net: mana: Add standard counter rx_missed_errors

Browse source

Report standard counter stats->rx_missed_errors
using hc_rx_discards_no_wqe from the hardware.

Add a global workqueue to periodically run
mana_query_gf_stats every 2 seconds to get the latest
info in eth_stats and define a driver capability flag
to notify hardware of the periodic queries.

To avoid repeated failures and log flooding, the workqueue
is not rescheduled if mana_query_gf_stats fails on HWC timeout
error and the stats are reset to 0. Other errors are transient
which will not need a VF reset for recovery.
