Subject: [PATCH] r8169: fix data corruption issue on RTL8402
Git-commit: ef9da46ddef071e1bbb943afbbe9b38771855554
Patch-mainline: v5.9
References: bsc#1174098
[ backport note: adjusted the context slightly for 5.3.x kernel -- tiwai ]
Petr reported that after resume from suspend RTL8402 partially
truncates incoming packets, and re-initializing register RxConfig
before the actual chip re-initialization sequence is needed to avoid
the issue.
