Subject: [PATCH net-next v2 0/2] net: mana: Refactor GF stats handling and add rx_missed_errors counter
Date: Wed, 29 Oct 2025 03:37:50 -0700	[thread overview]
Message-ID: <1761734272-32055-1-git-send-email-ernis@linux.microsoft.com> (raw)

Restructure mana_query_gf_stats() to operate on the per-VF mana_context,
instead of per-port statistics. Introduce mana_ethtool_hc_stats to
isolate hardware counter statistics and update the
"ethtool -S <interface>" output to expose all relevant counters while
preserving backward compatibility.

Add support for the standard rx_missed_errors counter by mapping it to
the hardware's hc_rx_discards_no_wqe metric. Introduce a
dedicated workqueue that refreshes statistics every 2 seconds, ensuring
timely and consistent updates of hardware counters.

---
Changes in v2:
* Update commit message.
* Stop rescheduling workqueue only when HWC timeout is observed.
* Introduce new variable in mana_context for detecting HWC timeout.
* Warn once in mana_get_stat64 when HWC timeout is observed.
