[PATCH net-next v2 0/2] Add ICSSG firmware stats related to HSR

[MD Danish Anwar <danishanwar@ti.com>]

This series adds HSR and LRE firmware PA statistics to the TI ICSSG
ethtool stats interface, and places static_assert() guards next to the
stat descriptor arrays to catch count mismatches at build time.

Patch 1 adds static_assert() immediately after each of
icssg_all_miig_stats[] and icssg_all_pa_stats[] in icssg_stats.h,
verifying that ICSSG_NUM_MIIG_STATS and ICSSG_NUM_PA_STATS stay in
sync with the actual array sizes.

Patch 2 adds ten new firmware counters for HSR forwarding-path drops,
host-egress-path drops, and LRE duplicate-detection, updates
icssg_ndo_get_stats64() to fold the relevant counters into rx_errors
and rx_dropped, bumps ICSSG_NUM_PA_STATS to 42 (caught immediately by
the static_assert from patch 1 if the constant is ever left behind),
and documents all new entries in icssg_prueth.rst.

Changes in v2:
 - Drop the ARRAY_SIZE()-based macro approach from v1 (which caused
   binary bloat by pulling the static const arrays into every TU via
   icssg_prueth.h) as suggested by David Carlier <devnexen@gmail.com>
 - Add static_assert() next to each array in icssg_stats.h instead,
   keeping the numeric #defines and the original include graph. As
   suggested by David Carlier <devnexen@gmail.com>
