[ Upstream commit 70f92ab97042f243e1c8da1c457ff56b9b3e49f1 ]
After resume from S4 (hibernate), RTL8168H/RTL8111H truncates incoming packets. Packet captures show messages like "IP truncated-ip - 146 bytes missing!".
The issue is caused by RxConfig not being properly re-initialized after resume. Re-initializing the RxConfig register before the chip re-initialization sequence avoids the truncation and restores correct packet reception.
This follows the same pattern as commit ef9da46ddef0 ("r8169: fix data corruption issue on RTL8402").
