| H A D | stats.c | 449c5459 Thu Jan 19 06:26:58 CST 2023 Vladimir Oltean <vladimir.oltean@nxp.com> net: ethtool: add helpers for aggregate statistics
When a pMAC exists but the driver is unable to atomically query the
aggregate eMAC+pMAC statistics, the user should be given back at least
the sum of eMAC and pMAC counters queried separately.
This is a generic problem, so add helpers in ethtool to do this
operation, if the driver doesn't have a better way to report aggregate
stats. Do this in a way that does not require changes to these functions
when new stats are added (basically treat the structures as an array of
u64 values, except for the first element which is the stats source).
In include/linux/ethtool.h, there is already a section where helper
function prototypes should be placed. The trouble is, this section is
too early, before the definitions of struct ethtool_eth_mac_stats et.al.
Move that section at the end and append these new helpers to it.
