Hi Ping-Ke,
After applied your patches on 5.17-rc7, tested on pci device:
04:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. Device [10ec:8852]
I found the performance is a bit poor on TX especially.
Tested on Intel AX210, it's result is TX 461Mb/s and RX 547Mb/s at the same position.

Also I found some errors when stress test, not sure how to reproduce yet, copy log here:
