I'm not sure it's broken.
Realtek is known to have somewhat crappy NICs that can tend to lock up
in a "middle state" if a driver probe comes too fast, and then they dont
react to any link or driver loading anymore.
One way that might help is to power off the computer, disconnect it from
power _and_ disconnect the network cables, wait a few minutes, connect
everything again and try again.
On one system I had to install Windows and disable/enable the nic and it
got back to normal :(
I also have had a system with 2 r8169 nics that when setup in
teaming/bonding, nic2 will grab the mac address from nic1, and screw up
udev nic assignments making the system boot up without lan :(
