[PATCH net-next 03/10] docs: net: statistics: fix kernel-internal stats list

[Jakub Kicinski <kuba@kernel.org>]

Update the kernel-internal ethtool stats list to match current code:

- spell the entries as "struct ethtool_*_stats", not as functions
- list the full set of structures, not only pause and fec
- mention that fields are pre-initialized to ETHTOOL_STAT_NOT_SET by
  ethtool_stats_init() and drivers should leave unsupported fields at
  that value rather than zeroing them
