Subject: [PATCH net-next v4 0/4] net: wangxun: complete ethtool coalesce options

Support to use adaptive RX coalescing. Change the default RX coalesce
usecs and limit the range of parameters for various types of devices,
according to their hardware design.

---
v4:
- split into 4 patches
- add performance test result for NGBE changes
- use U16_MAX instead of self-defined macro
- add adaptive-tx coalesce for DIM tx work
- avoid setting itr in DIM work when adaptive coalesce is off

v3: https://lore.kernel.org/all/20250724080548.23912-1-jiawenwu@trustnetic.com/
- detail the commits messages
- support DIM algorithm

v2: https://lore.kernel.org/all/20250721080103.30964-1-jiawenwu@trustnetic.com/
- split into 3 patches
- add missing functions
- adjust the weird codes and comments
