Interesting. I have the same chip version (RTL8168g) and can't reproduce
the issue. Can you provide a full dmesg output and test the patch below
on top of linux-next? I'd be interested in the WARN_ON stack traces
(if any) and would like to know whether the experimental change to
__phy_modify_changed helps.

Took your patch on top of next-20190719.
See attached dmesg.
It didn't work. Same thing, lots of ping drops, no usable network.

like that:
44 packets transmitted, 2 received, 95% packet loss, time 44005ms


Maybe important:
I build a kernel with no modules.

I have to power off when I booted a kernel which doesn't work, a (soft) 
reboot into a older kernel (e.g. 4.9.y)  doesn't
fix the problem. Powering off and on does.


greetings,

       Thomas

Then, what you could do is reversing the hunks of the patch step by step.
Or make them separate patches and bisect.
Relevant are the hunks from point 1 and 2.

1. first 5 hunks (I don't think you have to reverse them individually)
   EEE-related

2. rtl8168g_disable_aldps, rtl8168g_phy_adjust_10m_aldps, rtl8168g_1_hw_phy_config
   all of these hunks are in the path for RTL8168g

3. rtl8168h_1_hw_phy_config, rtl8168h_2_hw_phy_config, rtl8168ep_1_hw_phy_config,
   rtl8168ep_2_hw_phy_config
   not in the path for RTL8168g

this is the minimal revert:

Could it be, that there is just a typo?
