Subject: [PATCH 0/2] net: mana: Refactor GF stats handling and add rx_missed_errors counter

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.
