For checking if cable is plugged:
% cat /sys/class/net/ep0/carrier
1
For checking, if it's RJ45 -- ioctl() that ethtool uses to check used
port (you can also use ioctl() to check if link is detected).
For checking if cable is plugged and there is valid network
configuration -- ask NetworkManager, I think.
