[PATCH net-next v4 0/3] Add standard stats for HSR/PRP

[MD Danish Anwar]

Add standard stats for HSR / PRP. This series was initially adding HSR/PRP
related stats for ICSSG driver. Based on maintainers' comments on v2 I am
now adding support to dump standard stats for HSR/PRP.

The drivers which support offload can populate these standard stats.

This series only implements offloaded stats. For software-only interfaces
Felix Maurer had said he will do it later [1]

v3 - v4:
*) Address AI review comments on Patch 1/3 and Patch 3/3. AI review comments
on patch 2/3 were not relevant to this series.

v3 https://lore.kernel.org/all/20260608100930.210149-1-danishanwar@ti.com/
v2 https://lore.kernel.org/all/20260514075605.850674-1-danishanwar@ti.com/
