[elrepo] How to add r8168 kmod to kernel src tree

[Scott Johnson]

Currently, my server uses the r8169 nic driver, but it fails to come
up about half the time during pxeboot:

r8169: eth0: link down
ADDRCONF(NETDEV_UP): eth0: link is not ready

>From my internet search and forum browsing, looks like one solution
might be to use the r8168 driver instead.  My lspci output seems to
support what others have done as well.  However, I don't see the r8168
kmod available in the kernel menuconfig.  I need to build my nic
driver into a bzImage for pxeboot.

I can get the r8168 src from the Realtek website and there is a kmod
package here on elrepo.org, however what I need is to build the r8168
driver into a kernel bzImage, instead of just built as a module.

Anyone know how I can patch the kernel tree to include the r8168
driver?  Maybe there is some good help somewhere on how to do this?
