centos7.x Physical Machine Upgrade LT kernel after Realtek, Realtek network card Realtek8169 caused by tragedy, upgrade to ML after resolution

These two days on a physical machine installed centos7.5, mainly to run Docker to do some test environment, Docker to upgrade the kernel, 3.x kernel is not enough, habitual (as in the virtual machine)

RPM--import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
RPM-UVH http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm

Yum--enablerepo=elrepo-kernel Install Kernel-lt-y

Upgrade to the LT version 4.4 kernel, re-enable the kernel boot, the results of the nightmare from now on, all kinds of configuration is no problem, but even not the internet,

Download the latest 4.4 kernel source code to compile, also tried, like, want to build their own driver module results found that Liang official links are not connected;

Finally try to kill the horse as a live horse medicine, with Yum--enablerepo=elrepo-kernel install KERNEL-ML-Y, installed ml version of the 4.1x kernel, now AH is 4.18, the results are immediately resolved,

In conclusion: It appears that the 4.4 kernel of the Realtek8169 physical network card incompatibility caused by the bug, alas, the pit father, is simply a tragedy; encounter kernel hardware adaptability, compatibility this kind of thing is really very miserable ...
