Marvell 88e1116 Driver Xp
Posted on -
I'll take a wild stab at this and guess from a quick google that your ethernet is not actually a Marvel 88e1116 but actually an nVidia card that uses the forcedeth driver. This was removed from el7 but ELRepo have kmod-forcedeth available. To confirm this, install Packages/pciutils-3.2.1-4.el7.x8664.rpm from the DVD though this won't help if you used the minimal CD since that doesn't have that package available.

You can always download it from a mirror, copy it to USB stick and sneakernet it across.
