====================
dp83tg720: Reduce link recovery
This patch series improves the link recovery behavior of the TI
DP83TG720 PHY driver.
Previously, we introduced randomized reset delay logic to avoid reset
collisions in multi-PHY setups. While this approach was functional, it
had notable drawbacks: unpredictable behavior, longer and more variable
link recovery times, and overall higher complexity in link handling.
With this new approach, we replace the randomized delay with
deterministic, role-specific delays in the PHY reset logic. This enables
us to:
- Remove the redundant empirical 600 ms delay in read_status()
- Drop the random polling interval logic
- Introduce a clean, adaptive polling strategy with consistent
behavior and improved responsiveness
As a result, the PHY is now able to recover link reliably in under
1000_ms
