494-1-michael.chan@broadcom.com>

[-- Attachment #1: Type: text/plain, Size: 1707 bytes --]

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.
