Hello,

I'm having network problems with the commits on r8169 since v5.2. There 
are ping packet loss, sometimes 100%, sometimes 50%. In the end network is 
unusable.

v5.2 is fine, I bisected it down to:

a2928d28643e3c064ff41397281d20c445525032 is the first bad commit
commit a2928d28643e3c064ff41397281d20c445525032

     r8169: use paged versions of phylib MDIO access functions

     Use paged versions of phylib MDIO access functions to simplify
     the code.

Reverting that commit on top of v5.2-11564-g22051d9c4a57 fixes the problem
for me (had to adjust the renaming to r8169_main.c).

I have a:
04:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd.
RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev
0c)
         Subsystem: Biostar Microtech Int'l Corp Device [1565:2400]
         Kernel driver in use: r8169

on a BIOSTAR H81MG motherboard.


greetings,

   Thomas
