[PATCH net-next v2 0/2] net: stmmac: Add support for coarse timestamping

From: Maxime Chevallier

Hello everyone,

This is V2 for coarse timetamping support in stmmac. This version uses a
dedicated devlink param "ts_coarse" to control this mode.

This doesn't conflict with Russell's cleanup of hwif.

Changes in V2:
- Use devlink intead of tsconfig
- Rebase on top of Russell's rework of has_xxx flags
