This series enhances the AMD 10GbE driver's TX queue handling during
link-down events to improve resilience, prevent resource leaks, and
enable fast failover in link aggregation configurations.

The three patches form a complete link-down handling solution:

1. Patch 1: Fast detection (know quickly when link goes down)
2. Patch 2: Quick response (stop TX immediately, skip waits)
3. Patch 3: Clean recovery (reclaim abandoned resources)

Changes since v1:
- The original patch is split into multiple patches, to better
isolate each specific improvements.

Raju Rangoju (3):
amd-xgbe: add adaptive link status polling
amd-xgbe: optimize TX shutdown on link-down
amd-xgbe: add TX descriptor cleanup for link-down
