Bug description:
[Impact]
After hot-plug the Ethernet cable, the status of Ethernet is always down.
[Fix]
Because ASPM is enabled on RTL8106E, the link change interrupt can't be fired
immediately.
Must wait a long time to get the link change interrupt.
After discuss with maintainer, he give some suggestions
1. use PHY_POLL.
2. he send a workaround(Ref. [1]) to disable ASPM on RTL8106E.
For 2, because don't know the details about operated registers in
rtl_hw_aspm_clkreq_enable, it have higher risk on power usage during
suspend.
For 1, Use PHY_POLL have a lower risk because don't change any register
operations and use polling method to query link change status.
SRU the patches for 1 first.
Currently keep discussing with Realtek but don't figure out yet.
Will re-SRU the official solution once Realtek resolve the issue.
Ref [1], https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-
next.git/commit/?id=1ee8856de82faec9bc8bd0f2308a7f27e30ba207
[Test]
Verified on machines with Realtek Ethernet device, the Ethernet works well
after hotplug 30 times.
[Regression Potential]
Medium, use polling methond may have higher cpu usage.
